Bactericidal composition containing penconazole and thiophonate-methyl

Abstract

The invention belongs to the field of agricultural bactericides, and provides a bactericidal composite comprising penconazole and thiophanate-methyl, wherein, the weight percentage of the penconazole and the thiophanate-methyl is 0.1-80: 15-80. In addition to effective components, other additives and carriers are added to be prepared into a suspending agent, a wettable powder and a water dispersible granule, which is applied to the disease control of fruit trees, melons and wheat, the bactericidal composite is characterized by curing and protection effects on crop pests, wide bactericidal spectrum, remarkable effect, extremely strong bactericidal power, low service cost and no damage to crops and environment.

Description

technical field [0001] The invention belongs to the technical field of pesticide sterilization, and relates to a bactericidal composition. The active ingredients are composed of penconazole and thiophanate-methyl, which are used for disease prevention and treatment of fruit trees, melons and wheat, and are especially suitable for pear black star disease, watermelon powdery mildew and wheat powdery mildew. Background technique [0002] Penconazole, a triazole highly active fungicide with systemic, therapeutic, protective, and eradicating effects, inhibits sterol demethylation, works during the germination and invasion of fungal spores, and has super strong systemic properties , High efficacy, safe to crops, long-lasting characteristics. [0003] Thiophanate-methyl is a broad-spectrum fungicide. Its mechanism of action is to interfere with the formation of hammerheads in mycelial division, thereby affecting bacterial division, and has protective and therapeutic effects. [0...

AI Technical Summary

Problems solved by technology

[0004] Pear tree scab, also known as pear scab, is the most important disease of pear trees and often causes serious losses. It can occur from the time of falling flowers to the mature period of fruit trees, and harms all green tissues on pear trees. In recent years, due to long-term use Low-efficiency pesticides such as mancozeb, zinc zinc, etc. have caused disease resistance to become more and more serious, not only increasing the cost, but also having no obvious effect. With the increase in resistance and damage area, pear tree planting areas in the north and south of my country have been growing year after year. cause an outbreak

[0005] Watermelon and wheat powdery mildew, due to the rapid transmission speed and wide host range, occur all year round, and are particularly prone to resistance. Common control agents such as chlorothalonil and mancozeb have no control effect when used alone, and cause disease resistance. serious increase in sex

[0006] The current mainstream method to prevent powdery mildew and scab is to introduce new active ingredients, but the cost of new ingredients is too high to be widely used
