Description
Technical field
The invention belongs to technical field of pesticide, relate to the Pesticidal combination of a kind of fluorine-containing uride and organophosphorus compound.
Background technology
Fluorine uride (novaluron) chemical name: (±)-N-[[[3-chloro-4-[1,1,2-three fluoro-2-(trifluoromethoxy) ethyoxyls] phenyl] ammonia] carbonyl]-2,6-difluorobenzamide, molecular formula: C

4, the fluorine uride belongs to novel benzoyl area kind insect growth regulator, IGR, can organize the chitin in the stage of casting off a skin in the insect growth process synthetic, casts off a skin thereby influence to palm off as, makes insect can not form new epidermis when casting off a skin, and polypide is deformity and death.Can also regulate growing of insect, suppress molt metamorphosis, suppress the food speed of insect, have very high ovicidal activity.Mainly enter in the insect bodies, also can contact and enter in the insect bodies by insect's food-taking.Slowly kill off the insect pests by the destruction to the growth of expense adult, this process may continue about several days time, and is for the not effect of insect in adult stage, comparatively safe to beneficial insect to.
Organophosphorus insecticide is that China uses the insecticides the most extensive, that consumption is maximum, and it is various in style, and performance also varies, but comprehensively gets up to have following characteristics:
(1) insecticidal spectrum broad.
(2) most of kinds have and tag and stomach poison function, have systemic action or osmosis concurrently, main control on the ground, underground, bore dissimilar insects such as moth, pierce-suck type.Its insecticidal mechanism is the activity that suppresses the cholinesterase in the pest body, destroys neural normal conduction, causes a series of nervous system poisoning symptoms, up to death.
(3) toxicity is higher, should take care during use, and guarantee before the agricultural product results there is certain personal distance time, avoids residue of pesticide to poison.
(4) in environment, easily degraded is easily decomposed under alkali condition, therefore, can not use with alkaline matter.
(5) generally safer to crop, be difficult for producing poisoning.
Yet in the real process of agricultural production, the problem that pest control is easy to generate most is the generation of pest resistance to insecticide.The different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find fluorine uride and Profenofos, Hostathion, malathion can produce good synergistic effect after composite, and still unexposed about the composite relevant report in fluorine uride and Profenofos, Hostathion, malathion.
