Description
Technical field
The present invention relates to a kind of composition pesticide, particularly relate to a kind of composition pesticide containing cycloxaprid and amide-type insecticide, and the application of described composition in control Lepidoptera, Semiptera, coleoptera, thrips, Hymenoptera, Diptera pest and mite pest.
Background technology
The use of agricultural chemicals has very long history, has played huge effect in the process of mankind's nature remodeling.Facilitate the great development of agricultural.Huge economic benefit is brought to the mankind.China kills insect in the first seven century to Christian era in Christian era in the first five century with thick grass, clam charcoal ash, male to bring up etc.Before the forties in 20th century, based on the natural and inorganic drug epoch of natural drug and inorganic compound agricultural chemicals; From early in the twentieth century, enter the epoch of synthetic organic pesticide.The development situation of current agricultural chemicals: developed country has entered Cultivar replacing from the seventies in last century and regenerated, China's agricultural chemicals has had large development from the eighties in last century, but great majority are set up from imitated basis and grown up, until the nineties, China's pesticide species just started to upgrade.But agricultural chemicals is still based on old kind, and high poison, persistent pesticide are taken as the leading factor, and pesticide species ratio reasonability is poor, operation technique low SI, and consumption is large, and environmental pollution is serious.Enter 21 century, agricultural chemicals is low to toxicity, active high, the good future development of Environmental compatibility gradually.
Chinese patent CN101747320A, CN102093389A individually disclose a kind of cycloxaprid insecticides, cycloxaprid (chemical name: 9-((6-chloropyridine-3-base) methyl)-4-nitro-8-oxa--10,11-glyoxalidine also [2,3-a] dicyclo [3,2,1] pungent-3-alkene) molecular structure as shown in structural formula (I).
Cycloxaprid mechanism of action is novel, research shows: when cycloxaprid consumption is lower than 10 μMs, nAChR is not shown to the reaction of activator, and show as pure agonist character, completely different from the mechanism of action of the anabasine receptor stimulating agent of current commercial neonicotinoid insecticide kind, obtain and use comparatively widely.On this basis, Chinese patent CN102197804A, CN102197807A, CN102197808A individually discloses the formulation such as suspending agent, wetting powder, water dispersible granules of cycloxaprid insecticide.
But relevant cycloxaprid insecticide high cost in prior art, be unfavorable for widely using of cycloxaprid insecticide, and, the use single insecticide of long-rang dependence, easily develop immunity to drugs, therefore, need a kind ofly can to have good control efficiency, simultaneously can also avoid the insecticide that resistance, quick-acting are good, the lasting period is long insect.
