Abstract
The invention discloses an insect-killing composition containing bromantrniliprole and pyrethroid. The insect-killing composition comprises an active component A and an active component B, the active component A is selected from bromantraniliprole, the active component B is any one compound selected from following compounds: high-effective cyhalothrin, ethofenprox, bifenthrin, fenpropathrin, and tefluthrin, and the mass ratio of the active component A to the active component B is 1:80 to 60:1. The insect-killing composition has a high activity on a plurality of insects on a plurality of crops, has a prominent amplification effect, enlarges the insect-killing spectrum, and has the characteristics of small dosage amount, rain washing resistance, and prominent amplification effect.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of Pesticidal combination on crop pest of a kind of brominated worm benzamide and pyrethroid.
Technical background
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 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.
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 is all 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 by bromine worm benzamide and gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin, good synergistic effect is arranged within the specific limits, and relevant composite about bromine worm benzamide and gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin, there is not yet relevant report at present at home and abroad.
Summary of the invention
The objective of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect is good brominated worm benzamide and the Pesticidal combination of pyrethroid.
The Pesticidal combination of a kind of brominated worm benzamide and pyrethroid, it is characterized in that containing active components A and active component B, active components A and active component B weight ratio are 1 ︰ 80 ~ 60 ︰ 1, described active components A is selected from bromine worm benzamide, and active component B is selected from a kind of in gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin.The preferred weight ratio of active components A and active component B is 1 ︰ 60 ~ 40 ︰ 1; More preferably the weight ratio of bromine worm benzamide and gamma cyhalothrin is 1 ︰ 20 ~ 20 ︰ 1, the weight ratio of bromine worm benzamide and ether chrysanthemum ester is 1 ︰ 30 ~ 10 ︰ 1, the weight ratio of bromine worm benzamide and Biphenthrin is 1:30 ~ 20 ︰ 1, the weight ratio of bromine worm benzamide and fenpropathrin is 1 ︰ 30 ~ 5 ︰ 1, and the weight ratio of bromine worm benzamide and tefluthrin is 1 ︰ 20 ~ 20 ︰ 1; The weight ratio that most preferably is bromine worm benzamide and gamma cyhalothrin is 1 ︰ 10 ~ 10 ︰ 1, the weight ratio of bromine worm benzamide and ether chrysanthemum ester is 1 ︰ 15 ~ 5 ︰ 1, the weight ratio of bromine worm benzamide and Biphenthrin is 1:15 ~ 10 ︰ 1, the weight ratio of bromine worm benzamide and fenpropathrin is 1 ︰ 15 ~ 3 ︰ 1, and the weight ratio of bromine worm benzamide and tefluthrin is 1 ︰ 10 ~ 10 ︰ 1.
