Compound agent for preventing and treating diseases and pests of cotton in seedling stage

Abstract

The invention relates to agricultural chemistry, in particular to a polypharmaceutical for preventing and controlling plant diseases and insect pests of the seedling stage of cotton. The polypharmaceutical is characterized in that the polypharmaceutical consists of active constituents such as hymexazol, ruisheng, humic acid, a synergistic agent, an adhesive and so on, and a supporting auxiliary agent system, and is a suspended liquid which has a pesticide-fertilizer compounding type and is produced by processing technologies such as wet crushing, ultrafine grinding and so on. Concrete components in percentage by weight are 30 percent of ruisheng, 40 percent of bochemistry favic aid, 20 percent of hymexazol, 1.2 percent of novel strong permeability cinnamyl ketone or laurocapam, and 8 percent of cotton seed oil or soybean oil. Through control experiments to the plant diseases and insect pests of the seedling stage of the cotton, the control effect of the product is 95 percent or so, and the product has the effect of increasing more than 26 percent of yield, has pesticide effect, and also has fertilizer effect.

Description

technical field [0001] The invention relates to agricultural chemistry, in particular to a compound medicament for preventing and controlling cotton seedling pests. Background technique [0002] Due to the influence of geological conditions and planting habits, the phenomenon of continuous cropping of cotton in my country is relatively serious. The phenomenon of continuous cropping for 4-6 years is very common, and some plots even last for about 10 years. Moreover, in recent years, there are many cloudy days and low temperatures after cotton sowing , seriously affecting the normal growth and development of cotton, resulting in serious cotton seedling pests and diseases, and the death of cotton seedlings. The mortality rate of cotton seedlings is about 1.20%, more than 4% in heavier years, and 12.40% in heavier plots, even with or without emergence. The pests and diseases that harm cotton seedlings are mainly cotton seedling blight, and often mixed with cotton seedling anthra...
