Docket Nos. STN 50-528/529/530 Final Environmental Statement Related to Construction of Palo Verde Nuclear Generating Station File: 79-054-026

Dear Dr. Gilbert:

Construction of the wastewater conveyance pipeline has been completed in several portions of the overall right-of-way. Our Land department has received a letter (Enclosure

1) from the Buckeye Town;Manager requesting that we initiate some type of weed control on the ANPP right-of-way through the town.

We have also had similar requests from farmers located adjacent to our ROW up to 8 miles west of Buckeye. The total acreage affected is approximately 30 acres. The preferred and most cost-effective method of weed control is the application of a weed killer chemical followed by discing as needed. Paragraph 4.5.1, Item 21 of the Final Environmental Statement related to construction of Palo Verde Nuclear Generating Station Units 1,283 appears to prohibit the use of weed killer chemicals along the pipeline ROW. Considering the weed problem now in evidence, we are requesting an exemption from this requirement for the specified portions of the ROW. Details of the areas to be sprayed are discussed in a memo from the APS Land department to E. E. Van Brunt, Jr. (Enclosure 2). Application would be at a rate of 5 pounds per acre, once per year.

Dr. Robert A. Gilbert October 2, 1979 ANPP-13943 - JMA/JRM Page 2 Enclosure 3 is a request from the APS Land department to Desert Weed Control for information on weed.control 'products. Enclosure 4 is a letter from E. I. DuPont De Nemours 8 Co. to Desert Weed Control describing KARMEX Weed Killer, which is the preferred agent for this application. Please evaluate the environmental impact of this application and advise us if we may proceed. Very truly yours, CLI~Qn L4.l E. E.

Dear Mr. Buck:

Please let this service as an official request from the Town of Buckeye to initiate some type of weed control measures along the ANPP water conveyance pipeline through the Town. The present abundance of weeds not only creates an eye-sore but could become a potential fire hazard. Your earliest consideration of this request would be greatly appreciated. Sincerely, Steven L.

Buck, Right of May Project Leader, Land Department sUQJEcT: PVNGS Mater Pipeline Meed Control I Enclosed are the right of way maps with the potential weed hazard areas indicated in red. This area consists of approximately 30,acres and is located within the Town limits of Buckeye and extends 8 miles West to the Hassayampa River. If these areas remain uncontrolled, they present a two-fold problem to the local residents: 1. Weeds located adjacent to farmland will result in a reduced crop yield, and increased cost to the farmers for weed eradication within their farmland. I 2. The weeds, upon reaching maturity, are in excess of 3 feet in " height and present a potential fire hazard to the farmlands and buildings and residences located within the town limits. The Town Manager of Buckeye has made a verbal request that we perform some type of weed control to eliminate this potential hazard. I have not as yet received from the applicator, the type of chemicals to be used or the frequency of application. I have also requested information concerning the cost of discing in the event that chemical sprays are not allowed. I will provide this information upon receiving it from the applicator. PHB:nr Enc.

Dear Mr. Gable:

Pursuant to our meeting of July 9th, I am enclosing maps indicating the PVNGS Pipeline Right of Way. The areas indicated in red consisting of approximately 30 acres, present a potential weed hazard area.

However, before allowing any work to be performed on these areas, we are required to provide the Nuclear Regulatory Commission with the following informa-tion:

The type of chemical to be used for the weed eradication and its potential toxic affect on humans or farm vegetation, if any. Also, the frequency of application that will be required to provide reasonable control. \\ I need these two items plus you are to provide me with the cost for discing the weeds on approximately 5 acres between 4th Street and Miller Road. Please write your reply on t'e back of this letter and return to me in the enclosed envelope. Sincerely, Senior Right of Way Agent Land Department PMB:nr Enc.

Dear Mr. Gable:

With reference to your letter of July 30, KARMEX Weed Killer is registered with the U. S. Environmental Protection Agency for non-crop weed control and for selective use in crops, as detailed in the enclosed product labeling. Technical information on the active ingredient, diuron, is furnished in the enclosed Technical Data Sheet. You will note that diuron has a low order of toxicity and presents little hazard to humans. It also has low acute oral toxicity to farm animals (cattle, sheep) as shown by the enclosed excerpt from "The Toxicity of Some Organic Herbicides to Cattle, Sheep and Chickens", J. S. Palmer and R. D. Radeleff, U.ST 0.A. Production Research Report No. 106, May 1969. From their studies with diuron, the U.S.D.A. investigators concluded that "the 9.6 pound rate would not be 'hazardous for cattle and sheep"; this is twice the use rate indicated in your letter. Thanks for contacting us, Mr. Gable, and we trust this information will be helpful to you. Yours very truly, DER/pah Enc. D. E.

