Embodiment 1

[0042] 1.1 Drugs to be tested

[0043] Neem is collected under the Neem tree that grows on the campus of Linyi University. After drying, use a pulverizer to pulverize the neem seeds, and put them in sealed bags for later use. 50% phoxim EC was purchased from Shandong Huayang Science and Technology Co., Ltd., and its main component was o, o-diethyl-o-phenylacetonitrile ketoxime) phosphorothioate.

[0044] 1.2 Determination of insect resistance index

[0045] Prepare several pots of the above-mentioned varieties of leeks in pots, with a diameter of 15 cm. 15 trees of each variety were cultivated in insect-proof nets.

[0046] Insert the end-3rd instar larvae of leek maggots into the surface soil layer close to the pseudostem of leek, 20 larvae per pot. Place it for 24 hours after being inoculated to allow it to drill into the underground part of the leek, and plant it under the same growth environment, water and fertilizer conditions, and set 3 repetitions.

Abstract

The invention belongs to the technical field of agricultural pest prevention and control, particularly relates to application of chinaberry seeds in prevention and control of bradysia odoriphaga larvae and further relates to a prevention and control method. The application of chinaberry seeds in prevention and treatment of bradysia odoriphaga larvae is the key protection content of the invention. The prevention and treatment method comprises the steps of S1, preparing a chinaberry seed medicament, specifically, drying chinaberry seeds collected from chinaberry seed trees in the sun, and crushing the chinaberry seeds to obtain chinaberry seed powder; S2, taking the chinaberry seed powder in the step S1, adding water according to the weight ratio of 1: (8-12), and soaking for 1-3 hours; and S3, after the Chinese chives are harvested, spraying the pesticide liquid in the step S2 to the roots of the Chinese chives in each hole, and covering a layer of thin fine soil after the pesticide liquid is sprayed. The method has the beneficial effects that the chinaberry seeds have a good effect on field control of the Chinese chive maggots, the control effect of 40g of chinaberry seeds is equivalent to that of phoxim, and the chinaberry seeds can be used as a substitute product for alternate mixing of chemical agents, so that green control of the Chinese chive maggots is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural pest control, and in particular relates to the application of neem seeds in the control of tardy-eyed fungus larvae of chives, and also relates to the above-mentioned control method. Background technique [0002] Leek is a perennial herb, which is favored by consumers because of its special flavor. Common diseases in leek production include gray mold of leek, blight of leek, root maggot of leek, etc. Among them, gray mold of leek and blight of leek are fungal diseases, which often occur in rainy summer. However, leek root maggot disease can occur all year round, and leek maggot is a stubborn underground pest, which brings devastating harm to the production of leek. Chive maggot is a common and difficult pest in leek production, which seriously restricts the production of leek. [0003] At present, the prominent problem in leek production is the excessive pesticide residues caused by the use...
