Abstract

The invention discloses a preparation method of botanical pesticide for preventing rice downy mildew, which comprises radix aconite, berb of marshpepper smartweed, ginger, lodgepole needieminer, tobacco, polyxins and chlorothalonil. 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 paddy rice grains 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 paddy rice is too high.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method for preventing and treating rice downy mildew. 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...
