The composition provides synergy effects for a plurality of pests harmful for agricultural production, and has characteristics of pesticide consumption reduction, reduction of residual pesticide on crops, environmental pollution reduction, safety to human and animals, good environment compatibility, and pest drug resistance generation resistance.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of Pesticidal combination containing tetrachloro insect amide and pyrethroid on crop pests.
Background technology
Tetrachloro insect amide: compound insecticidal spectrum approaches Rynaxypyr, laboratory's activity, the imitation of leaf roll snout moth's larva and borer is equal to or higher than 20% Rynaxypyr, but use 15 milliliters of meterings/bag higher than Rynaxypyr (equaling 1.5 bag Rynaxypyr doses), so in actual use, extremely worm velocity ratio is very fast, the lasting period is longer.
Gamma cyhalothrin, ether chrysanthemum ester, decis, fenpropathrin and Biphenthrin all belong to pyrethroid insecticides, be the broad spectrum pesticide that a class can be prevented and treated various pests, its insecticidal toxicity improves 10 ~ 100 times than older generation insecticide 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 all there is no 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 because consumption is little, working concentration is low, thus safer to people and animals, very little to the pollution of environment.Its shortcoming is mainly high to fish toxicity, and some beneficial insect is also had to injury, reuses for a long time and also can cause insect to develop immunity to drugs.
But 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 synergy to lack, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.The composite very research of using through inventor, find tetrachloro insect amide and gamma cyhalothrin, ether chrysanthemum ester, decis, fenpropathrin or Biphenthrin can produce good synergistic effect after composite, and not yet open about tetrachloro insect amide and the composite relevant report of gamma cyhalothrin, ether chrysanthemum ester, decis, fenpropathrin or Biphenthrin.
