Problems solved by technology

[0003] At present, the methods for controlling the larvae of T. chives are mainly chemical pesticides such as abamectin and organophosphorus, but there are the following defects: ①The larvae of T. larvae live in the underground soil, and it is difficult to kill them with general pesticides; ② Use methamidophos, monocrotophos and other high-residue and highly toxic organophosphorus pesticides mixed with water to kill leek maggots, because a large amount of organophosphorus pesticides will be absorbed by the roots of leeks and remain in the leeks, so it is not easy to be easily washed off. poisoning after ingestion
[0004] There are also some botanical pesticides on the market. The main mechanism of action is mostly the use of some toxic traditional Chinese medicines for deployment. Although they are plant sources, they are still inseparable from serious poisons. There are hidden dangers in production and sales, and they also affect the natural growth of leeks. , resulting in a decline in the nutritional value and taste of leeks

Description

Technical field [0001] The present invention involves the field of biological insecticidal, and specifically involves a composition and preparation method for preventing and controlling leeks. Background technique [0002] Leek is a perennial herbaceous plant, and is a vegetable that the general public and the people like very much.The Bradysia Odoriphaga yang et zhan mainly endangers lily vegetables such as leek, green onions, onions, shallots, garlic, and occasionally endangered lettuce, vegetables, celery, etc., which is one of the main pests of green onion and garlic vegetables.The hazard form of larvae: Spring and autumn seasons mainly cause the young stems of leeks to rot, causing the leek leaves to die.In summer, larvae moved down into the bulbs. [0003] At present, the method of preventing and controlling leeks is mainly chemical pesticides such as Avin, organic phosphorus, etc., but there are the following defects: ① Leek delayed eye mosquito larvae live in underground ...
