US rice pesticide trends
Clomazone and propanil remain the most widely used herbicides on US rice crops, according to the 2006 survey by the USDA. Some 50% of the rice area surveyed last year was treated with clomazone and 46% with propanil. These figures compare with 32% and 62%, respectively, when rice pesticide usage was last surveyed by the USDA in 2000. Quinclorac usage was largely unchanged at 24% (25% in 2000).
