Problems solved by technology

[0004] At present, due to the long-term use of captan and fluoxastrobin, pathogenic bacteria have developed resistance, and due to the enhancement of drug resistance, the dosage of single doses has increased, which not only increases the cost of control, but also causes environmental pollution and crop safety problems. Therefore, there is an urgent need to find some fungicides that can delay the resistance of pathogenic bacteria and improve the control effect, especially when the fungicides have both protective and therapeutic effects, and can achieve the purpose of reasonable control

Abstract

The invention belongs to the field of pesticide compositions and particularly relates to a pesticide bactericidal composition containing captan and fluoxastrobin as main active ingredients, and application thereof. The active ingredients, captan and fluoxastrobin, in the pesticide bactericidal composition, have a weight ratio of 20:(1-1):8. In the above ratio range, the pesticide bactericidal composition has significant synergy for some crop diseases, the usage of pesticide active ingredients can be decreased, application cost of pesticides can be decreased, the prevention and treatment effectcan be improved, and the demand for zero increase of pesticides is met. The pesticide bactericidal composition is simple to prepare, low in cost, good in safety, and worthy of popularization and application in production.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and specifically relates to a pesticide fungicidal composition containing captan and fluoxastrobin and its application. Background technique [0002] Fluoxastrobin (Fluoxastrobin, CAS No. 193740-76-0) is a new type of methoxyacrylate fungicide, a new type of fungicide reported by Bayer Crop Science Co., Ltd., which is a mitochondrial respiration inhibitor , inhibits mitochondrial respiration by electron transfer between cytochrome b and C1. There are many types of fungicides that act on mitochondrial respiration, but the sites of action of methoxyacrylate compounds are different from those of previous fungicides. Strains resistant to amides and benzimidazoles are effective. Fluoxastrobin has a wide application period, and can provide very good protective and therapeutic effects in the early stage of fungal infection, such as spore germination, germ tube growth, or mycelium growth; it is es...
