preparation example 1

[0085] Preparation 1: 44% binary (10:1) suspension concentrate

[0086] 44% active ingredient (40.0% compound (1) and 4.0% thiacloprid), 2.0% alkylnaphthalene sulfonate, 4.0% polymer carboxylate, 2.0% phenolsulfonic acid condensate sodium salt, carboxymethyl Sodium cellulose 0.5%, glycerin 2.0%, potassium sorbate 0.4%, organic silicon defoamer 0.2%, distilled water added to 100%, put into a high-shear homogeneous emulsifier and shear at high speed for 30 minutes, Then transport it to a sand mill, and circulate the sand for 2-3 times to obtain 44% binary (10:1) suspending agent.

preparation example 2

[0087] Preparation 2: 42% binary (20:1) emulsion in water

[0088] 42% active ingredient (40.0% compound (1) and 2.0% thiacloprid), 4.0% phenethylphenol polyoxyethylene ether phosphate, 6.0% alkyl ammonium salt, 10.0% methyl oleate, cyclohexyl Ketone 5.0%, propylene glycol 5.0%, distilled water to make up to 100%, fully mixed and sheared to obtain 42% binary (20:1) water emulsion.

preparation example 3

[0089] Preparation 3: 50% binary (1:1) suspension concentrate

[0090]50% active ingredients (25.0% compound (1) and 25.0% thiacloprid), 2.0% alkylnaphthalene sulfonate, 1.0% fatty alcohol polyoxyethylene ether sulfate, 4.0% polymer carboxylate, yellow Raw gum 0.05%, ethylene glycol 4.0%, phenyl salicylate 0.4%, silicone defoamer 0.2%, tap water added to 100%, put into a high-shear homogeneous emulsifier for 30 minutes at high speed, Then transport it to a sand mill, and circulate the sand for 2-3 times to obtain 50% binary (1:1) suspending agent.

Abstract

The present invention relates to an insecticidal composition comprising active components (a) and (b) with synergistically effective amounts, the component (a) is compound (1), the component (b) is thiacloprid, and the weight ratio of component (a) to (b) is most preferably 10:1. The insecticidal composition may also contains active component triflumuron (c) with a synergistically effective amount, and the weight ratio of component (a) to (b) to(c) is most preferably 10: 1: 1: or 10: 1: 3. Compared with a single active component, by compounding of the two or three active components, a synergistic effect can be produced, the insecticidal composition can effectively prevent Lepidoptera pests such as diamondback moth, Pieris rapae, beet armyworm, rice Leaffolder or rice planthopper, at the same time, the insecticidal composition can reduce the amount of the active components and prolongs the development of insect pest resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition with synergistic insecticidal effect, its use as an insecticide for preventing and controlling animal pests, and a method for controlling animal pests. Background technique [0002] Lepidoptera pests are the second largest order in Insecta after Coleoptera, and also the order with the most agricultural and forestry pests, such as rice leaf roller, diamondback moth, cabbage caterpillar, beet armyworm, etc. are the most common lepidoptera order pests. The rice leaf roller is one of the main pests of rice. The harm characteristic of the rice leaf roller is that the larvae damage rice, attach leaves to form longitudinal bracts, hide in them and feed on the upper epidermis and mesophyll, leaving only the white lower epidermis, and white spots appear on the insect bracts. White. The damage at the seedling stage affects the normal growth of rice...
