Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains spiral shell worm ethyl ester.
Background technology
Spiral shell worm ethyl ester (spirotetramat) chemical name: 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2,5-xylyl)-1-azaspiro [4,5]-last of the ten Heavenly stems-3-alkene-2-ketone, molecular formula: C

3, MTI-446 third generation nicotinic insecticide.The chemical constitution of itself and existing nicotinic insecticide is far from each other, and chloro-pyridine base, chloro thiazolyl before its tetrahydrofuran base has replaced do not contain the halogen family element.Simultaneously, also different with nicotine at aspect of performance, so, people are referred to as " furans nicotine " at present, have tag, strong, the quick-acting height of absorption in stomach toxicity and the root, characteristics such as the lasting period is long, insecticidal spectrum is wide, and sucking insect there is excellent preventive effect, and has namely shown very high insecticidal activity at very low dosage.Be mainly used in preventing and treating aphid, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof on the various crop such as wheat, paddy rice, cotton, vegetables, fruit tree, tobacco leaf, simultaneously coleoptera, diptera and Lepidoptera, diptera, beetle order and total wing order insect are had efficiently, and to blattaria, have efficiently from sanitary insect pests such as ant, houseflies.
Pyrrole propyl ether (pyriproxyfen) chemical name: 4-phenoxy phenyl (RS)-2-(2-pyridine radicals oxygen) propyl ether, molecular formula: C
20H
19NO
3, it is the insect growth regulator, IGR that the phenylate class upsets insect growth that the pyrrole propyl ether belongs to, and belongs to the novel pesticide of juvenoid, absorbs in having and moves activity, low toxicity, the lasting period is long, and to crop safety, to the fish low toxicity, the characteristics little to eco-environmental impact.Bemisia tabaci, scale insect, diamond-back moth, beet armyworm, prodenia litura, pear psyllid, thrips etc. are had good control efficiency, and this product has good control efficiency to sanitary insect pests such as fly, mosquitoes simultaneously.Have mosquito, fly larvae pupation and the emergence effect of inhibition.Mosquito, fly larva contact this medicament, all in death in pupa time, can not sprout wings basically.This medicament lasting period reached about 1 month, and easy to use, and free from extraneous odour is kill mosquito preferably, fly medicine.
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 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 and will can produce good synergistic effect behind spiral shell worm ethyl ester and MTI-446, the pyriproxyfen compound, and still unexposed about the relevant report of spiral shell worm ethyl ester and MTI-446, pyriproxyfen compound.

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Earlier by Toxicity Determination, 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 is diluted to five series concentration during test, places beaker standby 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 soaked in the soup that configures behind the 5s take out, dry naturally, put into insect box, connect then for the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times, every to repeat used examination borer population be 50, 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 considered as invalid test greater than 10%.Computing formula is as follows:
The insect corrected mortality is converted into probit value (y), and concentration for the treatment of (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 following (be standard medicament with spiral shell worm ethyl ester, its toxicity index is 100):
TI * the P of the theoretical toxicity index (TTI) of M=spiral shell worm ethyl ester
Spiral shell worm ethyl esterTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
P
Effective active composition BBe effective active composition B shared ratio in composition
P
Spiral shell worm ethyl esterBe spiral shell worm ethyl ester shared ratio in composition
