Description

A kind of containing chlorantraniliprole and Tolfenpyrad composition pesticide and uses thereof
Technical field
The present invention relates to a kind of containing chlorantraniliprole and Tolfenpyrad composition pesticide, the invention still further relates to Rynaxypyr and Tolfenpyrad combines for preventing or the purposes of Control pests, and the method for prevention or Control pests, described method comprises co-administered Rynaxypyr and Tolfenpyrad.
Background technology
Chemical control is an important means of the upper prevention of agricultural and Control pests.But current, by kind, the existence characteristic of insect etc., the reasons such as weak effect that living environment etc. cause, repellence prosperity can not effectively be prevented and kill off sometimes.Particularly, to Lepidoptera (Lepidoptera), coleoptera (Coleoptera), Homoptera (Homoptera), thrips (Thysanoptera) insect, utilize conventional dose to carry out prevention and control and just become increasingly difficult.Therefore, for can effectively prevent and kill off can not prevent and kill off or prevent and kill off difficult pest and seek a kind of new means and method.
Rynaxypyr (Chlorantraniliprole) is O-formammidotiazol-benzamide insecticide; the bromo-N-[4-chloro-2-methyl-6-[(of chemical name: 3-methyl-carbamoyl) benzene]-1-(3-chloropyridine-2-yl)-1-hydrogen-pyridine-5-formamide; molecular formula: C18H14N5O2BrCl2; relative molecular weight is: 481, and structural formula is:
Figure 988674DEST_PATH_IMAGE001
Rynaxypyr is the insecticide of a kind of super-active, high-efficiency broad spectrum, the target of effect is ryanodine receptor, Rynaxypyr makes insect ryanodine receptor passage in lasting open state, cause calcium ion and discharge in a large number in sarcoplasmic reticulum chamber, destroyed the stable of the interior environment of Cytoplasmic calcium, thereby make the imbalance of insect contraction of muscle, after effect, insect stops rapidly taking food, occur muscular paralysis, be slow in action, paralysis is until finally dead.Insect, from taking food paralysis, stops harm, only needs the time of about 7 minutes.The different pharmaceutical producing at Rynaxypyr is learned in characteristic, and these change is to be all different from the binding site mediation of ryania on ryanodine receptor by one, and the effect of this insecticide is highly single-minded to insect ryanodine receptor, produces and selects toxicity.Rynaxypyr structure uniqueness, mode of action novelty, insecticidal spectrum is wide, efficient to lepidoptera pest, can control coleoptera Culculionidae, Chrysomelidae, diptera Agromyzidae, the insects such as Bemisia tabaci simultaneously.And Rynaxypyr selectivity is good, to various beneficial insects and natural enemies security, and with used insecticide without cross resistance, be suitable for resistance management and integrated pest management.
Tolfenpyrad (the chloro-3-ethyl-1-of IUPAC:4-methyl-N-{[4-(4-methylphenoxy) phenyl]-methyl }-1H pyrazoles-5-carboxylic acid amides) belong to known commercially available Insecticidal pyrazolines, it is a kind of broad spectrum pesticide.Tolfenpyrad shows excellent insecticidal effect by the oxidative phosphorylation of blocking-up insect, demonstrates for example, broad-spectrum insecticidal activity for various pests (Semiptera (Hemiptera), coleoptera (Coleoptera), diptera (Diptera), Lepidoptera (Lepidoptera), thrips (Thysanoptera) and mite class).Tolfenpyrad mainly provides the prevention and control activity of ovum, larva, pupa and adult to object insect.Its structural formula is as follows:
Figure 217399DEST_PATH_IMAGE002
At present, also do not have about by the report of Rynaxypyr and Tolfenpyrad applied in any combination.
