Abstract

The invention provides a pesticide composition, which contains two active components: fludioxonil and methoxyacrylate fungicides, wherein the methoxyacrylate fungicides are selected from the group consisting of enoxastrobin, enoxim strobstrobin, pyraclostrobin or pyraclostrobin. The pesticide composition is mainly used for preventing and treating fungal diseases such as potato early blight, black mole, tomato early blight, gray mold, soybean and wheat root rot, cucumber gray mold, rice bakanae disease, and corn stalk rot. . The composition of the present invention includes methoxyacrylate fungicides and phenylpyrrole fungicides, both of which have different mechanisms of action, do not have cross-resistance, can be synergistic, and can reduce the dosage of a single agent used alone; and the preparation process Simple, low cost, significant economic benefits.

Description

technical field [0001] The invention belongs to the field of pesticides. It relates to a bactericidal composition, in particular to a composition containing fludioxonil and methoxyacrylate fungicides. Background technique [0002] Methoxyacrylate (Strobilurin) fungicides have been the focus of Shenyang Research Institute of Chemical Industry Co., Ltd.'s research and development and marketing for many years. Shenyang Research Institute of Chemical Industry has successfully developed 5 strobilurin fungicides and obtained 4 single-dose patent authorizations, namely enoxastrobin (ZL98113756.3), enoxastrobin (ZL00110143.9), pyraclostrobin ( ZL200410021172.3), pyraclostrobin (ZL200510046515.6). [0003] The mechanism of action of strobilurin fungicides is through interaction with cytochrome bc 1 The combination of the complex inhibits the electron transfer of mitochondria, destroys the energy synthesis of pathogenic bacteria, and thus plays a bactericidal effect. With the cont...
