Abstract
The invention discloses an inset and mite killing composition containing xiaochongliulin and spirodiclofen. The inset and mite killing composition comprises xiaochongliulin, spirodiclofen and ordinary pesticide additives, wherein the weight ratio of xiaochongliuli to spirodiclofen is (40:1) to (1:40); the weight sum of xiaochongliulin and spirodiclofen accounts for 1-85% of the composition in percentage by weight. A great deal of indoor and outdoor experiment shows that the insect and mite killing composition has a remarkable synergistic interaction function, the insecticidal spectrum is widened, various insects such as red spiders and scale insects of the agriculture industry can be prevented and treated, the use amount of pesticide is reduced, the residual amount of pesticide on crops is reduced, the pollution to the environment is reduced, and the drug resistance of pests is delayed.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically a kind of with sulfur-phosphor and spiral shell mite ester for active ingredient insecticide acaricide composition.
Background technology
Sulfur-phosphor: belong to organophosphorus insecticides, the mechanism of action is the inhibitor of acetylcholinesterase.Good control efficiency is had to insects such as citrus red mite, arrowhead scales, cotton cotton bollworm, vegetables oriental tobacco budworm, diamond-back moth and rice fulgorids.
Spiral shell mite ester: be a kind of spirocyclic tetronic acid class miticide, the mechanism of action is suppress the Fatty synthesis of mite, blocks the energy metabolism of mite, thus causes evil mite dead.Can be used for the control of evil mite on the solanaceous crops such as fruit tree and eggplant, capsicum, tomato.In addition, also have insects such as pear sucker, oystershell scale and leafhopper classes and well doublely control effect.
The resistance problems of pest is global problems, is the emphasis problem that agricultural science and technology worker pays close attention to always.Along with the impact on the continuity year in year out of Chemical Control of Harmful Insects, the increase of Pesticide use amount and the not factor such as scientifical use agricultural chemicals, cause pest resistance day by day serious, the pest species producing resistance is on the increase.Meanwhile, due to the use agricultural chemicals of high strength, result in that Practice for Pesticide Residue in Agricultural Products exceeds standard, the series of problems such as contaminated environment and the increase of peasant's drug cost, be unfavorable for the sustainable development of agricultural.
Therefore, development is efficient, low toxicity, low-residual, the different mechanism of action, have again the complex preparation of synergistic function simultaneously, not only contribute to the generation delaying pest resistance to insecticide, but also the service life of pesticide species can be extended, reduce using dosage, cost-saving, reduce the pollution to environment.
The compounded formula screening of the present inventor to sulfur-phosphor and spiral shell mite ester conducts in-depth research, find that sulfur-phosphor and spiral shell mite ester carry out composite, within the scope of certain compound proportion, there is obvious synergistic function, in actual use simultaneously, expand insecticidal spectrum, to insect agriculturally, as two spotted spider mite, scale insect etc. have outstanding control efficiency, after further study, the present invention is completed.
Summary of the invention
The object of the present invention is to provide a kind of insecticide acaricide composition containing sulfur-phosphor and spiral shell mite ester, this insecticide acaricide composition has obvious synergistic function, expands insecticidal spectrum, can be used for the various pests such as two spotted spider mite, scale insect of preventing and treating agriculturally.
Another object of the present invention is to the insecticide acaricide composition containing sulfur-phosphor and spiral shell mite ester, the generation that in use can reduce dosage, reduce the residual quantity of agricultural chemicals on crops, delay pest resistance to insecticide, it can also be made to be used alone to compare than single dose to the control efficiency of various insect and to significantly improve, laborsaving, economical, reduce farmer's burdens.
Technical solution of the present invention: a kind of insecticide acaricide composition containing sulfur-phosphor and spiral shell mite ester, active ingredient is sulfur-phosphor and spiral shell mite ester, the weight ratio of sulfur-phosphor and spiral shell mite ester is 40:1 ~ 1:40, sulfur-phosphor and spiral shell mite ester weight summation percentage by weight are in the composition 1 ~ 85%, and all the other are allow in agricultural chemicals to use and acceptable insecticides adjuvant.
Described insecticides adjuvant is one or more the combination in solvent, emulsifier, wetting agent, dispersant, stabilizing agent, antifreezing agent, thickener, disintegrant, binding agent, defoamer, bleeding agent, synergist, fire retardant, macromolecule cyst material, pH adjusting agent and filler, above material is known substance conventional in pesticidal preparations, change to some extent according to being prepared into the different formulations of pesticide, but be not particularly limited, describe no longer one by one at this.
Insecticide acaricide composition of the present invention can be prepared into any one formulation that applicable agricultural production uses by known method, reasonable formulation has suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wetting powder, ultra low volume liquids, microcapsule suspending agent and thermal fog etc.
Insecticide acaricide composition of the present invention can be used for the various pests of preventing and treating agriculturally, as two spotted spider mite, scale insect etc.
The frequency of administration of insecticide acaricide composition of the present invention and amount of application change with crops, insect, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
Compared with prior art, the invention has the advantages that:
1, sulfur-phosphor and spiral shell mite ester is composite has synergistic function, is used alone the control efficiency significantly improved insect, expands insecticidal spectrum simultaneously, solve the defect to some insect weak effect when single dose is used alone than single dose.
2, sulfur-phosphor and spiral shell mite ester two kinds of active ingredients composite, decrease Pesticide use amount, reduce use cost, alleviate pollution to environment, delayed the generation of pest resistance to insecticide, add the service life of agricultural chemicals.
Embodiment
In order to understand essence of the present invention better, below in conjunction with embodiment, content of the present invention is described further, but can not limitation of the present invention be considered as.
(1) Formulation Example
In following each embodiment, active ingredient adopts the former medicine of 90% sulfur-phosphor and the former medicine of 98% spiral shell mite ester, and each component percentages is weight percentage.
Embodiment 1:30% sulfur-phosphor spiral shell mite ester suspending agent
