Abstract

The invention discloses a composite bactericide for preventing and treating sheath blight, and belongs to the pesticide field. The invention aims at providing the composite bactericide which has good effect on preventing and treating the sheath blight of wheat and maize. The technical field of the invention is that the composite bactericide for preventing and treating the sheath blight comprises jinggangmycin and an auxiliary agent, and the components and the weight ratios thereof are as follows: 25-30 part of the jinggangmycin, 15-20 parts of diniconazole, 45-50 parts of mancozeb and 4-6 parts of ethylicin. Compared with the prior art, the composite bactericide has significant advantages of better effect on preventing and treating the sheath blight of the wheat and the maize. The composite bactericide is used for preventing and treating the sheath blight of the wheat and the maize.

Description

Technical field: [0001] The invention relates to a pesticide, in particular to a compound fungicide for preventing and treating sheath blight. Background technique: [0002] Sheath blight is an important soil-borne disease of gramineous crops in my country, and the sheath blight fungus mainly enters the soil with crop stalks to survive winter and summer. In recent years, with the vigorous promotion of straw returning technology in my country, the amount of bacteria in the soil is increasing, and the disease is becoming more and more serious, which will inevitably pose a serious threat to the production of wheat and corn. According to the experimental surveys we set up in Xinxiang County and Huojia County, Xinxiang City, Henan Province in 2006 and 2007, the results showed that: with the increase of the amount of straw returned to the field and the number of years of returning to the field, the disease worsened, and the wheat and corn straw returned to the field and the Take ...