{table 12). One yearling. dosed at, 100 mg./kg. by drench was poisoned; another dosed bp capsule had no ill effects. One sheep dosed at 100 mg./kg. by drench was poisoned after 2 doses and had a significant weight loss during the next 8 days. Chickens dosed at 10 mg./kg. showed a significant decrease in wei ht oain. One chicken died at 100 mg./kg. after 10; tIie 4 surviving chickens showed iieiglit loss. Signs of poisoning in the yearling and the sheep were anorexiadepression,

dyspnea, and prostration. In the 2 poisoned

sheep, an un-

'oordinated gait was observed. Both sheep re-covered after treatment was discontinued. At necropsr on chickens, there was congestion of the intestinal mucosa and an enlarged, congested liver. Application rates for diuron most commonly range from,0.2 to 9.6 pounds actual per acre. Rates in excess of 1 pound per acre would be hazardous for chickens. The 9.6-pound rate would not be hazardous for cattle and sheep. A rate of 80 iiounds actual per acre is used in irrigation ditches and would be highly hazardous for all three test species.

GENERAL INFORMATION Du Pont"Karmex" Weed Killeris a wettable powder to be mixed in water and applied as a spray for selective control of weeds in certain crops and for nonselective weed control on non cropland areas. It is non. corrosive to equipment, nonflammable and nonvolatile. "Karmex" may be applied to soil prior to emergence ofw~ to control susceptible weed seedlings lor an extended period of time: the degree of control and duration of effect willvary with the amount of chemical applied, soil texture, rainfall and other conditions. Soils high in clay or organic matter require higher dos. ages than soil low in clay or organic matter to obtain equivalent herbicide performance. Moisture is required to activate the cheinical; best results occur if rainfall (or sprinkler irrigation) occurs within 2 weeks of application. "Karmex" may also be used to control emerged weeds. Results vary with rate applied and environmental conditions: best results are obtained on succulent weeds growing under cooditions of high humidity and temperatures of 70'F or higher. Additionof a surfactant such as Du Pont Surfactant WK to the spray(where recommended) increases contact effects of "Karmex". Since the effect of "Karmex" varies with soils. uniformityof application. and environmental conditions. it is suggested that growers limittheir first use to small areas. Observe all cautions and limitations on labeling of all products used in mixtures.

weeds are present. apply 2 to 3 lbs. per acre in February or March. Other Areas Where AlfalfaBecomes Winter Dormant: Use 1t/a to 3 lbs. per acre(lt/a to 2 lbs. per acre East of Appalachian Mountains), Apply in March or early April. but before spring growth begins. ARTICHOKECalifornia: Apply 2 to 4 lbs. per acre in late fall or early winter after the last cultivation. Applybefore weeds germinate or to emerging seedlings. Direct spray to cover the area between the rows and at the base of artichoke plants. keeping contact with crop plants at a minimum. ASPARAGUS: Apply as a band or broadcast treatment. Do not apply to young plants during the first growing season (except as noted below), nor to newly seeded asparagus. nor on plants with exposed roots as severe injury may result. Established Plantings: On light sandy soils and other soils low in clay or organic matter. apply 1 to 21bs. per acre. On soils high in clay or organic matter, use 2 to 4 lbs. per acre. Two applications may be used: the first application should be made before weeds become established but no earlier than 4 weeks before spear emergence and no later than the early cutting period (if weeds are controlled into the cutting period by cultural practices. application may be delayed until immediately after the last cultivation); a second appli ~ cation may be made immediately followingcompletion of harvest provided rainfall is expected. When two applications are used in one season, do not exceed 3 lbs. per acre per application. In Washington (irrigated, crop). apply only a single treatment of 4 lbs. per acre in late November or December. Newly Planted Crowns-California (San Joaquin Delta): Make a single application of 2 to 4 lbs. per acre on soils high in clay or organic matter: use the lower rate on clay loams and the higher rate on peat soils. Do not " use on soils containing less than 2oo organic matter. Soil must be settled by rainfall or irrigation Prior to treatment. Do not treat crowns planted to a depth of less than 2". BARLEY,WINTER(DrillPlanted)-Western Oregon and Western Washington: Make a single application of 1t/a to 2 lbs. per acre as soon as possible after planting but before emergence of barley. Do not replant treated areas to any crop within 1 year after last application as injuryto subsequent crops may result. BERMUDAGRASS PASTURES (Newly Sprigged): Apply 1 to 3 lbs. after planting and before emer gence of bermudagrass or weeds. Alternatively. for control of enterged annual weeds up to 4" in height. apply t/a to 1 lb. per acre: add 1 pt. Surfactant WK per 25 gals. of spray. If bermudagrass has emerged at time of treatment, temporary burn of exposed plant parts may occur. Plant sprigs (stolons) 2" deep in a well prepared seed bed: do not treat areas where sprigs are planted less than 2" deep as crop injurymay result. Do not graze or feed foliage from treated areas to livestock within 70 days after application. BIRDSFOOT TREFOIL (Lotus)-Western Oregon: Treat only stands established for at least 1 year; do not apply to seedling trefoil as injury may result. Make a single application of 2 lbs. per acre when trefoil is dormant (October 15 to December 15). Do not replant treated areas to any crop within 1 year after last application as injury to subsequent crops may result. CORN (FIELD): Postemergence-Make a single application of '/e lb. per acre in combination with non pressure nitrogen solution. If nitrogen solution is not used, apply 1 lb. per acre; add 1 pt. Surfactant WK per 25 gals. of spray. Apply as a directed spray when corn is at least 20" high and weeds are no taller than 3". DO NOT APPLY OVER TOP OF CORN.

