Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of Pesticidal combination on crop pest that contains pyridalyl and pyrethroid.
Technical background
Pyridalyl (Pyridalyl) chemical name: 2-[3-[2,6-two chloro-4-[(3,3-two chloro-2-acrylic) the oxygen base] phenoxy group] propoxyl group]-5-(trifluoromethyl) pyrimidine, molecular formula: C
32H

3Pyridalyl has and has the diverse structure of insecticide now, and the many lepidoptera pests on vegetables and the cotton are had remarkable insecticidal activity.Have simultaneously the effect of tagging with stomach toxicity, lepidoptera pest is had original preventive effect, and pyridalyl is very little on various arthropodan impacts, so it is expected to become an effective instrument in integrated pest management.
Pyrethroid is the broad spectrum pesticide that a class can be prevented and treated various pests, and its insecticidal toxicity improves 10 ~ 100 times than older generation insecticide such as organochlorine, organic phosphor, carbamates.Pyrethroid has strong action of contace poison to insect, and some kind has stomach toxicity or fumigation action concurrently, but does not all have systemic action.Its mechanism of action is to upset the normal physiological of insect nerve, makes it by excited, spasm death to benumbing.Pyrethroid is little because of consumption, working concentration is low, thus safer to people and animals, very little to the pollution of environment.Its shortcoming mainly is high to fish toxicity, and some beneficial insect is also had injury, reuses for a long time also to cause insect to develop immunity to drugs.
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.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, synergy ratio very high composite just still less.Through inventor's research, discovery is mutually composite with pyridalyl and gamma cyhalothrin, ether chrysanthemum ester, decis, Biphenthrin, fenpropathrin, tefluthrin, good synergistic effect is arranged within the specific limits, and relevant composite about pyridalyl and gamma cyhalothrin, ether chrysanthemum ester, decis, Biphenthrin, fenpropathrin, tefluthrin there is not yet relevant report at present at home and abroad.

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.First 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 respectively beaker for subsequent use.Adopt and to soak first the method that connects worm behind the leaf, the blade of the same size that does not contact any medicament soaked in the liquid that configures behind the 5s take out, naturally dry, put into insect box, then connect 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 simultaneously blank, 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:
Borer population alive behind borer population-medicine alive before the medicine
Lethality (%)=------------* 100
Borer population alive before the medicine
Processed group lethality-control group lethality
Corrected mortality (%)=---------------* 100
100-control group lethality
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 thus the value of every kind of medicament.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula following (take pyridalyl as the standard medicament, its toxicity index is 100):
