Other claims from this paper (9)
- Intervention effect Giant foxtail control increased linearly as the nicosulfuron rate increased with no additive or with urea ammonium nitrate (1988 adjuvant study).
- Intervention effect Petroleum oil concentrate, nonionic surfactant, and combinations of either with urea ammonium nitrate, applied with nicosulfuron, increased giant foxtail control to 90% or greater regardless of rate in both years.
- Intervention effect Nicosulfuron at all rates, with no additive and with all additives, controlled 93% or more of redroot pigweed in both years.
- Intervention effect Nicosulfuron at all rates, with no additive and with all additives, controlled 93% or more of Pennsylvania smartweed in both years.
- Association Corn grain yield was related to the level of giant foxtail control.
- Intervention effect In the rate by corn growth stage study, giant foxtail control was 90% or greater regardless of nicosulfuron rate or application stage in both years.
- Intervention effect In the rate by corn growth stage study, Pennsylvania smartweed control was 90% or greater regardless of nicosulfuron rate or application stage in both years.
- Intervention effect Corn grain yield was 8 to 12% lower with nicosulfuron applied at the V7 growth stage than at the V3 or V5 growth stage.
- Association Corn grain yield was related more to the duration of weed competition than to the level of weed control.