Preemergence-Arkansas, Louisiana, Mississippi and Tennessee: Make a single application of a/a to 1 lb. per acre as a broadcast or band treatment after planting but before corn emerges. Plant corn at least lt/a" deep. Do not replant treated areas to crops other than corn or cotton within4 months followingband treat. ment and 6 months following broadcast treatment as crop injury may result. COTTON: -Karmex". alone or as recommended combinations. may be applied as preplant, preerner. gence. early postemergence. and/or lay by treatments. However. during a single crop season. do not exceed the followingamounts of "Karmex" per acre as injuryto subsequent crops may result: 1 lb. on loamy sand; 1t/a lbs. on sandy loam; 2 lbs. on clay loam: 2a/e lbs. on clay. Qo not allow livestock to graze treated cotton. Preplant-Arizona and California: Use "Karmex" alone. or.apply as a separate operation followingpreplant broadcast treatment with -Treflanuo (incorporated according to directions on -Treflan" label). Apply "Karmex" as a broadcast spray after beds are formed, preirrigated, and final seed beds prepared. Prior to planting, drag off the tops of the beds and plant in moist soil not treated with -Karmex". Treated soil is returned to the bed after planting when irrigation furrows are reformed after cotton has emerged. If more than two furrowing out operations are made prior to lay by. or deep furrows are made early, weed control may be reduced in furrow bottoms. Use at the following rates: "Karmex" Alone: 1 to 2t/a lbs. per acre.

