Insect-resistant pesticide for vegetables and preparation method of insect-resistant pesticide

Abstract

The invention discloses an insect-resistant pesticide for vegetables. The insect-resistant pesticide is prepared by taking a folium artemisiae argyi extracting solution, an iris japonica thumb extracting solution, a melia azedarach extracting solution, an euphorbia helioscopia extracting solution, a duranta repens extracting solution, a sweet wormwood extracting solution, white vinegar and pepper spray as raw materials. The insect-resistant pesticide can effectively prevent and kill vegetable worms such as aphids and snails, and enable the vegetables to grow luxuriantly, so as to improve the yield of the vegetables. Meanwhile, the liquid drug residual period of the insect-resistant pesticide is only 8-12 days, thus being non-toxic and harmless to people and livestock. The invention also provides a preparation method of the insect-resistant pesticide. The insect-resistant pesticide disclosed by the invention is remarkable in effect, low in cost, and green and pollution-free, thus having a broad market application prospect.

Problems solved by technology

However, vegetables are extremely vulnerable to insect damage during the growth process, mainly including aphids, snails and other vegetable insects. If vegetable insects are not prevented and killed in time, the yield and quality of vegetables will be seriously affected.

[0003] At present, when people control vegetable insects, they generally use high-concentration pesticide spraying to kill them. Although the control effect is very good, the residual pesticide components in vegetables are too high, which will cause harm to the human body and make people susceptible to various diseases. Various diseases can easily lead to a decline in the immunity of various functions of the human body. Long-term consumption of vegetables with high pesticide residues is more likely to cause various diseases.
