Pretilachlor 30%EC 95%TC Weed Killer

Application

Pretilachlor can control weeds such as Cyperus difformis, barnyard grass, duckweed, and shepherd’s purse in rice fields. It is a selective pre-emergence herbicide and a cell division inhibitor. Weeds absorb the herbicide through the lower and middle parts of the embryo axis and the coleoptile, interfering with protein synthesis and indirectly affecting the photosynthesis and respiration of the weeds. Generally, it is applied through soil treatment to control barnyard grass, duckweed, Cyperus difformis, motherwort, barnyard grass, water fern, and bulrush in rice fields, but it is less effective against perennial weeds. The recommended dosage is 4.5 to 5.3 g/100 m². For rice seedling fields or direct-seeded fields, use 15 to 17 mL of Pretilachlor 30% emulsion per 100 m², applied as a water spray or mixed with toxic soil. In southern or subtropical regions, use the lower limit of the dosage; in northern regions, testing should be conducted before application.Pretilachlor is a selective pre-emergence herbicide and a cell division inhibitor. It is used for soil treatment and can control barnyard grass, Cyperus difformis, barnyard grass, duckweed, and narrow-leaved cattail in rice fields. When used alone, it has poor selectivity for wet-seeded rice, but when used in combination with safener, it exhibits excellent selectivity for direct-seeded rice.