Colo<fide, Kansas, New Mexico and Oklahoma: On sand bluestem. side oats grarna and switchgrass, apply 2 to 3 lbs. per acre during the dormant period shortly before weed seedlings emerge. Do not apply after crop begins growth in the spring as crop injury may result. In fields where ash residues have accumulated from burning straw, use 3 Ibs'. per acre; spread unburned chaff or straw with a harrow or chopper before application. Western Oregon: On alta fescue. Astoria bentgrass. Highland bentgrass, Kentucky bluegrass (Merion blue. grass) and orchardgrass. apply 2 to 4 lbs. per acre between October 1 and November 15. In fields where ash residues have accumulated from burning straw. use 3 to 4 lbs. per acre; spread unburned chaff or straw with a harrowor chopper before application. Ifperennial velvetgrass (Holcus Ianafus) is a problem, use 4 lbs. per acre. for best results. apply as soon as possible after tall rains start. Established weeds (beyond 2 to 4 leaf stage) should be removed prior to treatment. Well established vigorous stands of spring planted alta fescue, Kentucky bluegrass and orchardgrass may be treated the followingfall provided the crop is planted before April 1 and treatment is not applied before October 15: use 2 lbs. per acre. Oregon: For use in newly planted bentgrass. Chewings fescue, Kentucky bluegrass. perennial ryegrass. orchardgrass and tall fescue. During planting operation, spray Aqua Nu Chart or Gro Safety (activated charcoal) as a 1" band on soil surface at rate of 300 lbs. per acre (broadcast basis; equivalent to 15 lbs. per acre of crop vrh ere row spacing is 20"). Mount nozzles to apply directly over seed rows to prevent crop injury. Followwith'Karmex" as a single broadcast spray at rate ol 2h to 3 lbs. per acre: apply as soon as possible after planting but before crops or weeds emerge and before rains or sprinkler irrigation. Fall or spring plant. ings may be treated; best results usually occur with early fall plantings. Treatment willnot control downy brome or wild oats. taes. uademark ot westraeo corp. f'tItez. trademark of tel United states inc. OATS (DrillPlanted): Do not replant treated areas to any crop within one year after last application as injury to subsequent crops may result. Spring Oats-Idaho, Eastern Oregon, Eastern Washington: Use in areas where average annual rainfall exceeds 16". Make a single application of 1 to li/a lbs. per acre after planting, either before or after oats emerge but within 6 weeks of planting. Best results are usually obtained when application is made 3 to 4 weeks after planting. Apply before weeds are 3" to 4" tall. Winter Oats and Mixtures with Peas or Vetch-Western Oregon and Western Washington: Make a single application of 1t/a to 2 lbs. per acre as soon as possible after planting but before emergence of the crop. PEPPERMINT-Pacific Northwest: Apply3 lbs. per acre just after the last cultivation in the spring prior to emergence of peppermint. Do not apply to nevrly planted (less than 1 year) nor to emerged peppermint as injury may result. SORGHUM (GRAIN)-Southwestern States: Apply t/e to '/a lb. per acre; add 1 pt. Surfactant WK per 25 gals. of spray. Apply as a directed postemergence broadcast or band spray after sorghum is 15" tall to control weeds 2" to 4" in height. DO NOT SPRAY OVER TOP OF SORGHUM. Use the lower rate on broad leaved weeds up to 2" tall; use the higher rate on grasses up to 2" and broad!eaved weeds up to 4" tall. When the lower rate is used. a second application may be made if needed provided the amount applied in one crop year does not exceed t/a lb. per acre. Treatment ofweeds under drought stress is usually ineffective. Do not replant treated areas to crops other than cotton or corn within 4 months following band treatment and 6 months following broadcast treatment as crop injury may result. SUGARCANE: To prevent possible crop injury on new cane varieties. tolerance to "Karmex" should be determined prior to adoption as field practice. Do not treat sugarcane growing on thinlycovered subsoils or rocky areas as uop injury may result. Temporary chlorosis of the crop may result from application over emerged cane; to minimize chlorosis, use directed postemergence sprays. Florida: Preemergence-For high organic soils. apply 2 to 4 lbs. per acre as a broadcast or band spray prior to weed emergence after planting or after harvesting plant crop(for zatoon crop). Postern ergence-Make 1 or 2 applications of 2 lbs. per acre as needed by directed spray inter row. Alternatively, for panicum control, make up to 3 applications of t/a to 1 lb. per acre as a directed spray after cane has emerged but before panicum exceeds 2" in height; add 1 qt. Surfactant WK per 100 gals. of spray. Adjust nozzles to spray beneath cane plants and between rows to cover weed foliage and to minimize contact of cane leaves with spray or drift. Oo not apply more than 6 lbs. total per acre between planting (or ratooning) and harvest. Hawaii and Puerto Rico: Apply 4 to 8 lbs. per acre as a broadcast spray prior to weed emergence after plant. ing or after harvesting plant crop(for ratoon crop). Asecond and third application of 2 to 4 lbs. per acre may be made as a broadcast spray over emerged cane or by directed spray inter row. Ifweeds are emerged, add a surfactant(such as Surfactant WK, "Osamul" 95 or "Sterox" SK) to the spray at the rate of 1 to 2qts. per 100 gals. and apply as a directed spray. DO NOT SPRAYOVER TOP OF CANE. Do not apply more than 3 treatments nor more than 10 lbs. (Puerto Rico) or 12 lbs. (Hawaii) total per acre between planting (or ratooning) and harvest. Treated areas may be planted to sugarcane or pineapp'le one year after last application. Louisiana: Use on plant cane seeded on fallowed ground. Make a single application of 3 to 3s/e lbs. per acre at either of the follovring times. Fall Treatment (August through October)-Treat a 2 ft. band over the row after planting of cane. but before weeds or cane emerge. Spring Treatment (January through April)-if shaving and off barring are practiced. treat a 2 ft. band over the row before weeds or cane emerge. wHEAT, wINTER (DrillPlanted): crop injury may result where severe winter stress. disease or insect damage follows application; winter sensitive varieties such as McDermid and Hyslop maybe less tolerant of "Karmex" than winter hardy varieties such as Gaines and Nugaines. Crap injurymay also result from failure to observe the following: Oo not use on sand or loamy sand soils. nor on gravelly or sandy foams low in organic matter (less than 1%), nor on thinly covered or exposed subsoil areas (clay knobs); do not treat wheat planted less than 1" deep; do not treat wheat where winter climatic conditions have caused "heaving" I ' 4 ~ I

