Trapping sweet and sour liquid for eradicating delia floralis fallen

Abstract

The invention discloses a trapping sweet and sour liquid for eradicating delia floralis fallen. The liquid comprises the following components by weight: 2-4 parts of vinegar, 8-10 parts of water, 1-3 parts of sugar, 2-4 parts of trichlorfon powder, 1-3 parts of root of Scutellaria baicalensis, 1-3 parts of clove and 1-2 parts of ginger. The liquid has simple proportion, and the liquid flows from the core of the cabbage to rhizosphere to ensure the moist soil around the roots; and usually 1-2 times of root irrigation can kill delia floralis fallen. the drug is convenient for usage and can effectively kill delia floralis fallen. When cabbage the field has delia floralis fallen infestation, 90% trichlorfon, 40% dimethoate emulsifiable concentrate and vinegar are mixed with extracts of Scutellaria baicalensis, cloves and ginger; and the mixture is used for root-irrigation. The liquid has simple ratio; in early August, big pits in the size of a bowl are dug in the field every 8-10 m; and a plastic bag is put into each pit according to the size, 100g of the mixed liquid is poured, and the mixed liquid is added about every 10 days. In this way, a large number of imagoes can be killed.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a sweet and sour liquid for trapping and killing radish flies. Background technique [0002] During the growth of autumn cabbage, ground maggots (also known as root maggots) are the most taboo. They bite the epidermis of Chinese cabbage roots, causing germs in the soil to take advantage of the gap, causing Chinese cabbage to fall and rot, which not only reduces the yield of cabbage, but also affects the growth of cabbage. Edible value of cabbage. If it is not prevented and controlled in time, the whole field can be damaged and serious losses can be caused to vegetable farmers. The ground maggots that harm autumn cabbage are the larvae of radish flies, which are oligophagous pests and mainly damage cruciferous vegetables such as cabbage and radish. [0003] There is one generation of radish flies every year in various places, and they survive the winter in the soil as...

Problems solved by technology

Commonly used chemical pesticides, because of years of spraying, have caused ground maggots to develop drug resistance, and the killing effect is not good. In view of this technical problem, it is necessary to have a simple proportion to make the liquid flow from the cabbage heart to the rhizosphere to ensure The root soil is moist, and the roots are generally irrigated 1 to 2 times to kill ground maggots
