Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains fluorine pyridine worm amine nitrile and biogenic class.
Background technology
Fluorine pyridine worm amine nitrile, English common name (sulfoxaflor), structural formula: C
10H
10F
3N
3OS chemical name: [1-[6-(trifluoromethyl) pyridin-3-yl] ethyl] methyl (oxygen)-λ 4-sulfydryl cyanamide.Fluorine pyridine worm amine nitrile is an insecticide of sulfimide, and sulfimide acts on the nervous system of insect, promptly acts on binding site unique in the choline receptor and brings into play insecticidal function.Can be through leaf, stem, root absorption and get in the plant corpus.
AVM, English common name (abamectin), molecular formula: C
48H

70O
14(B1b), AVM is tagged, stomach toxicity, penetration be strong.It is a kind of macrolide disaccharide compounds, is the natural products that from edaphon, separates, and insect and mite class is had tag with stomach poison function and faint fumigation action is arranged, no systemic action.But it has very strong osmosis to blade, can kill subepidermal insect, and the longevity of residure is long.It does not kill ovum.What its mechanism of action was different with general insecticide is that it disturbs neurophysiology movable; Stimulate and discharge the r-reanal; And the r-reanal has inhibitory action to arthropodan nerve conduction; The mite class becomes, if mite and insect and larva with paralysis symptom promptly appears after medicament contacts, inertia is not got food, death after 2-4 days.Because of not causing that insect dewaters rapidly, so its lethal effect is slower.But though predatism and parasite are had direct killing effect, because of plant surface is residual few, therefore little to the damage of beneficial insect.Obvious to the root nematode effect.
Multiple killing teichomycin (Spinosad) has insect and to tag fast and stomach poison function, and blade is had stronger osmosis, can kill subepidermal insect, and the longevity of residure is longer, and some insects are had certain ovicidal action.No systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some measures the pest species of eating blade greatly in coleoptera and the orthoptera, relatively poor to the control efficiency of sucking pest and mite class.Safer to the predator insect, unique because of insecticidal action mechanism, do not find as yet at present to have mutual drug-fast report with other insecticides.Plant safety there is not poisoning.Be suitable for using on vegetables, fruit tree, gardening, the crops.Insecticidal effect receive to rain influence less.
Emamectin-benzoate (emamectin benzoate); Chemical name: 4 '-Biao-methylamino-4 '-the deoxidation abamectin benzoate; These article are efficient, wide spectrum, the longevity of residure are long; Be good insecticidal/acaricidal agent, its mechanism of action hinders pest movements nerve information transmission and makes the health paralysis dead.The mode of action is main action of contace poison with stomach toxicity, and crop is not had interior absorption ability, but effective infiltration of institute used crop epidermal tissue, thereby has the longer longevity of residure.To control cotton bollworm, Lepidoptera; Mite class, coleoptera and homoptera pest have high activity; And do not produce and intersect with other crops, soil with in be prone to the noresidue of degrading, free from environmental pollution; In the routine dose scope to useful insect and natural enemy, people, animal safety, can with most of combined use of pesticides.
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's research; Discovery can produce good synergistic effect with fluorine pyridine worm amine nitrile and AVM, multiple killing teichomycin, emamectin-benzoate after composite, and still unexposed about the composite relevant report of fluorine pyridine worm amine nitrile and AVM, multiple killing teichomycin, emamectin-benzoate.
