Sulcotrione - How to use
It is suitable for broad-leaved weeds and some monocotyledonous weeds such as alfalfa, eggplant, solanum nigrum, sorghum, sophora japonica, crabgrass, bloodroot grass, ceylon, and wild grass. Post-emergence application with doses of 300-450 g/ha (for active ingredients) can control broad-leaved weeds and grass weeds. The high-dose (active ingredient) 900g/ha is also safe for corn, but when drought and low-lying water are present, the corn leaves will have a temporary discoloration and no effect on the weight of the corn. Under normal rotation conditions, it is safe for winter wheat, barley, winter canola, potatoes, beets and peas. It can be used alone, mixed or continuously to control corn weeds.
