Nitenpyram and chlorpyrifos methyl contained synergia insecticidal composite and application thereof

Abstract

The invention discloses a nitenpyram and chlorpyrifos methyl contained synergia insecticidal composite and an application thereof. In the insecticidal composite, nitenpyram and chlorpyrifos methyl are taken as active constituents, wherein the weight ratio of the nitenpyram and chlorpyrifos methyl is (0.1-80):(0.5-80). In the insecticidal composite, high synergism can be generated, drug resistance of injurious insect is overcome and delayed, prevention and control spectrum are expanded, the insecticidal speed is rapid, and the medication cost is reduced and toxicity is alleviated. The nitenpyram and chlorpyrifos methyl contained synergia insecticidal composite can prevent and control hemiptera injurious insects on crops, is particularly used for preventing and controlling plant hoppers and wheat aphids of rice, and the effect of the composite is obviously better than that of siple dosage.

Description

technical field

[0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition with nitenpyram and chlorpyrifos-methyl as main active ingredients and its application. Background technique

[0002] Nitenpyram is a neonicotinoid insecticide with the chemical name (E)N-(6-chloro-3-pyridylmethyl)-N-ethyl-N′-methyl-2- Nitroethylenediamine. The structural formula is as follows:

[0003]

[0004] The drug has a wide insecticidal spectrum and is widely used in agriculture and horticulture to control aphids, leafhoppers, thrips, planthoppers and other hemiptera pests. It has low dosage, low toxicity, long-lasting drug effect, no harm to crops, and is safe to use; The drug acts on nicotinic acetylcholine receptors in a unique way, and pests are not easy to develop resistance. It has excellent systemic and osmotic effects, and has a broad market prospect, but its market price is relatively high.
