Abstract
The invention discloses a pesticidal composition, the effective active components of which are pymetrozine and ethiprole. The weight ratio of the pymetrozine to the ethiprole is 1:2-12.5:1, preferably1:2-5:1. The pesticidal combination has the advantages of reasonable components, excellent pesticidal effect, low cost, high quick-acting performance, long persistence, less residue, no pollution tocrops and high safety; wherein the activity and pesticidal effect of the pesticidal composition are not simply overlaying activities of all components, but has remarkable synergy; in addition, the pesticidal composition can slow the generation of drug resistance, meet safety requirements for pesticides and is especially suitable for the prevention and the treatment of rice planthopper.
Description
Technical field
The present invention relates to a kind of Pesticidal combination, particularly Pesticidal combination of being made up of pyrrole aphid ketone and second worm nitrile of effective active composition and uses thereof belongs to technical field of compounded pesticide.
Background technology
Pyrrole aphid ketone (english common name pymetrozine, chemical molecular formula C

5O) mechanism of action is adult with after nymph contacts, and produces the lancet blocking effect, stops to get food and causes harm, hungry causing death.The characteristics of control are that speed of action is slower, lasting period is long, does not have cross resistance with its existing numerous insecticides, can prevent and treat most of homoptera pest, especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect are applicable to vegetables, paddy rice, cotton, fruit tree and multiple field crop.But in actual application, use pyrrole aphid ketone list agent quick-acting relatively poor separately, insect easily produces resistance.
Second worm nitrile (english common name ethiprole, chemical molecular formula C

4OS) be a kind of novel pyrazole insecticides, insecticidal spectrum is wide, and its mechanism of action is to disturb chloride channel by γ-An Jidingsuan (GABA), thereby destroy central nervous system (CNS) normal activity insect is caused death.This medicine is tightr to the white clothing constraint comparison vertebrate of insect GABA chloride channel, thereby very high selection toxicity is provided.Its mechanism of action is different from main insecticide families such as pyrethroid, organic phosphor, carbamate, does not almost produce the chance of interactivity with the existing insecticide of majority.Therefore, it is the desirable reserve kind of resistance management, can be with the mixed pesticide of other chemical family, be used alternatingly.In actual application, use the agent of second worm nitrile list separately, it is fast to have quick-acting, the advantage that resistance is low, but have the high defective of use cost.
At present, be that the pesticidal preparations of effective ingredient is based on 25% pyrrole aphid ketone wetting powder and suspending agent, in actual use with pyrrole aphid ketone, lasting period is long, but quick-acting is relatively poor, and second worm nitrile quick-acting is better, to crop safety, the unexpected discovery of inventor is mixed two active components to use and can improves its quick-acting, lasting period is preferably arranged again, and significantly synergistic effect can reduce the pharmacy application amount, save cost, the generation that slows down pest resistance.
Summary of the invention
One of purpose of the present invention is to provide a kind of good disinsection effect, and drug cost is low, the Pesticidal combination that contains pyrrole aphid ketone and second worm nitrile that is difficult for developing immunity to drugs.
Another purpose of the present invention is to provide the purposes of above-mentioned composition in preventing and treating the rice hoppers insect.
In order to overcome the defective of existing single component formulations, technical scheme of the present invention is to solve like this:
