Bactericide agent composition containing propiconazol effective component and use thereof

Abstract

The invention discloses bactericidal agent compound which contains effective composition of propiconazole and can be applied in the prevention and cure of leaf spot which is hard to prevent and cure in agriculture and the application of the bactericidal agent compound. Composition A of propiconazole and composition B of imazalil are combined, and the mass ratio of the bactericidal agent compound is A:B=50-1:1-50. Auxiliary material is also included in the application and remixing of the compound, the composition A, the composition B and the auxiliary material are mixed to produce creaming agent, aqueous emulsion and suspending agent, two or more of the above are chosen as auxiliary material which is not limited within the above agents in the remixing. The compound is characterized in that by three times of applying the double bactericidal agent compound, the prevention and cure effect is at least 90 percent and at most 98 percent seven days after the last application of the compound. The compound is mainly applied for bananas and can also be applied for crops such as mandarin trees, wheat and the like, and has good prevention and cure effect for blue mold and green mold of mandarin trees, wheat sharp eyespot, root rot, powdery mildew and rust of wheat. The consumption of effect composition is decreased, costs are reduced, the occurrence of the drug resistance of bacteria is retarded, and environment pollution is decreased.

Description

technical field

[0001] The invention relates to a pesticide fungicide composition and its application, in particular to a fungicide composition containing the active ingredient propiconazole and its application which can prevent and cure leaf spot disease which is difficult to control in agriculture. Background technique

[0002] At present, human beings attach great importance to environmental problems, and put forward higher requirements for the toxicity of pesticides and the environment. Highly toxic organophosphorus pesticides are gradually eliminated due to toxicity and environmental problems. In recent decades, many new types of high-efficiency, high-efficiency, and Low-toxic fungicides are used to replace highly toxic organophosphorus pesticides. There are many types and formulations of pesticides in my country, some of which cause serious pollution to the ecological environment, and the effective utilization rate of plants is low. The pesticide residues last for a long...
