Pesticide application method for rice

Abstract

The invention belongs to the filed of agriculture, and particularly relates to a pesticide application method for rice. The pesticide application method for rice is characterized by comprising the steps of carrying out pesticide application on leaf surfaces by two times, by acre: (1) applying the following liquid in a jointing period: mixed liquid consisting of a hexaconazole aqueous dispersant, 20wt% kasugamycin, calcium nitrate, 25wt% triadimefon, 50wt% bismerthiazol, 98wt% mepiquat chloride, and water; (2) applying the following liquid in a heading period: mixed liquid consisting of 30wt% hexaconazole aqueous dispersant, 50wt% carbendazim aqueous dispersant, 20wt% kasugamycin, 98wt% 4-iodophenoxyacetic acid, 35wt% ammonium molybdate, 21wt% boric acid, and water. The pesticide application method for rice disclosed by the invention carries out pesticide application on rice according to the growth rhythm of rice, has a good pesticide application effect, and saves pesticides; through the mixed utilization of various pesticides, the pesticide effect is improved, the usage amount of pesticides is reduced, the pesticide residues in crops are reduced, and the pollution is reduced.
