Problems solved by technology

As early as 1963, Macdowall The study by et al. showed that O 3 It is the main pathogenic factor of tobacco climate spot, which has nothing to do with fungi, bacteria and viruses, O 3 There is a correlation between concentration and climate spot hazard; studies by Huang Lihua et al. have proved that tobacco climate spot is caused by O 3 caused by injury, but the climate spot will be induced by the low temperature factor; Wang Xuede et al. believe that the main cause of the disease in the smoking areas of Henan Province is SO 2 Some studies also believe that the occurrence of tobacco weather spot disease is related to leaf stoma

Abstract

The invention discloses a resistance inducer for preventing a tobacco weather fleck and a preparing method thereof. The resistance inducer comprises effective constituents prepared from, by mass, 71.00% to 78.00% of thiophanate methyl, 17.80% to 24.80% of monopotassium phosphate, 0.0004% to 0.0008% of heteroauxin, 0.0002% to 0.0006% of brassinolide, 0.12% to 0.16% of gibberellic acid, 1.86% to 2.26% of padding and 1.80% to 2.20% of assistants. The preparing method includes the steps of material dosing, preparation mixing and sealing storing. 500-1,500-fold liquid is sprayed to leaf surfaces in fields for 2 times to 3 times at the time 20 days after tobacco seedling recovering or in the resetting stage or the flourishing growth stage, growth and development of tobacco plants can be well promoted, the stress resistance and the disease and pest resistance of tobaccos can be remarkably improved, the good prevention and control effect on the tobacco weather fleck is achieved, and the prevention and control effect can be higher than 70%.

Description

technical field [0001] The invention belongs to the technical field of tobacco plant protection, and in particular relates to an inducer for preventing and treating tobacco weather spot disease and a preparation method thereof. Background technique [0002] Tobacco weather spot ( Tobaccoweatherfleck ) is a non-infectious disease caused by ozone in the atmosphere, etc., and it occurs in all tobacco-producing countries in the world and is becoming more and more serious. China's Yunnan, Henan, Fujian, Hubei, Hunan, Anhui, Guangdong, Guangxi and other provinces are severely endangered, and other provinces are also quite common. As early as 1963, Macdowall The study by et al. showed that O 3 It is the main pathogenic factor of tobacco climate spot, which has nothing to do with fungi, bacteria and viruses, O 3 There is a correlation between concentration and climate spot hazard; studies by Huang Lihua et al. have proved that tobacco climate spot is caused by O 3 caused by in...
