Embodiment 1

[0029] A kind of insecticidal composition of the present invention is made up of dinotefuran and pyridifenthion, and the mass ratio of described dinotefuran and pyridifenthion is 1: (1~20), and preferred scheme is 1: (2 ~10). The insecticidal composition of the present invention can be used to prepare pesticides such as suspension concentrates and wettable powders for spraying on crops.

[0030] When preparing the pesticide dosage form of suspension concentrate, it includes 5-30% of solvent and co-solvent, 5-20% of wetting agent, 5-20% of dispersing agent, 1-10% of viscosifying agent and 0.2-8% of defoaming agent according to mass percentage , 2-10% of antifreeze, and 20-60% of the insecticidal composition. When preparing the wettable powder dosage form, it includes 5-30% of wetting agent, 5-10% of dispersant, 15-75% of filler and 20-60% of the insecticidal composition according to mass percentage.

[0031] Further enumerate 4 specific embodiments below, enumerate as follows...

Embodiment 5

[0035] Weigh 4 g of dinotefuran, 28 g of pyridazinate, 5 g of sodium dodecylbenzenesulfonate, 5 g of alkylphenyl polyethylene glycol ether, 15 g of alkylphenol polyoxyethylene phosphate, and 43 g of kaolin. After the components are fully mixed, they are ground by an airflow machine to obtain a 32% wettable powder.

[0036] Further enumerate 3 specific embodiments below, enumerate as follows with the form of table 2:

[0037] Different examples of table 2 prepare wettable powder pesticide insecticide

Abstract

The invention discloses an insecticidal composition and pesticide therefore as well as an application, and belongs to the pesticide field. The invention provides the insecticidal composition prepared from dinotefuran and pyridaphethione, also provides the pesticide of the insecticidal composition for preparing different dosage forms, and also provides the application of the pesticide on field prevention and cure. The compound insecticidal composition disclosed by the invention is the effective ingredient compound composition of the brand-new pesticide, and the pesticide of suspending agent or wettable powder prepared from the composition has a good prevention and cure effect on field insect pests, and is far higher than the use effect of any one of two components. According to the scheme, the problem of drug resistance of the dinotefuran in the prior art is solved, the drug use amount is lowered, the generation of the drug resistance is delayed, meanwhile, the insecticidal spectrum is enlarged, the cost is lowered, and the invention especially has an obvious prevention and cure effect on insect pests, such as chilo suppressalis, plant hoppers and strawberry aphids.

Description

technical field [0001] The invention relates to a pesticide, in particular to an insecticidal composition using the compound of dinotefuran and pyridazinon as an active ingredient, the pesticide and its application. Background technique [0002] Pyridazinphos, the chemical name is O-(1,6-dihydro-6-oxo-1-phenyl-3-pyridazinyl)-O,O-diethyl phosphorothioate, high efficiency, low Toxic, low residue, broad-spectrum organophosphate insecticide. With contact and stomach poisoning effect, no systemic effect. It has a good control effect on a variety of piercing-sucking mouthparts and chewing pests. Pyridafenthion is used to control common insect pests of rice and cotton, and also has good control effects on various pests of vegetables, wheat, oilseeds, miscellaneous grains, fruit trees, forests and other crops. Pyridafenthion is a low-toxic organophosphorus pesticide that is safe to use. As the country bans five highly toxic organophosphorus species, pyridafenthion is one of the i...
