Compound drug for killing root maggot in root irrigation manner

Abstract

The invention discloses a compound drug for killing a root maggot in a root irrigation manner. The compound drug comprises the following ingredients in parts by weight: 2-4 parts of 50% phoxim missible oil, 8-10 parts of 40% dimethoate missible oil, 1-3 parts of 90% dipterex liquid, 2-4 parts of ammonia water, 1-3 parts of garlic, 1-3 parts of clove, and 1-2 parts of pericarpium citri reticulatae. The compound drug is simple in composition; the drug liquid can flow around the rhizosphere from cabbage core, so that the root part soil can be kept moist; generally, the root irrigation manner can be performed once or twice to kill the root maggot. The compound drug is convenient to use and can effectively kill the root maggot. When the root maggot damages the garbage in the field, the 90% dipterex, the 40% dimethoate missible oil and the 50% phoxim missible oil can be mixed with the leach liquor of the garlic, the glove and the pericarpium citri reticulatae to irrigate the root; about 200 g of the irrigation liquid can be used for each cabbage; the drug liquid flows from the cabbage core to the rhizosphere; the root part soil is kept moist; generally, the root irrigation manner can be performed once or twice to kill the root maggot.

Description

[0001] Technical field: [0002] The invention relates to the technical field of vegetable planting, in particular to a compound medicine for eradicating ground maggots by root irrigation. [0003] Background technique: [0004] 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. [0005] There is one generation of radish flies every year in various places, and they surv...

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
