Bactericidal composition containing bromothalonil and pentachloronitrobenzene

Abstract

The invention relates to a bactericidal composition of bromothalonil and pentachloronitrobenzene, and belongs to the technical field of chemical industry. The bactericidal composition containing bromothalonil and pentachloronitrobenzene is provided, the effective components of the bactericidal composition is bromothalonil and pentachloronitrobenzene, wherein the weight ratio of bromothalonil to pentachloronitrobenzene is 1:79-79:1, and the optimal scheme is that the weight ratio of bromothalonil to pentachloronitrobenzene is 1:60-60:1. The pesticide composition can be formulated as micro-emulsion and water emulsion. The effective components of the bactericidal composition, bromothalonil and pentachloronitrobenzene, account for 5%-80% of a compound bactericidal composition. According to theformulation, different action mechanisms are utilized, advantages are complementary, the bactericidal spectrum is widened, the synergistic effect is obvious, the emergence of resistance is effectively delayed, and the bactericidal composition has the advantages of high efficiency, low toxicity and long efficacy duration, and has good preventive effects on crop stand blight, anthrax and other diseases. The bactericidal composition has less pollution to the environment, the use is safe, crops are protected to increase production and income, and economic benefits of farmers are increased.

Description

technical field [0001] The invention relates to the technical field of pesticide control, in particular to a bactericidal composition of bromothalonil and pentachloronitrobenzene. Background technique [0002] Since the reform and opening up, my country's agriculture has developed rapidly, and the demand for pesticides has also increased year by year. However, the diseases of crops are mostly caused by a combination of multiple diseases. The effect of using a single pesticide is not good, and it is easy to produce resistance, resulting in a decline in efficacy. The mixed use of multiple pesticides often leads to antagonism of active ingredients, complex configuration, heavy workload, and large dosage. On the other hand, the use of organic solvents in pesticides is increasingly restricted. It is an inevitable trend in the development of pesticides. The dosage forms of pesticides need to be constantly updated, so as to promote the development of pesticides along the direction of...

AI Technical Summary

Problems solved by technology

The use of compound fungicidal composition can effectively delay the emergence of disease resistance and reduce the frequency and amount of pesticide use. The technical personnel of scientific research institutes and enterprises have conducted in-depth research on the formula screening of bromothalonil and pentachloronitrobenzene. It is found that the combination of bromothalonil and pentachloronitrobenzene has a synergistic effect on the prevention and control of various diseases in a certain proportion range. The microemulsion and water emulsion of bromothalonil and pentachloronitrobenzene composition have been developed, although some achievements have been made. progress, but there are still technical difficulties that have not been overcome in practical application
