Description

technical field [0001] The invention belongs to the technical field of crop planting, in particular to a grain insect repellent. Background technique [0002] At present, chemical insect repellants are still widely used in agricultural production and crop control. In general, large-scale grain storage mostly uses toxic and harmful insecticides such as aluminum phosphide and dichlorvos. Due to the high toxicity and high residue of chemical components, It is easy to produce drug resistance, and cause environmental pollution, which constitutes a negative impact on the virtuous cycle of ecology, which is very unfavorable in terms of green, environmental protection, and ecology. In order to solve this problem, a non-toxic and harmless grain insect repellent was invented. Contents of the invention [0003] The invention proposes a grain insect repellent, which solves the defects of the insect repellent in the prior art. [0004] Technical scheme of the present invention is rea...
