Abstract
The invention discloses a kind of Pesticidal combination containing CGA 183893, Pesticidal combination containing active components A and active component B, wherein active components A is selected from CGA 183893, active component B is selected from any one compound following: Imidacloprid, Acetamiprid, second worm nitrile, and the weight ratio of active components A and active component B is 1 ︰ 70 ~ 70 ︰ 1.The various pests of the present composition to harm agricultural production has synergistic effect, and decrease pesticide usage amount, reduce the residual quantity of agricultural chemicals on crop, alleviate environmental pollution, to person poultry safety, Environmental compatibility is good, and insect not easily develops immunity to drugs.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of Pesticidal combination on crop pests containing CGA 183893.
Background technology
CGA 183893 (dicyclanil) chemical name: 4,6-diaminourea-2-cyclopropylamino pyrimidine-5-nitrile, molecular formula: C
8h

6.CGA 183893 interference insect is peeled, and after insect generations Systemic absorption, stops larvae pupation or becomes worm.
Imidacloprid (imidacloprid) chemical name: 1-(6-chloro-3-pyridyl ylmethyl)-N-Nitroimidazoline-2-base amine, molecular formula: C

5o
2.Imidacloprid belongs to nitro-methylene-type systemic insecticide, is the acting body of nicotinic acetylcholine esterase acceptor, and it is malfunctioning that interference pest movements nervous system makes chemical signal transmit, without cross resistance problem.For preventing and treating sucking pest and resistant strain thereof.
Acetamiprid (acetamiprid) chemical name: E-N'-[(6-chloro-3-pyridyl base) methyl]-N^ (2)-cyano group-N'-methylacetamide, molecular formula: C
10h

4.This product has stronger tagging and osmosis, and the longevity of residure is long, has good control efficiency to the aphid of cucumber, apple tree, orange tree.Because mechanism of action is unique, the aphid existing medicament being had to resistance can be prevented and treated.
Second worm nitrile (ethiprole) chemical name: sub-sulphur (sulphur) the acyl group pyrazoles of 5-amino-1-(2,6-dichloro-4-fluoromethylphenyl)-4-ethyl-3-itrile group, molecular formula: C
13h

4oS.Second worm nitrile is novel pyrazole insecticides, and insecticidal spectrum is wide.Disturb chloride channel by γ-aminobutyric acid (GABA), thus destruction central nervous system (CNS) normal activity makes insect lethal.The white clothing constraint comparison vertebrate of this medicine to insect GABA chloride channel is tightr.Thus very high selection toxicity is provided.Its mechanism of action is different from the main insecticide family 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 standby kind of resistance management, can with the mixed pesticide of other chemical family, be used alternatingly.
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 to prevent and treat the very common method of 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 the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.Through inventor's research, find CGA 183893 and Imidacloprid, Acetamiprid, second worm nitrile is composite after can produce good synergistic effect, and not yet open about the relevant report that CGA 183893 and Imidacloprid, Acetamiprid, second worm nitrile are composite.
Summary of the invention
The object of the invention is to propose a kind of to there is the Pesticidal combination containing CGA 183893 that synergistic function, use cost are low, preventive effect is good.The Pesticidal combination that the present invention proposes contains active components A and active component B, active components A and active component B weight ratio are 1 ︰ 70 ~ 70 ︰ 1, described active components A is selected from CGA 183893, active component B is selected from the one in Imidacloprid, Acetamiprid, second worm nitrile, and active components A and the preferred weight ratio of active component B are 1 ︰ 50 ~ 50 ︰ 1; The weight ratio being more preferably CGA 183893 and Imidacloprid is 1 ︰ 30 ~ 15 ︰ 1, and the weight ratio of CGA 183893 and Acetamiprid is 1 ︰ 30 ~ 30 ︰ 1, and the weight ratio of CGA 183893 and second worm nitrile is 1 ︰ 30 ~ 15 ︰ 1.
The described Pesticidal combination containing CGA 183893 is for preventing and treating the purposes of insect on fruit tree, vegetables, cereal crops, fiber crop, legume crop, ornamental plants, lawn, forest.
Described insect comprises: aphid, trialeurodes vaporariorum, leaf miner, pear sucker, rice fulgorid, rice gall midge, tea lesser leafhopper, Bemisia tabaci, thrips, rice leaf roller, cotton bollworm, cotton boll resemble, beet armyworm, rice leafhopper, diamond-back moth.
The weight ratio of active components A, active component B is 1 ︰ 70 ~ 70 ︰ 1.In usual composition, the weight percentage of active component is 0.5% ~ 90% of gross weight, is preferably 5% ~ 80%.According to different preparation types, active component content scope is different.Usually, liquid preparation contains the active substance of by weight 1% ~ 70%, is preferably 5% ~ 50%; Solid pharmaceutical preparation contains the active substance of by weight 5% ~ 80%, is preferably 10% ~ 80%.
At least containing a kind of surfactant in Pesticidal combination of the present invention, the dispersion of active component in water when being beneficial to use.Surface-active contents is 5% ~ 30% of total formulation weight amount, and surplus is solid or liquid diluent.

Table 22 CGA 183893 and active component B and the composite control rose thrips test of pesticide effectiveness thereof
As can be seen from Table 22, CGA 183893 and active component B and composite control rose thrips thereof, control efficiency is all better than the preventive effect of single dose, and the preventive effect phase is long.In test scope of medication, target crop is had no adverse effects.
After draw through tests different local throughout the country, the preventive effect of the common insect pests such as CGA 183893 and Imidacloprid, Acetamiprid, second worm nitrile be composite to be resembled afterwards to the aphid in various crop, trialeurodes vaporariorum, leaf miner, pear sucker, rice fulgorid, rice gall midge, tea lesser leafhopper, Bemisia tabaci, thrips, rice leaf roller, cotton bollworm, cotton boll, beet armyworm, rice leafhopper, diamond-back moth is all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
