Pyrimidine nucleoside antibiotic and hexaconazole compound bactericide

Abstract

The invention discloses a pyrimidine nucleoside antibiotic and hexaconazole compound bactericide, which belongs to the technical field of agricultural agents. The bactericide is characterized by comprising 0.1 to 50 percent of pyrimidine nucleoside antibiotic and 0.1 to 70 percent of hexaconazole. By compounding the pyrimidine nucleoside antibiotic and the hexaconazole, the bactericide has good preventing and controlling effect, and the preventing and controlling rate of the bactericide can reach over 97 percent through field test; the bactericide has strong persistence, and the preventing and controlling rate of the bactericide can reach over 92 percent in 14 days after preventing and controlling banded sclerotial blight of rice and wheat; and the production cost is low and is reduced by over 50 percent compared with singly used pyrimidine nucleoside antibiotic.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pyrimidine nucleoside antibiotic and hexaconazole compound fungicide which can be used for preventing and treating crop diseases such as rice sheath blight and wheat sheath blight. Background technique [0002] Rice sheath blight is an important disease that often occurs in rice. It occurs seriously in rice areas south of the Yangtze River. It damages rice leaves and leaf sheaths and causes early yellowing and death of leaves. Thousand-grain weight decreased, thereby affecting rice yield. Rice sheath blight can occur throughout the rice growth period, and the incidence is most severe in the Yangtze River Basin from July to September. The control of rice sheath blight in my country mainly uses Jinggangmycin, triadimefon, Hesuining, Daofengling, etc. to spray before or at the beginning of the disease. However, the common defect of single use of this type of fungi...
