Method for preventing Chinese chive maggot biologically

Abstract

The invention relates to a method for preventing Chinese chive maggot. The method is characterized by comprising steps of smashing pepper and vitex (deciduous shrub of verbenaceae), mixing with water according to a proportion of 1:5:100, soaking for 24-72 hours, mixing soaked mixed supernate with biomass slurry according to a proportion of 1:1, after harvesting Chinese chives, irrigating the cut root of the Chinese chives by using the mixed liquor, so as to prevent Chinese chive maggot. The method solves the problems of excessive pesticide residue in the Chinese chives caused by root irrigation with chemical pesticide for preventing Chinese chive maggot, and is applicable to large-scale planting of organic or common Chinese chives.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for biological control of chive maggots. Background technique [0002] Chive maggot is a stubborn underground pest, which is a common pest in the production of leek. The larvae of leek maggot gather underground and eat the pseudobulb of leek. After the leek is damaged, it will affect the commodity value in the slightest, and cause the leaves on the ground to be thin and yellow, Wilting and rotting or even death in pieces has greatly harmed the interests of leek farmers. At present, most of the professional medicines used by leek farmers to control leek maggots are mainly phoxim (organophosphorus pesticide) and chlorpyrifos. Due to the characteristics of leeks, the safe interval of pesticides has not been reached when leeks are harvested, and the amount and frequency of use of such drugs by leek farmers cannot be effectively controlled. With the application of suc...

[0002] Chive maggot is a stubborn underground pest, which is a common pest in the production of leek. The larvae of leek maggot gather underground and eat the pseudobulb of leek. After the leek is damaged, it will affect the commodity value in the slightest, and cause the leaves on the ground to be thin and yellow, Wilting, rot, or even death in pieces, greatly endangering the interests of leek farmers

At present, most of the professional medicines used by leek farmers to control leek maggots are mainly phoxim (organophosphorus pesticide) and chlorpyrifos. characteristics, the safe interval of pesticides was not reached when leeks were harvested, and the amount and frequency of use of such chemicals by leek farmers could not be effectively controlled

With the application of such pesticides, the resistance of leek maggots to pesticides has become stronger and stronger, forcing leek farmers to use more toxic and more effective pesticides in violation of regulations, forming a vicious circle, resulting in excessive pesticide residues in leeks, and many "" "Poisoned leek" incident, serious cases even endanger life

Numerous agricultural practitioners are also aware of the seriousness of such incidents, are also interested in finding environmentally friendly methods, and have also developed some biological agents for the prevention and treatment of leek maggots, but due to higher costs and lower effects than chemical pesticides, etc. Get a wide range of effective promotion and application
