Compound Chinese herbal medicament preparation for controlling cotton verticillium wilt and production method thereof

Abstract

The invention discloses a compound Chinese herbal medicament preparation for controlling cotton verticillium wilt and a production method thereof, and belongs to the field of Chinese herbal medicament agricultural technologies. The compound Chinese herbal medicament preparation is prepared from the following raw materials in parts by weight: 10 to 40 parts of radix astragali, 10 to 20 parts of sophora flavescens, 10 to 20 parts of coptis root, 10 to 20 parts of baikal skullcap root, 5 to 11 parts of dandelion, 5 to 10 parts of radix bupleuri, 6 to 11 parts of fructus forsythiae, 10 to 15 parts of honeysuckle, 7 to 12.5 parts of dyers woad leaf and 5 to 10 parts of wrinkled gianthyssop herb. The compound Chinese herbal medicament preparation is prepared by the steps of decocting the raw materials, filtering, and performing vacuum concentration and sterile filing. The ingredients in the compound preparation have different roles as a monarch drug, a ministerial drug, an adjuvant drug and a conductant drug, prevention and treatment are combined together, and the drug effects are synergetic, so that the cotton immunity is enhanced, the effect of killing cotton verticillium wilt viruses is outstanding, and the preparation is low in production cost and long in drug effect without residues, and has no toxic or side effect on cotton and environment.

Description

technical field [0001] The invention relates to a compound Chinese herbal medicine preparation for preventing and treating cotton verticillium wilt and a production method thereof, belonging to the technical field of Chinese herbal medicine agriculture. Background technique [0002] Cotton Verticillium Wilt (Verticillium Wilt) is a soil-borne fungal disease, which has a wide range of distribution, severe damage, wide host range, multiple transmission routes, and long survival time. It has spread all over cotton in the United States, China, Russia, India, etc. The main producing area has become the first disease that harms cotton in the world, and because the ideal control method and prevention technology have not been found in production, it is called the cancer of cotton. Verticillium wilt of cotton in my country was introduced from the United States in 1935, and has continued to spread since then. Especially since the 1990s, due to changes in environmental conditions, larg...

AI Technical Summary

Problems solved by technology

[0004] Among cotton cultivars, most sea-island cotton varieties have high disease resistance to Verticillium wilt, and their disease resistance has a high and stable performance in different regions and between years, but after decades of genetic breeding practice It proves that it is difficult to obtain high-resistance and high-yielding upland cotton varieties with classical genetic breeding methods

Crop rotation is commonly used to prevent Verticillium wilt in foreign countries, but it is difficult to apply in my country due to the small amount of cultivated land per capita

Chemical control pollutes the environment, biological control costs are high and the control effect is not ideal
