Abstract
The invention relates to an insecticidal composition, which comprises two active ingredients, i.e. dinotefuran and butene-fipronil. The insecticidal composition is low in toxin and efficient, is mainly used for preventing and controlling the rice brown planthopper, has an excellent insecticidal activity, and is safe and nontoxic to plants, the insecticidal spectrum is enlarged, the drug resistance is delayed while the use amount is reduced, the lasting period is prolonged, and the pollution on the environment is reduced.
Description
technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition of dinotefuran and butene fipronil. Background technique [0002] Dinotefuran is a third-generation neonicotinoid insecticide developed by Mitsui Chemicals. Its chemical structure is very different from that of the existing neonicotinoid insecticides. Its tetrahydrofuryl group replaces the previous chloropyridyl and chlorothiazolyl groups, and it does not contain halogen elements. At the same time, it is also different from nicotine in terms of performance. The agent has a wide insecticidal spectrum, excellent systemic penetration, and shows high insecticidal activity at a very low dose. The agent is very safe to mammals, birds and aquatic organisms, and has no harm to crops. It can be used for many crops such as rice, fruit trees and vegetables. It was introduced in Japan in 1993, and has since been registered in Asian countries represented by South Korea...
