Problems solved by technology

[0002] At present, cotton blight and verticillium wilt are cancers of cotton, which can reduce cotton production by 40%-60%, and severely diseased fields can cause crop failure. Although there are dozens of pesticides for the prevention and control of cotton blight and verticillium wilt, the annual investment is huge manpower and material resources, but the effect is not very obvious, and some pesticides do not even have any effect, so that cotton farmers invest a lot in the prevention and treatment of cotton blight and verticillium wilt, but the effect is small, which not only reduces cotton production, but also increases planting costs

Embodiment Construction

[0012] A method for preventing and treating cotton fusarium wilt. Before sowing cotton seeds, mix 600 times of 50% carbendazim with water, soak the cotton seeds in the carbendazim solution for 8 hours, then fish out the cotton seeds for sowing, and sow the cotton fields. Before applying 30kg of potassium sulfate with a content of 25% per mu, 100kg of ammonium bicarbonate, and 1500kg of farmyard manure, the sowing time of cotton seeds was 3-10 days later than the normal sowing time.

[0013] Take North China as an example: the normal sowing time is April 20-25 every year, and the sowing time using this method is: the cotton field where the general disease occurs is from April 28 to May 1; the cotton field where the serious disease occurs is From May 1st to May 5th. Other conditions of sowing are the same as normal sowing conditions.

Abstract

The invention relates to a process for effectively prevention and cure for cotton chloranemia which includes, adding cotton seeds with 50% of multiple bacterium and 600 times of water before sowing, steeping 8hrs, sowing the cotton seeds, the content of materials applied in each 1 / 15 of a hectare includes 25% of kalium sulphuricum 25-40kg, ammonium bicarbonate 80-150kg, and organic fertilizer 1000-2000kg.

Description

1. Technical field [0001] The invention relates to a method for preventing and controlling cotton fusarium wilt, which is a method capable of effectively preventing and controlling the generation and development of cotton fusarium wilt and verticillium wilt during the growing period. 2. Background technology [0002] At present, cotton blight and verticillium wilt are cancers of cotton, which can reduce cotton production by 40%-60%, and severely diseased fields can cause crop failure. Although there are dozens of pesticides for the prevention and control of cotton blight and verticillium wilt, the annual investment is huge Manpower and material resources, but the effect is not very obvious, and some pesticides do not even have any effect, so that cotton farmers invest a lot in the prevention and treatment of cotton blight and Verticillium wilt, but the results are small, which not only reduces cotton production, but also increases planting costs. It causes huge economic loss...
