Chinese chive maggot preventing and treating method

Abstract

The invention discloses a Chinese chive maggot preventing and treating method which comprises larva prevention and treatment and trapping and killing of adults. A preventing and treating liquid for larvae is prepared from the following components in parts by weight: 0.5-20 parts of gingko testa, 0.5-17 parts of capsicum, 0.5-10 parts of sulfur, 4-6 parts of sophocarpidine, 3-4 parts of bios, 6-12 parts of a mixed bacterial liquid mixed by white rot fungi, sulfonic fungi and pathogenic bacteria and 5-15 parts of alkaloid. An adult trapping and killing agent is prepared from the following components in parts by weight: 0.9-1.1 parts of white spirit, 9-11 parts of water, 3-4 parts of saccharose, 2-3 parts of glacial acetic acid and 0.09-0.11 part of deltamethrin. The method disclosed by the invention has a good trapping and killing effect; bio-source nutrients can repair Chinese chives which are damaged by chemical pesticides, the nutrients are promoted to be absorbed, and invasion of the Chinese chive maggots is better resisted; the liquid is non-toxic, easy to degrade, free of pollution and harmless to human body; the method is simple in process and low in cost, and the dosage of pesticides is reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for preventing and treating leek maggots. Background technique [0002] Leek is rich in vitamin C, carotene and rich trace elements, such as potassium, calcium, magnesium, selenium, iron, etc. Leek can warm the kidney and tonify deficiency, promote qi and blood circulation, dissipate stasis and detoxify, and harmonize the five internal organs. Leek is not only a commonly used vegetable, but also has medicinal value, such as lowering blood lipids, relieving constipation, preventing obesity, diabetes, cardiovascular disease, and cancer. Traditional Chinese medicine talks about the role of leeks in warming and nourishing the liver and kidneys, helping yang and strengthening essence, so it is called "Yangcao" in the Pharmacopoeia.

AI Technical Summary

Problems solved by technology

[0003] 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
