Embodiment 1

[0044] Example 1: 33% thiobenzamide·pymetrozine suspending agent (10:1)

[0045] 33% active compound (composition of 30% thiobenzamide and 3% pymetrozine), alkylnaphthalene sulfonate 2%, fatty alcohol polyoxyethylene ether sulfate 1.3%, phenolsulfonic acid condensate sodium Salt 2%, glycerol 2%, butylparaben 0.2%, silicone 0.1%, water to make up to 100%, put into a high shear homogeneous emulsifier for high-speed shearing for 25 minutes, and then pump to sand Sand grinding in a mill for 90 minutes, and after filtration, a suspension containing 33% of the active compound was obtained.

Embodiment 2

[0046] Example 2: 31% thiobenzamide·pirimicarb suspending agent (30:1)

[0047] 31% active compound (composition of 30% thiobenzamide and 1% pirimicarb), alkylnaphthalene sulfonate 2.3%, acyl glutamate 2%, phenolsulfonic acid condensate sodium salt 1% , sodium methylnaphthalene sulfonate formaldehyde condensate 2%, epoxidized soybean oil 5%, glycerol 2%, silicone 0.1%, water to make up to 100%, put into a high-shear homogeneous emulsifier for high-speed shearing 25 minutes, then pumped to a sand mill for sand grinding for 90 minutes, and after filtration, a suspending agent containing 31% of the active compound was obtained.

Embodiment 3

[0048]Example 3: 30% thiobenzamide·isoprocarb suspending agent (2:1)

[0049] 30% active compound (composition of 20% thiobenzamide and 10% isoprecarb), alkylnaphthalene sulfonate 2.6%, acyl glutamate 2%, fatty alcohol polyoxyethylene ether sulfate 1 %, phenolsulfonic acid condensate sodium salt 1.0%, polymer polycarboxylate 2%, sodium starch octenyl succinate 2.4%, glycerol 2%, silicone defoamer 0.1%, deionized water 100%, put into a high-shear homogeneous emulsifier for high-speed shearing for 25 minutes, then pump to a sand mill for sand grinding for 90 minutes, and filter to obtain a suspending agent containing 30% of active compounds.

Abstract

The invention discloses an insecticidal composition for preventing and controlling insect pests with piercing-sucking mouthparts and relates to the technical field of pesticides. The insecticidal composition consists of an insecticidal activity compound I and an insecticidal activity compound II, wherein the insecticidal activity compound I is thiobenzamide with the chemical name of 3-bromo-N-[4-chloro-2-methyl-6-(methylaminothiocarbamoyl) phenyl]-1-(3-chloropyridine-2-yl)-1H-pyrazol-5-formamide; and the insecticidal activity compound II is selected from one of pymetrozine, isoprocarb, fenobucarb, carbosulfan, benfuracarb, pirimicarb, methomyl and meta-tolyl-N-methylcarbamate. The composition disclosed by the invention has an obvious synergistic effect compared with a single insecticide, the insect pests with piercing-sucking mouthparts can be effectively prevented and controlled, the application dosage of the pesticides is reduced, the application cost is saved, the defects of the single insecticide and the tolerance of insect pests on the insecticide are overcome, and the insecticidal activity is improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticidal composition compounded by two insecticidal active compounds, in particular to a piercing-sucking mouthpart pest control compound compounded by thiobenzamide and an insecticidal active compound insecticidal composition. Background technique [0002] Chinese invention patent "thiobenzamide compound and its application", publication number CN103109816A, discloses that the general structural formula 1 of the thiobenzamide compound is: [0003] [0004] The thiobenzamide compounds with the above general formula 1 not only have high activity against lepidopteran pests, but also have unexpectedly high activity against piercing-sucking pests (such as rice planthoppers), and these compounds have good properties. Combined treatment and comprehensive functions. According to the general formula 1, the applicant preferably R1 is chlorine, and R2 is methyl, and the inse...
