Problems solved by technology

[0002] Plutella xylostella is the most widely distributed pest in the world. The first instar larvae only eat the mesophyll, leaving the epidermis, forming transparent spots on the vegetable leaves, "opening the skylight", and the 3rd to 4th instar larvae can eat the vegetable leaves into holes And nicks, when severe, the whole leaf is eaten into a net shape, and the central leaf is often concentrated in the seedling stage, affecting the center of the heart, and on the seedling plant, it is harmful to the tender stem, young pods and grains. The generation overlap of diamondback moth is serious, and the number of eggs Large, rapid resistance to pesticides, the current control methods are mostly based on chemical agents, the price is high, and the drug resistance is insufficient, which has a great impact on the quality of vegetables

Abstract

The invention relates to the technical field of insecticide for plants, particularly to an insecticide special for plutella xylostella. The insecticide is prepared from the following raw materials in parts by weight: 6 to 8 parts of mebendazole, 2 to 5 parts of palmitic acid, 12 to 15 parts of calcium hydrogen phosphate, 15 to 18 parts of citric acid, 20 to 25 parts of ethyl alcohol and 500 to 600 parts of water. The insecticide special for the plutella xylostella is nontoxic; the conventional pest killing method is replaced by pest prevention; the pests can be reused after falling from leaf surfaces, so that the benefit of a farmer is increased, and the insecticide is extremely suitable for green organic planting.
