benefin (Balan DF)
Rate 1.2 to 1.5 lb ai/A (2 to 2.5 lb/A Balan DF)
Time Before planting clover, benefin must be incorporated into the top 2 to 3 inches of the seedbed.
Remarks Controls annual grasses and certain annual broadleaf weeds. Application rates are based on soil texture. Use the 2.5 lb/A rate on fine clay soils, use the lower 2 lb/A rate on coarse sandy soils.
Caution Weed control may vary if incorporation is delayed more than 4 hours after application. Do not apply benefin to soils that are subject to prolonged flooding, because poor weed control may result. In arid, irrigated areas, do not rotate to a small grain or other grass crop for 10 months to avoid crop injury due to herbicide carryover. See label for additional crop rotation restrictions.
Site of action Group 3: microtubule assembly inhibitor
Chemical family Dinitroaniline
EPTC (Eptam 7E or Eptam 20G)
Rate 2 to 4 lb ai/A (2.25 to 4.5 pints/A Eptam 7-E or 15 to 20 lb/A Eptam 20-G)
Time Apply to a clean, residue-free seedbed before final disking and harrowing. Immediately incorporate into the top 2 to 3 inches of soil to prevent losing the herbicide. Whenever possible, apply and incorporate in the same operation. Incorporation in two directions is recommended for heavy soils and perennial grass weed control. Clovers may be seeded any time after EPTC is incorporated into the soil.
Remarks Controls annual and perennial grasses (e.g., quackgrass and common and German velvetgrasses) and certain broadleaf weeds.
Caution Temporary crop stunting and sealing of the first leaves will occur if clover germination conditions are not optimum. Do not use if a grass or small-grain nurse crop is to be planted with the clover. Do not use on white clover.
Site of action Group 8: lipid synthesis inhibitor but not an ACCase inhibitor
Chemical family Thiocarbamate
