Abstract

A biological control method for bradysia odoriphaga is characterized by using 6-10% of fresh euphorbia lunulata and 90-94% of water and comprising soaking euphorbia lunulata in water for 24-72 h according to the ratio, and after seedlings are harvested, pouring the soaking liquid to stubbles or roots of leeks. The problem of pesticide residue due to bradysia odoriphaga control through a chemical method is solved. The method is suitable for non-toxic pollution-free production of leeks.

Description

technical field [0001] The present invention relates to the field of prevention and control of vegetable diseases and insect pests, specifically a method for controlling leek root maggots utilizing cat's eye grass (synonym: cat's eye, hitting bowl flower, hitting bowl tree, hitting pot and hitting bowl). Background technique [0002] At present, in the prevention and control of leek maggots, chemical control methods such as spreading or watering pesticides on the roots are mainly used. The disadvantage is that leeks absorb certain pesticides and remain in the body, which seriously endangers human health after eating. Contents of the invention [0003] The present invention solves the problem of using pesticides to prevent and treat leek maggots, leeks contain residual pesticides, and endanger human health after eating, and invents a method of using cat's eye grass (synonyms: cat's eye, hitting a bowl of flowers, hitting a bowl, hitting a pot and hitting a bowl) The method ...
