The invention discloses an insecticidal composition containing pyridalyl and cyhalodiamide. The insecticidal composition contains pyridalyl, cyhalodiamide and pesticide auxiliaries, wherein the weight ratio of pyridalyl to cyhalodiamide is (1 to 10) to (10 to1), and the weight percentage of the total weight of pyridalyl and cyhalodiamide in the composition is 1%-80%; the compounding of pyridalyl and cyhalodiamide has obvious synergism to rice-stem borer and rice leaf folder; and the insecticidal composition can be prepared into common pesticide application dosages including suspending agents, wettable powder, water dispersible granules, missible oil and the like, and is used for preventing and treating pests such as rice-stem borer, and rice leaf folder.
Description
Technical field
The present invention relates to a kind of Pesticidal combination containing pyridalyl and chlorine fluorine cyanogen insect amide, for insects such as water prevention chilo suppressalis, rice leaf roller.
Background technology
Pyridalyl (pyridalyl) former medicine is by SUMITOMO CHEMICAL pesticide developing, and be mainly used in control lepidoptera pest, this medical instrument has active high, and the features such as low-residual, antagonism lepidoptera pest has remarkable control efficiency.
Chlorine fluorine cyanogen insect amide is chlorine fluorine cyanogen insect amide is a kind of phthalic diamides insecticide that Zhejiang Provincial Chemical Engineering Research Inst autonomous innovation in 2010 is researched and developed, the mechanism of action mainly suppresses insect Buddhist nun fish fourth acceptor, its insecticidal spectrum mainly lepidoptera pest, the especially snout moth's larva of rice.
Rice-stem borer belongs to lepidoptera pest, and main boring eats into hazard rice plant, causes the withered heart of paddy rice, huge on rice yield impact, is common general the property insect in China paddy rice producing region.
Rice leaf roller main harm rice plant blade, it is main for taking food blade, harm seriously causes rice leaf large area leaf roll, have a strong impact on the accumulation of rice plant photosynthesis and normal plants, adult and nymph to be all clustered on the stem stalk of rice clump bottom thorn and to inhale juice, meet agitation and namely jump overboard or flee from, hinder nutriment to transport and the viral disease that spreads disease, there is the serious time in insect pest, the output of serious threat grain.
The mixture of different pesticide species is the common methods of preventing and treating agriculture disease pest and weed.Being screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the drug-fast generation of disease pest and weed, is the important means that agricultural synthesis is administered.The recipe determination of the present inventor to pyridalyl and chlorine fluorine cyanogen insect amide conducts in-depth research, find that pyridalyl and chlorine fluorine cyanogen insect amide carry out mixture and have obvious synergistic effect in certain mixed ratio scope to rice-stem borer, rice leaf roller, after further study, the present invention is completed.
Composition and the application of pyridalyl and chlorine fluorine cyanogen insect amide there is no report at present.
Summary of the invention
The object of the invention is to solve in prior art to insect develop immunity to drugs problem and actual control efficiency poor, there is provided a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the Pesticidal combination of the integrated pest management such as rice-stem borer and rice leaf roller.
For solving the problem, the technical solution adopted in the present invention is: a kind of Pesticidal combination containing pyridalyl and chlorine fluorine cyanogen insect amide, active ingredient is pyridalyl and chlorine fluorine cyanogen insect amide, the weight ratio of pyridalyl and chlorine fluorine cyanogen insect amide is 1:10 ~ 10:1, and pyridalyl and chlorine fluorine cyanogen insect amide weight summation in the composition percentage by weight are 1% ~ 80%.
Pesticidal combination provided by the invention utilizes known production technology, select suitable insecticides adjuvant to make comprises the common pesticides application formulation such as suspending agent, wetting powder, water dispersible granules, missible oil.
The auxiliary agent used in Pesticidal combination provided by the invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, pH adjusting agent, defoamer, antifreezing agent, deionized water, filler etc., be all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption are determined by simple test according to recipe requirements.
The production technology of the various application forms of Pesticidal combination provided by the invention all belongs to existing known technology, does not repeat them here.
Pesticidal combination provided by the invention, should in insect egg hatching peak period to the dispenser of low instar larvae phase when for water prevention chilo suppressalis, rice leaf roller, and the dispenser of general employing spray-on process, also can adopt other operation techniques agriculturally applied as required.
Pesticidal combination provided by the invention has following beneficial effect:
1, Pesticidal combination provided by the invention, shows obvious synergistic effect in certain ratio range, and the insecticidal effect of composition is significantly improved than single dose, reduces the using dosage of agricultural chemicals, reduces drug cost.
2, the active ingredient mechanism of action of Pesticidal combination provided by the invention is different, and the application of composition can delay or overcome the generation of pest resistance to insecticide, is conducive to the comprehensive regulation of insect.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these embodiments.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
