Embodiment Construction
[0037] Example:
[0038] Take Guizhou Daoyuan Biotechnology Co., Ltd. to produce 12.5kg of the original drug of albendazole ultrafine powder with a mass fraction of 98.9%, and then take 2.5 kg of the original drug of azoxystrobin with a mass fraction of 98.21% produced by Jiangyin Suli Chemical Co., Ltd. As a base material, it is compounded into 15kg compound fungicide for preventing and controlling rice sheath blight.
[0039] The compound fungicide was used in a certain place in Guizhou, and achieved good results in the control of rice sheath blight.

The invention discloses a compound bactericide for preventing and treating rice sheath blight. The compound bactericide is prepared from albendazole and azoxystrobin as base materials according to a mass ratio of albendazole to azoxystrobin of 5: 1 to 1: 3. Preferably, a mass ratio of albendazole to azoxystrobin is 5: 1. The albendazole is submicron powder of a raw drug having a mass fraction of 98.9% and the azoxystrobin is a raw drug having a mass fraction of 98.21%. The two reaction base materials in the compound bactericide do not undergo a chemical reaction and produce obvious synergism or combined effects and thus the compound bactericide is safe in use and has good poisoning activity to different types of rice sheath blight fungi in the field, wherein the poisoning activity is obviously higher than that of an albendazole or azoxystrobin single agent. The compound bactericide is suitable for preventing and treating rice sheath blight in the vast rural areas.
Description
technical field [0001] The invention relates to fungicides, specifically, belongs to fungicides containing organic compounds, and furthermore, belongs to fungicides for preventing and treating rice sheath blight. technical background [0002] Rice sheath blight, also known as moire, is commonly known as flower foot stalk, rotten foot blast, eyebrow spot. It is caused by infection by Rhizoctonia solani, and it mostly occurs under high temperature and high humidity conditions. Sheath blight is one of the major diseases in rice production, which is a serious hazard in southern rice areas. The disease prevents the rice from heading, or there are more grains in the heading, and the grain weight decreases. [0003] Albendazole, Albendazole, is a highly efficient, safe, and broad-spectrum imidazole fungicide, which has significant control effects on various plant diseases and has a certain effect on increasing production; Azoxystrobin, is Methoxyacrylate (Strobilurin) fungicides...
