Problems solved by technology

When the germs have infected the crops or the disease has generally occurred, the pesticides have been applied, and the crops have caused a certain loss. No application of any fungicide can make the diseased spots disappear, and the crops recover as before, which has caused a certain impact on the yield of the crops.
[0003] Nowadays, the demand and use of fungicides in agriculture are increasing, and the general fungicides with short efficacy and weak control ability cannot meet people's needs. In order to achieve the purpose of controlling crop diseases, the use of fungicides The number of sowing is increasing, which increases the cost of manpower and material resources, and also causes some pollution to the environment.

Abstract

The invention relates to a composite germicide composition for crops. The composite germicide composition comprises 10-30 parts of difenoconazole, and 70-90 parts of prochloraz-manganese chloride complex; the sum of parts by weight of the difenoconazole and the prochloraz-manganese chloride complex is 100 parts; besides, the composite germicide composition further comprises 2.0-6.0 parts of organic silicon synergistic agent. A composite germicide for crops prepared by use of the composite germicide composition comprises 71-85% of composite germicide composition, 8-20% of carrier and 7-9% of auxiliaries. The form of the composite germicide is wettable powder; the composite germicide is used for preventing and treating ustilaginoidea virens, rice blast, sheath blight and dendrobium candidum anthracnose. The germicide composition is high in efficacy, high in microbicidal efficacy and relatively low in harm to crops.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound fungicide composition for crops, and also relates to a compound fungicide containing the compound fungicide composition and its application. Background technique [0002] At present, the fungicides used in crop production are mainly for protection, treatment and eradication. Applying pesticides before the pathogens infect the crops protects the crops from the infection of the pathogens, and applying the pesticides after the pathogens have already infected the crops inhibits the growth of the pathogens or kills them. Germs. When the pathogens have infected the crops or the diseases have generally occurred, the pesticides have caused a certain loss to the crops, and the application of any fungicides will not make the diseased spots disappear, and the crops will recover as before, which will have a certain impact on the yield of the crops. [0003] Nowadays, the demand and use ...
