Moisture in the __ £orm of rainfall or irrigati_on is required after application to move this product into the weed germination zone for p-ree,mergence weed control. The amount of moisture required depends on the soil moisture content at the time of application, soil type, and plant residues. Performance is improved when Il3 tb 3/4 inch of moisture is received within one week after applicatiori and prior to. weed emergence~ High intensity or excessive rainfall or irrigation after applicaticn may reduce preemergence weed control cn coarse soils~ READ AND CAREFULLY OBSERVE PRECAUTIONARY STATEMENTS AND ALL OTHER INFORMATION APPEARING ON THE LABELING OF ALL PRODUCTS USED IN MIXTURES.

) ) ) SO:tL TEX'I'tLRE Applicators should evaluate soil and weed conditions carefully to assure that they choose the lowest effective label rate.- The recommended use rates of this product and the other herbicides labeled for use in tank mixtures with this' product generally vary with soil texture. Unless soil texture is specifically-named, rate tables throughout this label refer to only three soil texture'groups: COARSE, MEDIUM and FINE. The following is· - complete listing of soil textures included ·in each of these three soil t-exture groups: SOIL TEXTURE GROUP 'SOIL TEXTURE snd, loamy sand, sandy loam loam, silt loam, silt, sandy clay loam COARSE MEDIUM FINE silty clay loam, clay loam, sandy clay, silty clay, clay Refer to the above table to determine the corresponding soil texture group for the soil to be treated. WEEDS,CONTROLLED When applied as directed under conditions described~ this product alone or in tank mixtures with other products lis-ted will_ control or reduce competition from the weeds indicated. Refer to the "DIRECTIONS FOR USE" section to determine rates for- each crop. Reduced control of emerged weeds may occur when weeds are under poor growing conditions such as from drought stress~ when application f-ollows recent mowing or when excessiv~ amounts o'f dust cover- the plants.

Ammonium sulfate shOUld be added to the water in the spray tank and completely dissolved prior to adding herbicide or surfactant. bo not. mix ammonium sulfate in fluid fertilizer -solutions. If .ammonium sulfate is· added directly to th,tspray tank, add slowly with agitation. Adding too qUickly may clog outlet 14,nes.
