Abstract

The invention discloses a resistance inducer for preventing and treating tobacco weather fleck and a preparation method thereof. The resistance inducer comprises amino-oligosaccharin, potassium oxalate, brassinolide, methyl jasmonate, beta-aminobutyric acid and benzothiadiazole. The resistance inducer prepared in the invention has good prevention and treatment effect on tobacco weather fleck and improves the quality of tobacco leaves without causing pollution to a soil environment.

Description

technical field [0001] The invention relates to the technical field of tobacco plant protection, in particular to an inducer for preventing and treating tobacco weather spot disease and a preparation method thereof. Background technique [0002] Tobacco climate spot disease is a non-infectious physiological disease caused by ozone-based air pollution. It is not contagious, but when it occurs seriously, it will cause greater harm to tobacco than other infectious diseases. [0003] In the prior art, in order to prevent or reduce the occurrence of tobacco weather spot disease, a large amount of chemical pesticides are often applied to tobacco plants, which not only affects the quality of tobacco leaves, but also causes serious pollution to the soil environment. [0004] Plant inducers improve plant stress resistance and disease resistance by regulating plant metabolism and activating plant immune system. At the same time, it stimulates a series of metabolic regulation systems i...
