e0“In 1985, when weed densities were low (169 plants/m 2 in untreated control), imazaquin applied at 0.07 kg ai/ha early preplant controlled over 90% of all weeds before no-till planting of soybeans.”

Other claims from this paper (12)
- Intervention effect Adding metolachlor to imazaquin controlled at least 95% of grass weeds in the higher density years.
- Intervention effect Adding metolachlor to imazaquin controlled at least 83% of broadleaf weeds in the higher density years.
- Intervention effect Imazaquin plus metolachlor within a day after planting controlled less than 70% of emerged weeds.
- Observation Common lambsquarters was the most tolerant weed after postplant imazaquin plus metolachlor.
- Intervention effect Early preplant treatments controlled more weeds through the growing season than postplant treatments.
- Intervention effect Splitting herbicide treatment times generally did not increase weed control relative to single applications.
- Intervention effect Early preplant applications produced higher soybean densities than postplant applications.
- Intervention effect Early preplant applications produced taller soybeans than postplant applications at 30 days.
- Association Soybean yields increased as weed control increased.
- Intervention effect Early preplant treatments produced greater weed control than preemergence paraquat plus alachlor plus metribuzin.
- Intervention effect Early preplant treatments produced greater soybean yields than preemergence paraquat plus alachlor plus metribuzin.
- Observation The field corn bioassay detected no carryover of imazaquin residue.
