Abstract
The invention relates to an insecticidal combination containing o-phenylenediamine insecticide and flubendiamide. The insecticidal combination is characterized in that active components in the insecticidal combination are o-phenylenediamine insecticide A and flubendiamide, and the remaining is auxiliary ingredients for preparing pesticide formulations, wherein the weight part ratio of the active component o-phenylenediamine insecticide A to flubendiamide is (1-30):(1-35). The pesticide formulations capable of being formed by the insecticidal combination are wettable powder, a suspending agent, soluble liquid, emulsion in water and water dispersible granules. The active components o-phenylenediamine insecticide A and flubendiamide account for 5-40% of the total weight parts of the pesticide formulations. The two effective active components o-phenylenediamine insecticide A and flubendiamide in the combination have obvious synergistic effects, the insecticidal spectrum is expanded, the pesticide amount is reduced, the preventing effect is improved, residue is less, and the insecticidal combination is long in duration and favorable for delaying pesticide resistance of pests and environmental protection.
Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing o-phenylenediamine insecticides and fipronil bisamide.
Background technology
The chemical structural formula of o-phenylenediamine insecticides A is as follows:
，
This insecticide is the new type disinsection immunomodulator compounds that Syngenta Co., Ltd announces, and disclosing its mechanism of action is at present ryanodine receptor agent, without more Experimental report or open, does not also have the site test in composite field open.
Fipronil bisamide mainly activates blue Buddhist nun's alkali acceptor, and the calcium ion of release smooth muscle and the interior storage of striated muscle cell, causes muscle to regulate weak, paralysis, until last insect death.This active ingredient shows mammal and the extremely significant selective difference of insect blue Buddhist nun's alkali acceptor, substantially increases mammal and other vertebrate safeties.O-formammidotiazol-benzamide insecticide all has good control effects to lepidopterous Noctuidae, Pyralidae, Carposinidae, tortricid, miller section, diamond-back moth section, Gracilariidae etc., can also control the multiple non-lepidoptera pests such as coleoptera Culculionidae, Chrysomelidae, diptera Agromyzidae, Bemisia tabaci.Have very outstanding preventive effect to larva, shortcoming is to adult controlling limited efficiency, does not have ovicidal action, and Uptake and translocation effect is not strong.
The insecticide that Long-Time Service is single, insect is easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field is more single.And research and develop the agricultural chemical compound that seems, then the R&D cycle is long, and screening compounds arrangement works is very numerous and diverse, and non-general research and development institution can bear.But the different mechanism of action and without the insecticide rational mixture by a certain percentage of cross resistance, crop disease prevention effect can be improved, reduce dosage, residual few, reduce environmental pollution, effectively reducing the pesticide resistance of crop, is the study hotspot of current medium and small research and development institution.
