| Abstract: | Soybean weed control experiments conducted in 2003 and 2004 indicated that an acetochlor 50% microemulsion at or above 600 g a,i./ha provided good control of grass and small-seeded broadleaf weeds, with weed plant reductions greater than 80% and 55-d fresh weight reductions greater than 85%. Soybean yields were not affected at all rates tested. |
