Abstract

The invention discloses an insect-preventing insecticide for vegetables and a preparation method thereof. The insect-preventing insecticide is prepared by 1.5-3.0kg of Euphorbia helioscopia, 0.5-1.2kgof Laggera pterodonta, 0.1-0.8kg of Artemisia vulgaris, 0.01-0.5kg of white vinegar and 6-18kg of water. The insect-preventing insecticide can effectively prevent and repel and kill vegetable insectssuch as cabbage worms, cornbug and aphids and can increase vegetable yield, the residence time of the insect-preventing insecticide liquid is shortened to 6-8 days, and the insect-preventing insecticide is harmless to human and livestock. The preparation method has the advantages that effective components in the raw material components are sufficiently extracted, and high raw material utilizationrate is achieved. The insect-preventing insecticide has an evident repelling and killing effect on the vegetable insects and is simple in formula, efficient, low in toxicity, free of residues and pollution, green and promising in market application prospect.
