Abstract

The invention belongs to the technical field of pesticides, and particularly relates to a traditional Chinese medicine pesticide for preventing and controlling stored grain pests and a preparation method thereof. The traditional Chinese medicine pesticide for preventing and controlling the stored grain pests is prepared from, by weight, 8-15 parts of folium artemisiae argyi, 9-13 parts of flos caryophylli, 10-16 parts of storax, 7-12 parts of rue, 15-20 parts of pepper, 5-10 parts of rhizoma curcumae longae and 12-20 parts of garlic. The traditional Chinese medicine pesticide achieves joint usage of all the raw materials and is reasonable in formula, strong in smell, good in pesticidal effect, free of residues and pollution, capable of not generating the pesticide resistance and rapidly achieving the pesticide effects, stable in pesticide effect, capable of being stored for a long time and especially suitable for stored grain pest prevention and control.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a traditional Chinese medicine pesticide for preventing and controlling stored grain pests and a preparation method thereof. Background technique [0002] In the process of grain storage, the harm of stored grain pests is the most important factor affecting food security. The method currently used to effectively prevent stored grain pests is chemical fumigation. This method has a good control effect, but it has high cost and high residual toxicity. , environmental pollution and unsafe issues. Therefore, choosing to develop natural bioactive substances, such as substances produced by plants, insects and microorganisms, and developing biorational pesticides that are highly effective against pests, safe for the environment and non-target organisms have become the needs of modern pesticide development. Since traditional Chinese medicine pesticides are derived from natu...
