Other claims from this paper (7)
- Intervention effect Propanil at 3.3 kg/ha with carbaryl at 0.1 to 0.3 kg ai/ha controlled propanil-resistant barnyardgrass in rice at least 90% when applied at the two-leaf stage.
- Intervention effect Propanil at 3.3 kg/ha with carbaryl at 0.1 to 0.3 kg ai/ha showed no rice yield reduction when applied at the two-leaf stage.
- Intervention effect Applications repeated at the four-leaf stage also controlled propanil-resistant barnyardgrass in rice.
- Observation Rice injury was 66% with 0.3 kg/ha carbaryl in one of two years.
- Intervention effect Repeated applications at the four-leaf stage reduced rice yield.
- Intervention effect Control of resistant barnyardgrass by commercial propanil plus carbaryl and propanil plus molinate formulations was lower with a single application than with repeat applications.
- Intervention effect Propanil plus quinclorac, propanil plus pendimethalin and propanil plus molinate plus pendimethalin controlled resistant barnyardgrass in rice with one application at the two-leaf stage.
