Preparation method of botanical pesticide for preventing cotton anthracnose

Abstract

The invention discloses a preparation method of botanical pesticide for preventing cotton anthracnose, which comprises tea seed cakes, rhizoma coptidis, tobacco, pagoda tree leaves, bead leaves, gingers and one-clove garlic. The botanical pesticide has the advantages that the formulation and the preparation method are simple, the cost of raw material is low, the compatibility is simple, the prevention effect is good, and various beneficial microorganism and organic fertilizer contained in the botanical pesticide can also achieve the effect of fertilizer increasing, promote cotton to be full and have heavy weight. The botanical pesticide not only has the effect of increasing the output, but also effectively solves the defect that the residual pesticide ingredient in cotton is too high.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method for preventing and treating cotton anthracnose. It belongs to the technical field of planting pesticides. Background technique [0002] Cotton, with milky white flowers, turns dark red shortly after flowering and then withers, leaving green cotton bolls with cottonseeds inside, and the fluff on the cottonseeds grows from the skin of the cottonseeds. When the bolls mature, they split open, exposing the soft fibers. The fibers are white or white with yellow, about 2-4 cm long, containing about 87-90% cellulose, 5-8% water, and 4-6% other substances. Cotton is one of the most important crops in the world, with high output and low production cost, which makes the price of cotton products relatively low. Cotton fiber can be made into fabrics of various specifications, from light and transparent voile to thick canvas and thick velveteen, suitable for making all kinds of c...

Problems solved by technology

[0003] At present, people generally use high-concentration pesticide spraying to kill cotton angular spot disease. Although the control effect is very good, the residual pesticide components in cotton are too high, which will cause harm to human body and make people's body vulnerable. Suffering from various diseases can easily lead to a decline in the immunity of various functions of the human body. Long-term wearing of cotton products with pesticide residues is more likely to cause various diseases.
