( ( -4- General Information Duet is a selective herbicide which is mixed with water and applied as a preemergence treatment to control most annual grasses and certain broadleaf weeds in soybeans. Dry weather following a preemergence application· may reduce effectiveness. If weeds develop, a shallow cultivation (rotary hoe preferred) should be made after soybear. emergence while weeds are small enough for mechanical control. Where reference is made to weeds partially controlled, partial control can either mean erratic control from good to poor, or consitent control at a level below that generally considered acceptabl for commercial weed control. Prepare a good seed bed. Soybeans cannot be properly planted in cloddy or compacted soil and crop injury may result following j the preemergence application. Do not cultivate before soybean emergence, except as noted above, as weed control may be reduced and crop ir.jury may result. Precaution: Crop injury may occur following the use of Duet if heavy rainfall occurs soon after application. Thoroughly clean sprayer prior to use. Do not use a sprayer contaminated with any other materials, or crop damage or sprayer clogging may result. Mixing Instructions Mix Duet with water and apply as a spray. Fill the spray tank one-half to three-fourths full with water, add the proper amount ,,:> of Duet, then add the rest 'If the water. Provide sufficient ~ .. <".>< agitation during mixing and application to maintain a uniform r, ""'' emulsion.

Application Procedure~ Ground APplication: Apply in a minimum of 10 gals. of spray mixture per acre. Use sprayers that provide accurate and uni­ form application. Avoid overlapping, and shut off spray booms when starting, turning, slowing or stopping, or soybean injury may result. Rinse sprayer thoroughly with clean water immedi­ ately after use. Calculate the amount of herbicide needed for band treatment by the formula: band ,fidth in inches X row wl.dth in inches Do not apply aerially. broadcast rate per acre = amount needed per acre of field Chemigation: Do not apply this product through any type of irrigation system. Soybeans Apply Duet during planting (behind the planter) or after plant­ ing, but before weeds or soybeans emerge, using the appropriate rate from Table 1. To avoid crop injury, plant seed at least 1 3/4 inches deep on flat or raised seedbeds only. • IIIII • ., t • I. • I I • .. . · . • · . .. • • I I I I • • .. • ,.
