Description
The application is for dividing an application the applying date 2008.9.12 of original application, application number 200810211962.6 denominations of invention: based on the composition pesticide of Diacloden.
Technical field
The present invention relates to a kind of synergetic pesticide composition, particularly relate to a kind of synergetic pesticide composition that comprises Diacloden and be selected from arbitrary active insecticidal components of Avermectin, chlorfenapyr, Biphenthrin and dichlorvos.
Background technology
Diacloden (thiamethoxam) is the anabasine insecticide of a kind of efficient, low toxicity, wide spectrum, its mechanism of action mainly is that selectivity suppresses insect central nervous system nicotinic acid nAChR ligands, and then the normal conduction of blocking-up insect central nervous system, dead when causing insect the paralysis machine to occur.Diacloden not only have tag, stomach toxicity and systemic activity, and have better safety, wider insecticidal spectrum and the characteristics such as speed of action is fast, the lasting period is long, be to replace those high to mammalian toxicity, that organic phosphates, carbamates and the organochlorine insecticides of residual and environmental problem are arranged better kinds.Diacloden is to coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, can effectively prevent and treat the insect such as various aphids, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner and polytype produce resistance to chemical pesticide insect.Diacloden both can be used for cauline leaf, seed treatment, also can be used for soil treatment.Suitable crop is rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus etc.
