Refer to labels for herbicides which can be combined. Refer to labels for restrictions on herbicides which cannot be used where animals are grazing. ------------------------------------------------------------------------------- Trade Name and Rate (lbs. active Common Name ingredient/acre Remarks ------------------------------------------------------------------------------ 2,4-D 4 For control of annual and perennial (2,4-D) broadleaf weeds and some woody plants and vines. Apply in 100 gals. of water to obtain thorough wetting of foliage. Apply when weeds are activley growing. Do not apply near susceptible crops. Ammate 50 - 95 For control of annual grasses and (ammonium broadleaf weeds and woody perennials. sulfamate) Apply in 50-100 gals. of water and spray foliage until wet. Add a surfactant such as Dupont WK to improve wetting. Corrosive to equipment, therefore wash thoroughly after application. Some residual activity. Arsenal 0.5 - 1.5 Arsenal offers good residual control of (imazapyr) many grasses and broad leaf weeds. Avoid application on fence rows where desirable tree species coexist. Vines and most brambles are controlled but higher rates will be necessary. Residual activity may last for 1 to 2 years. Banvel 0.5 - 8.0 For control of many annual and perennial (dicamba) broadleaf weeds. Use lower rates for annuals and higher rates for perennials. Refer to label for specific rates for each weed species. May be tank mixed with 2,4-D or 2,4,5-T for improved control. Do not apply near sensitive crops. \p (cont'd) \b\pFoliage Applications - cont'd \p------------------------------------------------------------------------------ \p Rate (lbs. active \pCommon Name ingredient/acre Remarks \p------------------------------------------------------------------------------ Crossbow 1% - 1.5% spray Crossbow controls a number of woody brush (triclopyr and vine species with good tolerance for + 2,4-D) pasture grasses. In addition, many annual broadleaf species will be controlled. Annuals will be controlled with a 1% spray while perennials will require the 1.5% spray. Dowpon M 4 - 30 For control of annual and perennial (dalapon) grasses. Use lower rates on annuals and higher rates on perennials. Apply when grasses are actively growing and prior to flowering. Apply in sufficient water to thoroughly wet leaves. Use a surfactant to improve wetting of foliage and grass control. Gramoxone Super 0.5 - 1.0 For control of annual grasses and (paraquat) broadleaf weeds and top kill of perennial weeds. Apply when weeds are small for best results. Apply in 50-100 gals. of water per acre for thorough coverage. Add surfactant X-77 at rate of 8 oz. per 100 gals. Roundup 2 - 4 For control of annual and perennial (glyphosate) weeds. Allow 7-10 days after application before mowing or any tillage. Do not apply with aerial spray equipment. -------------------------------------------------------------------------------- \b \h 1 'Soil Applications (residual control)' \v \v \v SOIL APPLICATIONS (residual control) Foliage applications provide most rapid kill of existing vegetation and are often combined with or followed by a soil applied treatment to extend the period of control.

Use lower rates for annuals and higher rates for hard to kill perennials. Higher rates give longer residual control. Rainfall or irrigation is needed to move the chemical into the root zone of the weed. Do not apply near desirable trees or in areas where their roots may extend. hexazinone 2 - 12 See remarks for bromacil above. diuron 4 - 48 See remarks for bromacil above. karbutilate 2.4 - 30 See remarks for bromacil above. tebuthiuron 4 - 16 See remarks for bromacil above. sodium chlorate 1/5 - 350 See remarks for bromacil above. + + sodium metaborate 220 - 440 + + bromacil 7 - 14 prometon 10 - 60 See remarks for bromacil above. prometon 11 - 44 See remarks for bromacil above. + + simazine 1.5 - 6.5 + + sodium chlorate 87 - 348 + + sodium metaborate 109 - 436 -------------------------------------------------------------------------------
