Pesticide composition for preventing and controlling cotton field helicoverpa armigera and application thereof

Abstract

The invention discloses a pesticide composition for preventing and controlling cotton field helicoverpa armigera and application thereof. According to the pesticide composition for preventing and controlling the cotton field helicoverpa armigera and the application thereof, after the compounding of glyphosate and an organosilicone additive, quick action, control effect and persistence period of prevention and removal of helicoverpa armigera host plant Abutilon theophrasti Medic. by the glyphosate are accelerated, wherein after the compounding use of 300, 400 and 500 times of the glyphosate with 1000 times of the silicone additive, the control effect reaches 85% or more in 5 days and reaches 100% in 28 days after the use of the pesticide composition, and is much higher than the single-agentcontrol effect of the glyphosate; after the compounding of emamectin benzoate and the organosilicone additive, quick action, control effect and persistence period of prevention and control of the helicoverpa armigera are improved, and pest insecticide resistance is delayed, wherein the control effect is increased by 20% in 48 hours after the use of the pesticide composition; and a ternary compounding composition of the glyphosate, the emamectin benzoate and the organosilicone additive plays a dual effect of prevention and control of the helicoverpa armigera and simultaneously prevention and removal of the cotton field helicoverpa armigera host plant Abutilon theophrasti Medic., and plays an effect of two-preventing by one-spraying with a reduced pesticide using amount, thereby reducing labor cost.

Description

Technical field [0001] The invention relates to a pesticide composition for preventing and treating cotton bollworm and its application, belonging to the technical field of agriculture. Background technique [0002] Cotton (Gossypium hirstum L.) has an annual planting area of ​​5.33 million hectares in my country 2 Around 15% of the world’s planted area, it is an important economic crop and raw material for the textile industry in my country. However, cotton is also one of the crops where there are many kinds of pests and the pests are more serious, which causes cotton production to decrease by 15% to 20% throughout the year. The cotton bollworm (Helicoverpaarmigera) is the main pest of cotton. Since the 1990s, the cotton bollworm has occurred in my country year after year, and the annual economic loss is as high as tens of billions. In recent years, with the popularization and application of Bt cotton, the population of cotton bollworm can be effectively controlled, bringing si...
