Azoxystrobin and validamycin A composite bactericide

Abstract

The invention discloses an azoxystrobin and validamycin A composite bactericide, and belongs to the technical field of pesticides. The composite bactericide comprises 0.1-50% of azoxystrobin, and 0.5-60% of validamycin A. The azoxystrobin and validamycin A composite bactericide is reasonably composited, has a significant synergic effect, and good effects for preventing rice sheath blight disease, rice false smut and wheat sharp eyespot. Proved by a filed test, a control rate can be up to 97% above. A persistence property is strong; after 14 days of an application for preventing the rice sheath blight disease and the wheat sharp eyespot, the control rate can be up to 92% above. Production cost is low and reduced by 50% above, compared with a single use of the azoxystrobin.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound fungicide of azoxystrobin and Jinggangmycin A which can be used for preventing and treating crop diseases such as rice sheath blight, rice smut, wheat sheath blight and the like. 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 A, triadimefon, Hesuining, Daofengling, etc. to spray before or at the beginning of the disease. However, the common defect of single use of this type...
