Deltamethrin and badian oil insecticidal composition

Abstract

A stored-grain pest pesticide is characterized in that each component by the weight percentage is as follows: star anise oil 0.018-10.0, decamethrin 0.24-8.0, and the rest is carrier material. The inventive pest pesticide with the star anise oil and the decamethrin has obvious pest control effect on grain storage, and the pest control effect on the raw grain and seed storage of paddies, corns, beans, etc. is above 95%. The stored-grain pest pesticide has long lasting period without influence on the germination rate of the stored seeds. With the rich resources of raw materials, simple preparation technology, no waste pollution, convenient and safe usage, and low toxicity of products, the stored-grain pesticide residue meets the standard of WHO/FDA, which is further lower than the maximum residue limit in China.

Description

technical field [0001] The invention belongs to deltamethrin and star anise oil insecticide composition. Background technique [0002] So far, the losses caused by pests harming people's stored grains are very huge. Pests not only eat a lot of grains, but also have a great impact on the quality of grains, reduce the nutritional value of grains, and cause pollution to grains and the environment. With the development of modern science and technology, new technologies for the prevention and control of stored grain pests continue to emerge, such as sealing, air conditioning, low temperature control, sex attractants, etc. have been promoted to a certain extent. However, due to various reasons, the chemical fumigation control technology is widely used. Although this chemical fumigation method has a good control effect, it still has problems such as high cost, high labor intensity, unsafety, and high residual toxicity. This method has great limitations, and there are many differen...

Problems solved by technology

However, due to various reasons, the chemical fumigation control technology is widely used. Although this chemical fumigation method has a good control effect, it still has problems such as high cost, high labor intensity, unsafety, and high residual toxicity. This method has great limitations, and there are many differences in storage scale and grain storage conditions. It is urgent to produce a pest control agent that is effective under various conditions.

[0003] In the Chinese patent (Patent No. 89105548.7), a stored grain pest control agent based on Chinese herbal medicine and mixed with a small amount of fenvalerate is provided, which has a good control effect, but cyanogen The residual amount of pentethrin is relatively high, and it is necessary to continue to improve