A single application of 3 lbs. per acre in January or February willcontrol both winter and summer annuals in some areas, but the separate fall and spring schedule is preferred. Western Oregon and Western Washington-Blueberries, Caneberries and Gooseberries: Use same schedule as recommended for California. CITRUS: Use only under trees established in the grove forat least 1 year. Tiine application as indicated for specific areas. except application may be made any time of the year where spdnkler or flood irrigation can be timed to activate the herbicide. Established perennial weeds require other special control procedures. Do not apply under citrus trees that have been subjected to freezing within 6 months. Arizona (except Yuma area) and California (except Imperial and Coachella Valleys)-Oranges, Lemons and Grapefruit: Apply3 to 4 lbs. per acre shortly after grove has been laid up in final form (nontillage program) in late fallor early winter. Alternatively, apply 2 lbs. per acre in October or November and repeat at the same rate in March or April.Subsequent annual applications of 2 to 3 lbs. per acre willusually give adequate weed control. Florida-Oranges, Grapefruit, Tangelos and Tangerines: Make a single application of 4 to 8 lbs. per acre, or apply 3 to 4 lbs. per acre followed by the same rate 4 to 6 months later. On bearing citrus. apply any time when seasonal rains are expected; on nonbearing trees, apply when winter banks are pulled down. For control of guineagrass, loosestrife, maidencane, paragrass, primrose willowand seamyrtle in ditches adjacent to citrus groves. use 1 lb. per 1000 sq. ft. (40 lbs. per acre) in sufficient water (min. 4 gals. per 1000 sq. ft.) to provide thorough and uniform coverage. Apply in the spring before weed growth starts or after removal of vegetation. Repeat treatment on a spot basis to control hard to killspecies such as guineagrass. In bedded groves, do not treat water furrows between the beds as injury to the trees may result. Texas-Oranges and Grapefruit: Apply 2 to 4 lbs. per acre for annual weeds: use 4 to 6 lbs. per acre for control of johnsongrass seedlings. Best results accompany application in the spring; well established weeds should be eliminated by cultivation prior to treatment. GRAPES: Applyonly to established vineyards(at least 3 years old) as a band treatment to grape rows. Do not apply to vines with trunks less than lilz" in diameter as injury may result. On soils low in clay or organic matter (1 to 2%), severe plant injurymay result if heavy rainfall or more than one inch of irrigation occurs soon after treatment. This risk must be assumed by the user. East of the Rocky Mountains: On soils low in clay or organic matter (1 to 2%), apply 2 to 3 lbs. per acre: on soils high in clay or organic matter, apply 3 to 6 lbs. per acre. Applyin the spring just prior to germination and growth of annual weeds. West of the Rocky Mountains: Apply in November, December or January. Forinitial treatment. apply 3 to 4 lbs. per acre: subsequent annual applications of 2 lbs. per acre will usually give adequate weed control. New York and Pennsylvania-Perennial Grasses: Use only in established vineyards (at least 4 years old) for spot control of perennial grasses such as orchardgrass, quackgrass and ryegrass. Apply in the spring as a band treatment to ridged soil (2" to 4" high) under the trellis at the rate of 8 to 12 lbs. per acre. Band width should not exceed 30". Do not apply'more than once every 4 years. Use only on heavy soils such as loams, silt loams. clay loams. Do not use in areas where grape roots are shallow or exposed because ot high bed rock, poor drainage, or erosion as injury to grapes may result. MACADAMIANUTS-Hawaii: Use only under trees established in the orchard for at least 1 year.

