Embodiment 1
[0030] Mix 3g of diallyl disulfide, 1g of diallyl trisulfide, 1g of valeric acid, and 10g of trichlorfon, add 20g of acetic acid, 5g of Tween-805g, and 60g of ethanol respectively, stir and fully dissolve to obtain 100g of uniform and transparent Liquid preparation, diluted with water at a ratio of 1:100, put 20 ml of the diluted solution in a plastic small pot in the leek greenhouse, place a pot every 4 square meters, add 20 ml of the diluted solution every week, and measure the leek after 60 days The harm rate of maggots is only 2.8%.
Embodiment 2
[0032] Mix 0.1 g of valeric acid, 0.01 g of heptadecane, 0.1 g of tetramethylpyrazine, and 1 g of deltamethrin, and add 50 g of acetic acid, 10 g of Span-4010 g, 20 g of ethylene glycol, 50 g of sucrose, and 869 g of water respectively as additives. Stir and fully dissolve to obtain 1000g of a uniform and transparent liquid preparation. Put 20ml of this liquid in a small plastic pot in the leek greenhouse, place a pot every 4 square meters, add 20ml of diluent every week, and measure the leek maggot after 60 days The hazard rate is only 3.6%.
Embodiment 3
[0034] Mix 0.1g of diallyl disulfide, 0.01g of diallyl tetrasulfide, 0.1g of tetramethylpyrazine, 2g of phenylethyl alcohol, and 5g of dimethoate, and add 10g of ethyl acetate, Tween-803g, 80g of acetone, stirred and fully dissolved to obtain 100g of a uniform and transparent liquid preparation, diluted with water at a ratio of 1:100, and 20ml of the diluted solution was placed in a leek greenhouse in a plastic small pot, one pot per 4 square meters, replenished every week Add 20 milliliters of diluents, and after 60 days, it is measured that the harm rate of leek maggots is only 3.3%.

Abstract
The invention provides a bradtsua idiruogaga trapping and killing agent, a preparation method and an application thereof. The trapping and killing agent includes a trapping agent and a killing agent. The bradtsua idiruogaga trapping and killing agent is simple in preparation method, employs easy-to-obtain raw materials, has stable performance and is convenient to use. Compared with chemical prevention and treatment on the bradtsua idiruogaga in the prior art, the trapping and killing agent, through addition of trace amount of the trapping agent, can effectively control damage from the bradtsua idiruogaga and reduces use time and amount of pesticide, thereby effectively solving the problems of resistance, pesticide residue and environment pollution due to chemical prevention and treatment. The trapping and killing agent can trap and kill adult worms of the bradtsua idiruogaga high-effectively, has a long lasting time, can directly kill the adult worms or deprive normal oviposition capability of the adult worms, thereby greatly reduces the population number of the bradtsua idiruogaga. The trapping and killing agent provides reliable substance guarantee for green prevention and control on leek.
Description
technical field [0001] The invention belongs to the field of green prevention and control of harmful organisms, and in particular relates to a leek maggot trap and its preparation method and application. Background technique [0002] Chives belong to the Liliaceae Allium genus and are perennial root plants. Leek is a vegetable that people like to eat. Because of its cold resistance, heat resistance and strong adaptability, it has become one of the most widely produced fragrant leafy vegetables. Chive maggot is the most serious pest in leek production, and it is already the main factor restricting the production of leek. It is a general term for chive mosquitoes and fly larvae, mainly including leek maggots and onion flies. Chive maggots mainly harm leek leaf sheaths. , young buds and bulbs, causing bulbs to rot and leaves to die. In mild cases, the plants will be yellow and lodging. Because it occurs every year, the species vary greatly in different regions and seasons, an...
