Summer paddy rice bactericide and preparation method thereof

Abstract

The invention discloses a summer paddy rice bactericide, which comprises following components in parts by weight: 10 to 16 parts of validamycin, 20 to 22 parts of prochloraz, 8 to 11 parts of radix astragali, 6 to 10 parts of diatomite, 5 to 8 parts of light calcium carbonate, 2 to 4 parts of sodium polyacrylate, 4 to 8 parts of sodium lignosulfonate, 1 to 3 parts of methyl pentanol, 2 to 6 partsof polyacrylamide, 3 to 5 parts of sodium acetate, and 4 to 7 parts of magnesium chloride. The bactericide can be dissolved into water; in a paddy rice plantation area in summer, most ground is submerged by water, part of spray type bactericides and insoluble lipid bactericides cannot kill the pathogens of the roots; the provided bactericide can be dissolved in water and acts on the roots of paddyrice, and the diseases are better controlled.

Description

technical field

[0001] The invention relates to a fungicide, in particular to a summer rice fungicide and a preparation method thereof. Background technique

[0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Originally produced in China, rice was planted in the Yangtze River Basin of China seven thousand years ago. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice, which belong to direct economic crops. It is still the staple food of one-third of the human beings in the world. However, in the process of planting rice, because rice needs to be flooded for a long time, the roots are more prone to fungal infection and disease, resulting in reduced production and economic losses. At the same time, due to flooding, Ordinary fungicides are easily washed away by water, resulting in poor effect aft...
