Abstract

The invention relates to a hygienic insecticide compound containing pirimiphos methyl and pyrethroid. Compared with a single agent, the compound has an obvious synergistic effect, can promote the insecticidal effect, can achieve a synergic coefficient above 130 and especially has excellent knock-down and killing effects to hygienic insects having pyrethroid resistance. Besides, after pirimiphos methyl with low toxicity, low stimulation and low use frequency is selected as a lethal agent of the hygienic insecticide compound and is compounded with ultrahigh knock-down efficient low-toxicity and low-stimulation pyrethroid chlorofluorothrin, d-trans-chloropropyrethrin, transfluthrin, sevoflurane methothrin or tetramethylfluthrin, the knock-down and lethality properties of the active ingredient to the target are both greatly promoted and the cost performance ratio is ultrahigh; furthermore, the compound is prepared into a micro-capsule suspension agent which has excellent physical and chemical properties and slow release effect, so that the target killing effect is greatly promoted; the preparation is low-toxicity and stimulation-free and is suitable for indoor and outdoor hygienic insect prevention and control.

Description

technical field [0001] The invention relates to the field of hygienic insecticides, in particular to a hygienic insecticide composition containing pirimiphos-methyl and its application. Background technique [0002] Pirimiphos-methyl, chemical name: O-(2-diethylamino-6-methyl-4-pyrimidinyl) O, O-dimethyl phosphorothioate, which was developed by ICI in 1974 Broad-spectrum, quick-acting organophosphorus insecticide and acaricide, with contact and fumigation effects, good insecticidal effect and long-lasting efficacy. acute oral LD 50 2050mg / kg, 1180mg / kg for male mice, 1150-2300mg / kg for male rabbits, 1000-2000mg / kg for female guinea pigs; acute percutaneous LD in rabbits 50 >2000mg / kg. It is non-irritating to the skin and eyes, and is recommended by WHO for the prevention and control of sanitary pests. The agent has a strong lethal effect and has a certain quick-killing performance. This technical research shows that pirimiphos-methyl and a small amount of specific pyr...
