[0015] The preparation of example 1 48% copper ammonia and propamocarb anti-tobacco black shank combination agent water

[0016] formula:

[0017] Propamocarb: 25%;

[0018] Ammonium copper: 23%;

[0019] Water: fill up to 100%.

[0020] Preparation method: Weigh propamocarb and copper ammonia copper by weight, put them into a mixing tank, add appropriate amount of water and stir until the original medicine is completely dissolved.

example 2

[0021] Example 2 Indoor formula screening report of 48% propamocarb·copper aqua

[0022] In order to clarify the control effect of propamocarb and propamocarb and their mixed preparations on tobacco black shank, our factory tested 48% downy mildew · methamine The indoor toxicity of copper water agent to tobacco black shank, an important pathogenic bacterium of tobacco, was determined by the growth rate method. After indoor screening, the best ratio was selected to be propamocarb: methmocopper 25:23, and the co-toxicity coefficient could reach 264. The test results showed that the mixture of methmocarb and propamocarb had obvious synergistic effects on tobacco black shank Effect, the test situation is reported as follows:

Abstract

The invention relates to a composition preparation of cuaminosulfate and propamocarb for resisting tobacco black shank, comprising cuaminosulfate, propamocarb and water, wherein the proportional range of the cuaminosulfate and the propamocarb is 1:1-2, the optimal proportion is 1:1.09, and the form of the composition preparation is aqueous solution. The composition preparation of cuaminosulfate and propamocarb for resisting tobacco black shank is used for preventing tobacco black shank and high efficiency, low toxicity, low residual and no environmental pollution.

Description

technical field [0001] The invention designs a pesticide, in particular to a combined agent of copper ammonia and propamocarb for resisting tobacco black shank. 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. 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. Tobacco black shank (Phytophthoranicotiana Breda de Haan) is a devastating disease of tobacco, and it is also one of the most serious diseases in the world's tobacco production. and seriously. In recent years, due to the expansion of the area of ​​contin...
