Abstract

The invention relates to a disinsection sprinkling oil concentrate, which mainly composed of components with the following mass content: 40 to 65 percent of liquid paraffin, 2 to 5 percent of jinggangmycin, 1 to 3 percent of avermectin, 2 to 10 percent of tea saponin, 0.5 to 2 percent of water soluble extractive of plocamium telfairiae harv, 0.5 to 6 percent of water soluble extractive of tobacco leaves, 1.5 to 3 percent of emulsifier and the balancing amount of water; the emulsifier is mixture of sapn and tween with the mass ratio of 3: 1. The disinsection sprinkling oil concentrate of the invention has broad spectrum bacteriostasis and sterilization effect, quick action and long action are combined together, an efficacy period of 35 days can be maintained, no toxicity can be left on human and livestock, the environment can not be polluted, the effective drug consumption can be reduced, the generation of drug fastness can be suspended, and thereby the disinsection sprinkling oil concentrate can be used for the disinsection and the prophylaxis to fruits, vegetables, garden flowers, lawns, and urban gardens and trees.

Description

(1) Technical field [0001] The invention relates to a safe and environment-friendly insecticidal spray emulsifiable concentrate and a preparation method thereof. (2) Background technology [0002] At present, the vast majority of pesticides are chemical pesticides, which have high or even extremely high toxicity. The pesticide residues during the spraying process and later have serious adverse effects on the environment and human beings; at the same time, chemical pesticides make pests develop obvious resistance to pesticides. , leading to continuous increase in the dosage of pesticides, and the control effect is getting worse and worse. Therefore, there is an urgent need for a broad-spectrum insecticidal effect, safe and environmentally friendly insecticides to replace highly toxic chemical pesticides. (3) Contents of the invention [0003] The object of the present invention is to provide a kind of insecticidal spray emulsifiable concentrate with broad-spectrum insectic...
