Abstract

The invention discloses a biological compound agent for preventing and controlling fungus diseases, for example, rice sheath blight disease, in particular to a difenoconazole and validamycin A wettable powder. 20 to 80 mg of difenoconazole, 40 to 160 mg of validamycin, wetting agent, dispersant and filling agent are contained in the powder per gram. The difenoconazole is an efficient systemic fungicide, and the validamycin is biological antibiotics, therefore, the difenoconazole and validamycin A wettable powder has the dual effects of bacteria resistance and sterilization. The control effect of the difenoconazole and validamycin A wettable powder to the rice sheath blight disease reaches 76.2 to 91.7 percent through field test by the relevant unit, and compared with the single validamycin, the difenoconazole and validamycin A wettable powder has the advantages that the control effect against the rice sheath blight disease is increased by 12.3 to 20.5 percent, and the effect of increase in yield is improved by 13.6 percent.

Description

technical field [0001] The invention relates to a biological compound agent for preventing and treating fungal diseases such as rice sheath blight, in particular to a wettable powder compounded by difenoconazole and Jinggangmycin A. Background technique [0002] Jinggangmycin is a traditional pesticide used to control rice sheath blight, which has been used alone for more than 30 years. The sheath blight bacteria have developed resistance to it, and the disease control effect has declined. The amount and frequency of use of Jinggangmycin in field control have continued to increase , the continuous single use of Jinggangmycin to control rice sheath blight can no longer meet the needs of modern agricultural production. Contents of the invention [0003] The object of the present invention is to provide a difenoconazole Jinggangmycin A wettable powder for preventing and treating fungal diseases such as rice sheath blight in order to overcome the deficiency of using Jinggangmy...
