characters: the white solid.
dissolution: 20 ° C solubility (mg / L): 72.3 in water (pH 5), 1050 (pH7), 6536 (9-11), 13.9 acetonitrile, acetone 26.4, 2.1 methanol, toluene 1. 8, less than 0.2 n-hexane, ethyl acetate 13.0, 65.9 dichloromethane.
purposes: for the main control barnyardgrass, broadleaf weeds and Cyperaceae weeds. Because of the rapid metabolism in rice plants without poison, it is of rice security. Rice emergence application, use a dose of 8 ~ 25 g (a.i.) / ha. If used together with the auxiliaries will be a lower dosage. 20 ~ 25 g (a.i.) / ha application to effectively control barnyardgrass, North Water hair flowers, profiled Cyperaceae, purple amaranth water, eyes of vegetables, flowers Lin, OU Ze and diarrhea. Its barnyardgrass and Cyperaceae activity than bensulfuron, if they mix, synergistic obvious mix, even by water leaching in low temperature circumstances, weeding effect remains stable. Preparation or
Source: Malononitrile as starting materials, and the original three methyl formate reaction with hydrazine A condensation system in the intermediate pyrazole amines, with the reaction of sodium azide by methylation, diazotization, sulfonyl, amine, and the last amino acid pyrimidine condensation of benzene, a handle that.
Note: Mechanism; With other sulfonylurea herbicide, is acetolactate synthase (ALS) inhibitors. Weeds root and leaf through recruiting, in vivo transduction, or stop the growth of weeds, Leaf wilting, then withered.
