Description

Pyridalyl and four chlorantraniliprole complex insecticidal compositions
Technical field
The invention belongs to technical field of pesticide combination, specifically, relate to a kind of pyridalyl and four chlorantraniliprole complex insecticidal compositions.
Background technology
Four chlorantraniliproles take Rynaxypyr as the novel anthranilamides that lead compound is developed, belong to ryanodine receptor activator insecticides, be combined by ryanodine receptor in pest body, open calcium channel, make to be stored in intracellular calcium ion sustained release in sarcoplasm, calcium ion and sarcoplasm mesostroma protein combination, cause muscle contracts last.Insect bodies Symptoms is tic, food refusal, finally dead.Four chlorantraniliproles are low toxicity broad spectrum pesticide, all have good activity to lepidoptera pest, as rice leaf roller, and beet armyworm etc.
Pyridalyl (pyridalyl) fluoroform pyrrole ether is the novel dichloropropylene ethers insecticide containing pyridine groups developed by SUMITOMO CHEMICAL KCC.Be mainly used in the lepidoptera pest larva preventing and treating damage to crops, to thrips thrips, diptera leaf miner, also there is good preventive effect in addition.Remarkable insecticidal activity is had to the many lepidoptera pests on vegetables, cotton and fruit tree.Pyridalyl belongs to propylene halide insecticides, is different from the insecticide of other any types existing, has remarkable active to the lepidoptera pest that vegetables and cotton extensively exist.Meanwhile, it is less on many useful arthropods impacts.This compound also shows high insecticidal activity to the sensitive strain of diamond-back moth and resistant strain.
In the real process of agricultural production, using chemical agent is the most effective means of control plant pest, but is the generation of pest resistance to insecticide by the problem that chemical control insect the most easily produces.And use single chemical insecticide continuously for a long time high dose, composite or the mixture of the rational chemical insecticides of series of problems such as residual, the environmental pollution of medicament is easily caused to have expansion insecticidal spectrum, improve control efficiency, extend the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce and remain, delay positive feature such as pest resistance and drug-fast generation and development etc., the composite or mixture of insecticidal/acaricidal agent is one of the effective method the most solved the problem.Develop new product insecticide price constantly rises, and by contrast, exploitation is efficient with research, low toxicity, low-residual composite and mixture has small investment, the lead time is short and be subject to domestic and international attention, numerous and confused increasing develops dynamics.
