Insecticide special for cabbage caterpillars

Abstract

The invention relates to the technical field of insecticides for plants, in particular to an insecticide special for cabbage caterpillars .The insecticide is prepared from, by weight, 8-10 parts of mebendazole, 2-5 parts of palmitic acid, 15-18 parts of calcium hydrophosphate, 15-20 parts of citric acid, 20-30 parts of ethyl alcohol and 500-600 parts of water .The insecticide is free of toxic properties, a traditional injurious insect killing mode is changed for insect prevention, injurious insects can be reused after falling from leaves, the income of farmer households is increased, and the insecticide is quite suitable for green organic plantation.

Description

technical field [0001] The invention relates to the technical field of insecticides for plants, in particular to a special insecticide for cabbage caterpillar. Background technique [0002] Cabbage cabbage butterfly is common in various places, and the annual algebra is different in different places. All places overwinter as pupae and reach the peak eclosion stage in May. The eclosion adults feed on nectar, mate and lay eggs, and the newly hatched larvae eat egg shells first, and then feed on leaves. Then switch to eating leaves of cruciferous plants. The body is green, so people call it cabbage caterpillar. The larvae of cabbage caterpillar bite the leaves of the host. Before the 2nd age, they only eat the mesophyll, leaving a layer of transparent skin. After the 3rd age, they eat Leaf holes or notches, when serious, all leaves are eaten up, leaving only thick veins and petioles, resulting in extinction, easy to cause the prevalence of cabbage soft rot, serious overlappin...

Problems solved by technology

Then switch to eating leaves of cruciferous plants. The body is green, so people call it cabbage caterpillar. The larvae of cabbage caterpillar bite the leaves of the host. Before the 2nd age, they only eat the mesophyll, leaving a layer of transparent skin. After the 3rd age, they eat Leaf holes or notches, when serious, all leaves are eaten up, leaving only thick veins and petioles, resulting in extinction, easy to cause the prevalence of cabbage soft rot, serious overlapping of generations of cabbage caterpillars, large number of eggs, rapid emergence of drug resistance, At present, most of the control methods are based on killing with chemical agents, the price is high, and the properties of the medicine are insufficient, which has a great impact on the quality of vegetables.
