A leek maggoticide

Abstract

The invention relates to a leek maggot killing agent. The leek maggot killing agent comprise the following effective components in percentage by weight: 6-8 parts of sulphur, 1-2 parts of a high-efficiency dispersing agent, and 1-2 parts of a synergist. The leek maggot killing agent is prepared by taking the sulphur as a base component, adding the high-efficiency dispersing agent and the synergist and mixing, and crushing into 1800-2600-mesh superfine powder by using an airflow crushing device. The leek maggot killing agent is simple in production process and stable in product quality; after the superfine powder is mixed with water, the dispersibility is excellent and the suspensibility is high and a uniform and stable suspension is formed in water rapidly; the suspension permeates into the ground surface to contact a leek maggot body and corrode the leek maggot body so as to solidify proteins and block pores of the leek maggot body, a leek maggot is further killed; the leek maggot killing agent is lasting in effect, low in cost, safe, non-toxic, pollution-free and residue-free, not only reduces the burden of a leek farmer, but also has an important significance for environment protection and food safety.

Description

technical field [0001] The invention relates to an insecticide suitable for killing leek maggots, in particular to a leek maggoticide, which belongs to the technical field of pesticides. Background technique [0002] Leek maggots are devastating pests that harm the growth of chives. The leek maggot larvae gather on the bulbs and tender stems of the underground part of leek, and eat the bulbs and buds. The newly hatched larvae first damage the base of the leek leaf sheath and the upper end of the bulb. In spring and autumn, they mainly damage the young stems of leek and cause rot. The leek leaves turn yellow and die. In summer, the larvae move downward and bore into the bulb. In severe cases, the bulb rots and the whole leek dies. Statistics show that the probability of leek being infected by leek maggots after two years of growth is as high as about 80%, especially with the increase of off-season leek and leek production, the probability of leeks being infected by leek magg...
