Technical Field

The invention relates to the technical field of agriculture, in particular to a bactericidal insecticide-fertilizer composition and application thereof.

Background

The action mechanism of the fenoxanil bactericide is an inhibitor for melanin biosynthesis and capable of inhibiting activity of small columella ketone dehydrogenase, so that formation of the melanin of rice blast fungus is inhibited. The fenoxanil has good systemic property and excellent specific property.

The kresoxim-methyl is a new generation of high-tech bactericide product newly developed according to crop pathogenesis, is green and environment-friendly, can control and treat most diseases of ascomycetes and the like, has strong inhibiting effect on spore germination and growth of intraleaf mycelia, has protection, treatment and eradication activity, and has good permeation and local systemic activity and long lasting period. The kresoxim-methyl also has the obvious effects of changing soil environment and promoting the growth and development of plants, so that the crops can quickly recover growth, the kresoxim-methyl takes effect in three days, and the kresoxim-methyl can play a role after entering the crops, and has obvious effect. In addition, the kresoxim-methyl can play a positive physiological regulation role in crop production, can inhibit the generation of ethylene, help crops to reserve biological energy for a longer time to ensure maturity, can obviously improve the activity of nitroreductase of the crops, and can accelerate the formation of protein in resisting viruses when the crops are attacked by the viruses.

Although fenoxanil and kresoxim-methyl have the above characteristics, if fenoxanil or kresoxim-methyl is used alone continuously for a long time, resistance risks are easily generated and the risk of increase in the amount is easily increased, thereby increasing the cost and environmental load. In agricultural production, people also hope that one farming operation can realize fertilizer application and pesticide application, so that two operation steps in the field are combined into one, and thus, time, labor and force can be saved, and the agricultural production cost can be reduced.

Based on the bactericidal pesticide-fertilizer composition, the two procedures of fertilization and sterilization can be simultaneously completed by one-time application in wheat production, so that the condition that the prior pesticide application and fertilization cannot be simultaneously carried out is avoided, the time and labor are saved, the production efficiency is improved, and the yield of wheat is remarkably increased.
