Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of composition pesticide that contains ethyl pleocidin.
Background technology
Ethyl pleocidin, English common name (spinetoram), structural formula: C

69NO
10Ethyl pleocidin is made up of ethyl pleocidin-J and two kinds of components of ethyl pleocidin-L, acts on the nervous system of insect, and diamond-back moth, beet armyworm, Liriomyza, thrips, prodenia litura, lima bean pod borer are had good control efficiency.
AVM, English common name (abamectin), molecular formula: C

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.
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 ethyl pleocidin and AVM, emamectin-benzoate after composite, and still unexposed about the composite relevant report of ethyl pleocidin and AVM, emamectin-benzoate.

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent of ethyl pleocidin effective active composition B is diluted to five series concentration during test, places beaker subsequent use respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament is soaked taking-up behind the 5s, dries naturally in the soup that configures, put into insect box; Connect then and supply examination 3 instar larvaes, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 20, establishes blank simultaneously, checks dead borer population in 72h; Calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is regarded as invalid test greater than 10%.Computing formula is following:
To supply examination insect corrected mortality to be converted into probit value (y), concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with the ethyl pleocidin is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of theoretical toxicity index (TTI)=ethyl pleocidin of M
Ethyl pleocidinTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
