Abstract

The invention relates to an insecticidal combination containing benclothiaz and imidacloprid. The insecticidal combination is characterized in that active components of the insecticidal combination are benclothiaz and imidacloprid, and the remaining are auxiliary components for preparing pesticide formulations. The weight part ratio of the active component benclothiaz to imidacloprid is (3-30):(5-30). The pesticide formulations capable of being prepared from the insecticidal combination comprise wettable powder, suspending agent, soluble liquid, emulsion in water and water dispersible granules. The total weight part of the active components benclothiaz and imidacloprid in the pesticide formulations accounts for 5-40% that of the formulations. The combination contains the two effective active components benclothiaz and imidacloprid and can be prepared into the preparations suitable for agricultural application. The insecticidal combination has an obvious synergistic effect, the insecticidal spectrum is expanded, the pesticide amount is reduced, the control effect is improved, residue is less, the duration is long, and the insecticidal combination is favorable for delaying pesticide resistance of pests and environmental protection.

Description

A kind of Pesticidal combination containing benclothiaz and Imidacloprid
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing benclothiaz and Imidacloprid.
Background technology
Benclothiaz is considered to nematocide usually, thinks the highest to nematode activity, and since compound structure is announced, seldom see the activity research to other field or other insects, the more rare application in agriculture chemical compounding field, its chemical structural formula is as follows:
Imidacloprid 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.Imidacloprid is through extensive application in recent years, and insecticidal effect obviously declines.
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.
