Abstract
The invention discloses a composite insecticidal composition containing ethiprole and profenofos and an application of the composite insecticidal composition. The ethiprole and the profenofos are used as insecticidal active ingredients of the composite insecticidal composition, wherein the weight ratio of the ethiprole to the profenofos is (0.1-80): (0.5-80). The insecticidal composition is capable of generating a relatively high synergistic effect, overcoming and delaying pest resistance to pesticides and reducing the pesticide cost, high in insecticidal speed, long in lasting period and remarkably high in prevention and control effects in comparison with a single dosage of pesticide. The composite insecticidal composition can be used for preventing and controlling hemiptera pests on crops and particularly preventing and controlling rice planthopper and aphids, and is remarkably high in effect in comparison with the single dosage of pesticide.
Description
Technical field
The invention belongs to the field of agricultural pesticide that contains heterocyclic compound, concrete body relates to a kind of compound pesticide compositions.
Background technology
Second worm nitrile (Ethiprole), chemical name: 1-(2,6-dichlor-4-trifluoromethyl phenyl)-3-cyano group-4-ethyl sulfinyl-5-amino-pyrazol.Molecular formula is: C
13h
9c
12f
3n
4oS.
Second worm nitrile (Ethiprole) is the Insecticidal and acaricidal agent by rhone-poulenc is found, Beyer Co., Ltd develops, belong to effective to multiple chewing type and sucking pest under the low consumption of insecticide that the second generation acts on GABA, can be used for seed treatment and foliar spray, the lasting period reaches 21-28d.(be mainly used in preventing and treating thrips, stinkbug, curculionid, beet gelechiid, aphid, plant hopper and locust etc., some aleyrodid is also shown to activity (particularly the rice grub green rice bug of extremely difficult control being had to very strong activity).
Profenofos (Profenofos) has another name called bromine chlorine phosphorus, many worms phosphorus, and chemical name is: O-(the bromo-2-chlorphenyl of 4-)-O-ethyl-S-propyl group-thiophosphate is broad-spectrum organophosphorous pesticide, has quick-acting.On plant leaf blade, there is good permeability.Its mechanism of action is to suppress cholinesterase in insect bodies.
Former medicine is light yellow liquid, tool is garlicky, 100 ℃/1.80Pa of boiling point, vapour pressure 1.24 * 10^ (4) Pa (25 ℃) density 1.455 (20 ℃), KowlogP=4.44, solvability water 28mg/L (25 ℃), with most immiscible organic solvent, more stable under neutral and micro-sour condition, unstable in alkaline environment.This kind have tag, stomach toxicity and stifling three kinds of modes of action, its insecticidal spectrum is wide, toxicity is lower, efficient equally to above and below ground insect, it is the desirable insecticide of control grain, fruit tree, vegetables and other economic crops insect pests, particularly outstanding to the control efficiency of soil insect, be particularly suitable for the production of pollution-free vegetable.
But the insect such as brown planthopper, aphid is under the condition of current long-term prescription, and resistance increases gradually, and agricultural chemicals single dose declines gradually to the effect of control of insect.Inventor finds after deliberation, and the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, not yet finds up to now the Pesticidal combination of relevant second worm nitrile and Profenofos.
Summary of the invention
The object of this invention is to provide a kind of compound pesticide compositions containing second worm nitrile and Profenofos, this Pesticidal combination is the multifunctional insecticide composition of control Semiptera insect.
Another object of the present invention is to provide this Pesticidal combination and in preparation, prevents and treats the application on the insecticidal materials of resistance Semiptera insect, particularly the application on the insecticidal materials of preparation control plant hopper or aphid.
The object of the invention is to be achieved through the following technical solutions:
Containing a compound pesticide compositions for second worm nitrile and Profenofos, it is main active ingredient that this compound pesticide compositions be take second worm nitrile and Profenofos, and wherein, the weight ratio of second worm nitrile and Profenofos is 0.1 ~ 80:0.5 ~ 80.
In this compound pesticide compositions, the weight ratio of second worm nitrile (A) and Profenofos (B) is preferably 0.5 ~ 50:1 ~ 50.A kind of preferred scheme is that the two weight ratio of A and B is further 0.5 ~ 10:1 ~ 30, most preferably is 1～10:1～10.It is that the two weight ratio of A and B is 0.1～20:1 that another kind is preferably scheme, is further 0.1～10:1.
This compound pesticide compositions can only contain active component second worm nitrile and Profenofos, also can when using or prepare, in active component, add other components, and the effective ingredient in this Pesticidal combination can also synergy effective dose be present in composition.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of second worm nitrile and Profenofos is 3% ~ 80%.Be preferably 5% ~ 55%, most preferably 10% ~ 40%.
Compound pesticide compositions of the present invention be take second worm nitrile and Profenofos and is mixed with any one formulation allowing on agricultural chemicals, the preferred missible oil of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion and water dispersion granule as main active ingredient and insecticides adjuvant and excipient.
Aforementionedly can be applicable to the not special restriction of insecticides adjuvant of the present invention, include, but are not limited to calcium dodecyl benzene sulfonate, 600#, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., aforementionedly can be applicable to excipient of the present invention and be also not particularly limited, include, but are not limited to solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and use.
Multiple Semiptera and lepidoptera pest that compound pesticide compositions of the present invention easily produces resistance to brown planthopper and snout moth's larva etc. have good preventive effect; And suppress insect the pesticide resistance of unitary agent (second worm nitrile or Profenofos are arbitrary) is produced.
Above-mentioned compound pesticide compositions is prevented and treated the application on resistance Semiptera insect insecticidal materials in preparation, and especially the effect on preparation control plant hopper or aphid insecticidal materials is remarkable.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism Semiptera insect, as brown planthopper, aphid etc. has obvious synergistic function, overcomes and has delayed pest resistance to insecticide, and expanding prevention is composed, desinsection speed is fast, has obviously improved control efficiency; (2) reduce control recruitment, drug cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with Profenofos single dose with second worm nitrile, produce and use cost reduction; (6) suppress Semiptera insect the resistance of agricultural chemicals is strengthened, its successful is used higher than its single dose.
