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

4, fluorine uride belongs to novel benzoyl area kind insect growth regulator, IGR, can organize the chitin synthesis in the stage of casting off a skin in insect growth process, thus impact palm off as and cast off a skin, make insect can not form new epidermis when casting off a skin, polypide is deformity and dead.Can also regulate growing of insect, suppress molt metamorphosis, suppress the food speed of insect, there is very high ovicidal activity.Mainly by insect's food-taking, enter in insect bodies, also can contact and enter in insect bodies.By the destruction of expense adult growth is slowly killed off the insect pests, this process may continue about several days time, for the not effect of insect in adult stage, comparatively safe to beneficial insect to.
Organophosphorus insecticide is that China is used the most extensively, the maximum insecticides of consumption, and it is various in style, and performance also varies, but comprehensively gets up to have following features:
(1) insecticidal spectrum is wider.
(2) most of kinds have and tag and stomach poison function, have systemic action or osmosis concurrently, main control on the ground, underground, bore the dissimilar insects such as moth, pierce-suck type.Its insecticidal mechanism is the activity that suppresses the cholinesterase in pest body, destroys neural normal conduction, causes a series of nervous system poisoning symptoms, until dead.
(3) toxicity is higher, should take care, and guarantee there is certain personal distance time before agricultural product results during use, avoids residue of pesticide poisoning.
(4), in environment, easily degraded is easily decomposed under alkali condition, therefore, and can not be mixed 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 the most easily produces is the generation of pest resistance to insecticide.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 is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor research, find after fluorine uride and Profenofos, Hostathion, malathion is composite to produce good synergistic effect, and not yet open about the composite relevant report in fluorine uride and Profenofos, Hostathion, malathion.
