Plant medicament for preventing and controlling rice bacterial leaf blight

Abstract

The invention relates to a plant medicament for preventing and controlling rice bacterial leaf blight. The plant medicament comprises the following raw materials of 2000 g of wintergreen barberry root, 2000 g of polygonum hydropiper, 5000 g of bead tree leaves, 500 g of copper sulfate, 100 g of sulfur, 3000 g of ammonia water and 3000 g of garlic. Ammonia water and copper sulfate (or sulfur) are proportionally taken and mixed into copper sulfate (or yellow ammonia liquor); wintergreen barberry root, polygonum hydropiper and bead tree leaves are taken and ground and then put into a large iron pot to be soaked for 10 minutes with 65 L of warm water, are boiled for 20 minutes with hard fire and then boiled for 15 minutes with slow fire before taking off flame; garlic is mashed into garlic spread, and then garlic spread is poured into the iron pot to be stirred for 15 minutes; and a liquid medicine is obtained after filtering, then fully mixed with synthetic copper sulfate and yellow ammonia liquor and evenly stirred to obtain a finished product.

Description

technical field [0001] The invention relates to a plant medicine, in particular to a plant medicine for preventing and treating rice bacterial blight. It belongs to the technical field of planting pesticides. Background technique [0002] Rice is a kind of Poaceae, monocotyledonous, self-pollinated herbaceous annual herb that likes temperature and humidity. According to the growth habit, rice can be divided into paddy rice and upland rice. Generally rice is divided into two types namely indica and japonica. Generally, indica rice originated in the subtropics and is grown in tropical and subtropical regions. Japonica rice is grown in temperate and cold regions. [0003] At present, people generally use high-concentration pesticide spraying to kill rice bacterial blight. Although the control effect is very good, the residual pesticide components in rice are too high, which will cause harm to human body and make human body Susceptible to various diseases, it is easy to cau...

AI Technical Summary

Problems solved by technology

It overcomes the shortcomings of using high-concentration pesticide spraying, although the control effect is very good, but the residual pesticide components in rice are too high, which will cause harm to the human body and make the human body susceptible to various diseases.
