A pharmaceutical composition for preventing and treating tobacco red spot disease and its suspension

Abstract

The invention discloses a composition for preventing and treating tobacco red spot disease, which comprises, in parts by weight: 0.5-10 parts of active ingredients and 0.001-0.1 parts of inducers; wherein the active ingredients include fluazinam and carvacrol in a weight ratio of 1 : 0.25~4. The present invention uses the combination of fluazinam and carvacrol, the components are reasonable, the treatment and protective effects are combined, the bactericidal effect is good, the addition of the inducer can improve the stress resistance of tobacco itself, and further improve the effect of preventing tobacco red spot disease and Use less. Since the combination of carvacrol and fluazinam has a synergistic effect and has an inducer, the frequency of medication is reduced and the cost of medication is low; the composition is composed of active ingredients with different mechanisms of action, and the sites of action are increased to overcome and delay bacterial resistance Produced; the active ingredients are all low-toxic agents, which are safe to non-target organisms and the environment, have no adverse harm to the human body, and meet the safety requirements of pesticide preparations.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pharmaceutical composition for preventing and treating tobacco red spot disease and a suspending agent thereof. Background technique [0002] Tobacco is one of the important economic crops in China. In my country's Henan, Shandong, Yunnan, Guizhou, Sichuan and other tobacco producing areas, the economic income brought by tobacco accounts for more than 50% of the entire agricultural income. The fiscal taxation of my country's tobacco industry is an important source of national fiscal revenue, ranking first among all walks of life in the country. As an important industry of the national economy, the tobacco industry has a very important position in the national economy. Today, my country is the world's largest producer of tobacco leaves, and tobacco production accounts for about 43% of the world's total output. [0003] Tobacco red spot disease (Alternaria alternata) is one of the imp...

AI Technical Summary

Problems solved by technology

Since the 1980s, the incidence and harm of red spot disease in major tobacco-producing areas in my country has become increasingly serious, and the output and quality of tobacco leaves have declined to a large extent, resulting in a great reduction in its industrial value.

At present, the domestic chemical agents for the prevention and treatment of the disease are mainly sclerotinia and polyoxin. Long-term large-scale use is easy to produce resistance. and tobacco leaf quality have a great influence
