Bactericidal pesticide composite with benthiavalicarb isopropyl and application of composite

Abstract

The invention discloses a benthiavalicarb isopropyl containing bactericidal pesticide composite and application of the composite, and aims at solving the problem that the drug resistance of plants is generated and is gradually poor in prevention and control effect on diseases as a traditional pesticide used for tobacco black shank, cucumber downy mildew and tomato late blight already is high in dose and used for long term. The bactericidal pesticide composite comprises benthiavalicarb isopropyl and aliette. The bactericidal pesticide composite disclosed by the invention can effectively reduce the application amount of single doses, reduce the production cost, enlarge the bactericidal spectrum and prolong the drug resistance of the plants through the compatibility of components, can be used for preventing and controlling crops (which include vegetables, fruit trees, Chinese herbal medicines, flowers, cotton, hemps, oil materials, and the like) pestilence and the downy mildew, can also be used for preventing and controlling the tobacco black shank, is obviously superior to the single doses of the two drug components, namely the benthiavalicarb isopropyl and the aliette, in effect and has a relatively high application prospect and a relatively high popularization value.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a bactericidal pesticide composition, specifically a bactericidal pesticide composition containing benthiazil and its application. Background technique [0002] Tobacco black shank is one of the main diseases that harm tobacco crops, which can often lead to a large reduction in tobacco production, or even crop failure. The pathogens of the disease survive the winter in the soil or manure in the residual body of the diseased plant with chlamydospores and hyphae. The pathogens can survive for more than 3 years and are the main source of primary infection. The disease is more likely to occur in high temperature and high humidity weather, especially the rainy weather is more likely to make the disease popular. At present, the medicaments for the prevention and treatment of tobacco black shank mainly include metalaxyl, metalaxyl mancozeb, propamocarb, etc. Due to the large doses and freque...

AI Technical Summary

Problems solved by technology

[0005] In summary, the existing methods for tobacco black shank, cucumber downy mildew, and tomato late blight have caused the plants to develop resistance due to large doses and long-term use, and the control effect on diseases is getting worse and worse.
