Problems solved by technology

[0004] Due to the long-term use of the above two agents alone, it is easy to lead to the generation of drug resistance of bacteria, resulting in a significant decline in drug efficacy, resulting in a large increase in dosage, shortened spraying cycle, and poor use effect, which increases costs. The use of a large number of pesticides makes the bacteria The resistance is more serious, and it also has a certain impact on the environment. The drug residues in agricultural products are also increasing, which affects the health and normal survival of humans and animals. The compound use of difenoconazole and krasstrobin is used to prevent and control crop diseases , has not been reported at home and abroad

Abstract

The invention discloses a bactericidal composition containing difenoconazole and kresoxim-methyl and a preparation method and applications thereof. The bactericidal composition is characterized by comprising difenoconazole and kresoxim-methyl and other assistants, wherein the weight ratio of the difenoconazole to the kresoxim-methyl is 1:1-1:80. The bactericidal composition provided by the invention can be used for prevention of fungal diseases of crops such as cereals and fruit trees, melons and vegetables, has characteristics of wide application range, low cost and good effect. The indoor pharmacodynamic tests prove that the bactericidal composition has obvious synergistic function.

Description

technical field [0001] The invention belongs to the field of fungicides and relates to a fungicide composition. Specifically, it relates to a bactericidal composition compounded with difenoconazole and kresoxim-methyl and the application of the bactericidal composition in agricultural production. Background technique [0002] Kresoxim-methyl, also known as (E)-2-methoxyimino-[2-(o-methylphenoxymethyl)phenyl]methyl acetate, is a high-efficiency, broad-spectrum, new Semi-systemic fungicide, which diffuses in gaseous form, can not only prevent the germination, elongation and invasion of germ tubes on the surface of leaves and fruits, and play a preventive and protective role; it can also penetrate the waxy layer and epidermis or enter through stomata In the body, it inhibits the growth of invading bacteria, shrinks mycelia, inhibits spore production, prevents spores that have been produced from germination, and achieves the effect of treatment and eradication. Kresoxim-methyl...
