Problems solved by technology

The variety of chemical control is relatively single. At present, there are mainly varieties such as 40% Sclerotin WP (Speth) and 40% Sclerotin King Copper WP (Red Spot) on the market. Since these varieties have been used for many years, Tobacco red spot disease has developed resistance to it, and the powder pollutes the environment

[0014] The preparation of example 1 19% hymexazol-copper aqua

[0015] formula:

[0016] Ammonium copper: 6%;

[0017] Hymexazol: 13%;

[0018] Water: fill up to 100%.

[0019] Preparation method: Weigh an appropriate amount of hymexazol and copper methazine by weight, put them into a mixing tank, add an appropriate amount of water and stir until the original drug is completely dissolved.

[0020] Example 2 Indoor formula screening report of 19% hymexazol aquacopper

[0021] In order to clarify the control effects of hymexazol and hymexazol and their mixed preparations on tobacco red spot disease, our factory conducted research on the important pathogenic bacteria of tobacco Indoor virulence of tobacco spot disease was determined. The test adopts the growth rate method to calculate the inhibitory medium concentration (EC50) of each single agent and mixed agent, and the co-toxicity coefficient of different proportion combinations, and evaluates the combined effect of different proportions. The test results are now reported.

Abstract

The invention relates to a composition preparation of cuaminosulfate for resisting tobacco rust, comprising cuaminosulfate, anilazine and water, wherein the weight proportioning range of the cuaminosulfate and the anilazine is 1:1-5, the optimal proportion is 1:2.17, and the form of the composition preparation is aqueous solution. The composition preparation of cuaminosulfate for resisting tobacco rust is used for preventing tobacco rust and has high efficiency, low toxicity, low cost and no environmental pollution.

Description

technical field [0001] The invention relates to tobacco pesticides, in particular to a combined agent of copper ammonia and hymexazol for resisting tobacco red spot disease. Background technique [0002] Tobacco is one of the important economic crops in my country. Tobacco is grown in 26 provinces in my country, among which Yunnan, Guizhou, Henan, Shandong, Anhui, Hunan, Hubei and other provinces have relatively large cultivation areas. All provinces in the middle and lower reaches of the Yangtze River have a certain planting area, and my country's tobacco production ranks first in the world. [0003] According to reports, there are more than 100 kinds of tobacco diseases in the world, and nearly 40 kinds have been recorded in my country. Among them, red spot disease is one of the most harmful diseases in tobacco production. The provinces severely affected by red spot disease are Shandong, Henan, Anhui, Heilongjiang, and Jilin; followed by Sichuan, Yunnan, Guizhou, Liaoning...
