The plant agent consists of 5,000 grams of endospermum chinense benth leaf, 5,000 grams of nux vomica, 5,000 grams of pine needle, 5,000 grams of kusnezoff monkshood root, 3,000 grams of artemisia annua, 2,000 grams of towel gourd leaf and 10,000 grams of garlic bulb. The plant agent is prepared by the following steps of: mashing and combining the endospermum chinense benth leaf, the nux vomica, the pine needle, the kusnezoff monkshood root, the artemisia annua and the towel gourd leaf in a ratio, putting the mixture into a big iron pot, adding 200 kilograms of warm water to soak the mixture for 20 minutes, boiling over big fire for 30 minutes, boiling over soft fire for 15 minutes, and stopping the fire; and mashing all garlic, adding the mashed garlic into the decocted medicinal liquid, fully stirring for 30 minutes, and filtering.

Description

technical field [0001] The invention relates to a plant medicine, in particular to a plant medicine for preventing and treating cotton angular leaf spot. 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 clo...

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, and wearing cotton products with pesticide residues for a long time is more likely to cause various cancers
