- Intervention effect Hairy vetch residue lowered initial metolachlor concentration in two of three years.
- Intervention effect Hairy vetch residue increased metolachlor degradation rate in two of three years.
- Intervention effect Cover-crop treatment had little effect on atrazine concentration or degradation.
- Observation Annual grasses, mainly fall panicum, were the major weeds.
- Intervention effect Preemergence herbicides alone reduced grass emergence by 72 to 93% against no cover crop and no herbicide.
- Intervention effect Combining hairy vetch and preemergence herbicides provided 24 to 61% grass control compared with hairy vetch alone.
- Intervention effect The combination provided 23 to 52% grass control compared with herbicide alone.
- Intervention effect Metolachlor with hairy vetch delayed weed emergence compared with metolachlor without a cover crop.
- Intervention effect Metolachlor with hairy vetch reduced the metolachlor concentration needed to prevent weed emergence.