Alkalinity,or other causes; do not apply after wheat has reached the "boot" stage of maturity: do not use with surfactants, or nitrogen solutiori. Do not replant treated areas to any other crop within 1 year after last treatment (except as noted) as injury to subsequent crops may result. Idaho. Oregon and Washingt'on-East of Cascade Range: Areas Where Average Annual Rainfall Exceeds 16 Inches: Make a single application of 1 to 1'h lbs. per acre. Fall Treatment: For early fall planted wheat (seeded before September 10), apply 3 to 6 weeks after planting but before weeds are 3" to 4" tall. Treatment after October 1 has generally given best results. Application should not be made after soil freezes in the fall. Wheat planted in late October should not be treated until the following spring. Spring Treatment: Apply as soon as wheat starts to grow in the spring. Treatment made prior to April 10 willusually give good results provided weed growth is less than 4" tall. Application later than May 1 may give poor results. Alternatrvel, make a single application of ~!i to 1 lb. "Karmex" plus ~/i lb. bromoxynil per acre as a tank mixture. either in the fall after wheat has emerged but before soil freezes or in the spring as soon as soil thaws: apply before weeds are 2" tall or across. Areas Where Average Annual Rainfall is 10 to 16 Inches: After wheat is planted in the fall, make a single application of 1 to 1~/i lbs. per acre when sufficient moisture is available to germinate wheat seed. Apply before soil freezes and before weeds are 2" tall. Application later than March 1 may give poor results. Note-If fail planted wheat fails to grow due to winter kill or adverse growing conditions after fall treatment. only'ields treated before November 1may be replanted to spring wheat, Spring wheat should not be planted before April 1. and only after deep discing and plowing to a depth of 4" to 6" prior to planting. Do not retreat field with a second application during the same crop year as injury to the crop may result. Oregon and Washington-West of Cascade Range: Make a single application of 1'/z to 2 lbs. per acre as soon as possible after planting: if wheat and weeds have emerged, apply before weeds are 3" to 4" tall. Alternatively, apply a tank mixture of "Karrnex" plus brornoxynil as detailed above for "East of Cascade Range". Other Areas: Make a single application in the spring as soon as wheat (fall planted) starts to grow and before weeds are 2" tall. Application later than May 1 may give poor results.

Do not treat trees planted in the bottom of irrigation furrows. nor trees grown under flat flood or basin irrigation, as injury to trees may result. Where complete weed con. trol to harvest is desired. additional weed control measures may be required during the growing season. BANANAS-NewPlantings: To control annual weeds, apply 1~/~ to 3 lbs. per acre after planting but before plants emerge. Do not apply to loose soil directly over the planting material. Established Plantings: For control of'annuals and for top kill of perennials such as bermudagrass. bird seed grass and guineagrass. apply 3 to 6 lbs. per acre plus 1 pt. Surfactant WK(or suitable equivalent) per 25 gals. of spray; avoid contact of banana plants with spray or drift as injury may result. When tall. dense weed growth is present, remove weed growth before a pplication. Ifapplication is made to soil free of weeds. omit the surfactant from the spray. Repeat treatment as needed, but do not apply more often than 6 week intervals nor more than a total of 12 lbs. per acre (broadcast basis) in a 12 month period. r NOTE: Do not replant treated areas to any crop within 2 years after last application as injury to sub sequent crops may result. except that sugarcane or pineapple may be planted one year after last application. BLUEBERRIES, CANEBERRIES AND GOOSEBERRIES: Use only. in fields which have been established for at least 1 year. Do not apply to berries interplanted with fruit trees; do not apply to plants whose roots are exposed as injury may result. Apply as a band treatment at base of canes or bushes; for spring application. apply before germination,and growth of annual weeds. Indiana. Michigan and Ohio-Blueberries: Apply 2 to 4 lbs. per acre in late spring; alternatively, apply 2 lbs. per acre in the fall and repeat at same rate in the spring.

PINEAPPLE-Hawaii: Apply 4 to 8 lbs. per acre as a broadcast spray just before or immediately after planting but prior to weed emergence. Use 4 lbs. per acre after harvesting plant crop (for ratoon crop). For plant crop only, a second and third broadcast or interspace application may be made prior to differentiation at the rate of 2 lbs. per acre at intervals of not less than 2 months. Additional applications to plant crop may be made as needed to interspace only using 2 lbs. per acre. Do not apply more than 3 broadcast sprays (maximum 12 lbs. per acre) prior to differentiation nor more than 16 lbs. total per acre per plant crop. Treated areas may be planted to pineapple or sugarcane 1 year atter last application. WALNUTS (English)-California: Use only under trees established in the orchard for at least 1 year. As an initial treatment, apply 3 to 5 lbs. per acre after the orchard has been laid up in final form (nontillage pro gram) in late tall or early winter; retreat annually with 2 to 3 lbs. per acre.

Applyafter planting but no later than 4 weeks prior to bulb emergence (usually late September or October). Do not replant treated areas to any crop within 1 year after last application as injury to subsequent crops may result. PLUMOSUS FERN-Florida: Hand weed and mow fern: then make a single application of 3 lbs. per acre within 3 to 5 days. Do not cultivate or disturb soil after application as crop injury may result. Treat only established stands at least 1 year old, TREE PLANTINGS-Colorado, Montana, Nebraska, North Dakota, South Dakota, Wyoming: Use only under established plantings (1 year or older) of American elm, caragana, cottonwood, Douglas fir. green ash, honeysuckle, Ponderosa pine, redcedar, Russian olive and Siberian elm. Use 2i/z to 5 lbs. per acre: apply as a band 4 ft. wide in the tree row (2 ft, on each side of row). For examp! e, 1 oz. "Karmex" (4 level tablespoonfuls) treats 135 ft. of tree row(2 ft. on each side of row) at the rate of 5 lbs. per acre. Apply as a directed spray in early spring before weeds emerge and before trees leaf out. Do not apply to foliage o( trees. nor under trees growing in low areas as injury to the trees may result. r r, >>>4.6>>i>> >> <<> ig4, g+) WL6449a<<~ '"-" ~"" <<',=i~R~PI'>> yg'+tvr+Q:~i';mQ;:sp>> NON-CROP WEED CONTROL "Karmex" is an effective herbicide for the control of many annual and perennial grasses and herbaceous weeds on non cropland areas where bare ground is desired. The degree of control and duration of effect will vary with the amount of chemical applied, soil texture, rainfall and other conditions. "Karmex" may be used as a preemergence treatment at any tiine of the year except when ground is frozen. provided adequate moisture is supplied by rainfall or artificialmeans to activate the herbicide. Best results are obtained ifapplication is made to the soil shortly before weed growthbegins. Ifdense growthis present. remove tops and spray the ground. Increased contact activity on established weeds may be obtained by the addition of Du Pont Surfactant WK at the rate of 2 qts. per 100 gals, of spray mixture. Apply as a drenching spray to actively growing weeds during warm weather when daily temperature willexceed 70'F. Except for sinall areas. use a fixed boom power sprayer properly calibrated to insure a constant rate of application. Mixproper amount of "Karmex" into volume of water necessary to obtain uniform coverage: if Surfactant WKis used. dilute with 10 parts of water and add as last ingredient to nearly full tank. Material must be kept in suspension at all times. Agitate by mechanical or hydraulic means in the spray tank: if by pass or return line is used, it should terminate at bottom of tank to minimize foaming. Openings in screens should be equal to or larger than 50 mesh. General Weed Control: To control most weeds for an extended period of time on non cropland such as util~ ity, highway, pipeline and railroad right of ways, petroleum tank farms. lumber/ards, storage areas, indus. trial plant sites, and around farm buildings-apply 5 to 20 lbs. per acre to control most annual weeds. Use 20 to 60 lbs. per acre for perennial weeds: additional treatment may be required where a longer period of control is desired or when hard to kill. deep rooted perennial weeds such as johnsongrass are present. In low rainfall areas, "Karmex" may not provide satisfactory control of deep rooted perennial weeds. For weed control on small areas. use one half cupful of "Karmex" per 100 sq. ft. for a dosage of approxi mately 501bs. per acre. Irrigation and Drainage Ditches: Apply 5 to 20 Ibs, per acre to control most annual weeds; use 20 to 60 lbs. , per acre to control both annual and perennial weeds. Apply only when water is not in the ditch. For irriga. tion ditches, apply during the non crop season, and when ditch is not in use. To minimize movement of "Karmex" with irrigation water (to avoid possible crop injury), it is essential that the herbicide be fixed in the soil by moisture. Apply before expected seasonal rainfall (if possible when soil in the ditch is still moist). Following treatment, if rainfall has not totaled at least 4 inches, fillditch with water and a'liow to stand for72 hours; drain off and waste remaining water before using ditch. Do not treat any ditch into i which roots of tr '"s '>r ct.".>>r d;" i'<<'J
