Embodiment 1

[0055] Example 1: (1:24.86)

[0056] An insecticidal composition containing dinotefuran and indoxacarb, which is made of the following raw materials in mass fraction:

[0057]

[0058]

[0059] The preparation method of the above-mentioned insecticidal composition preparation containing dinotefuran and indoxacarb, the steps are:

[0060] A. According to the designed formula, weigh dinotefuran and indoxacarb original medicine, put them into a holding container, then add sodium lauryl sulfate, sodium dibutyl naphthalene sulfonate, sodium lignin sulfonate and naphthalene Sulfonate formaldehyde polymer, glycerin, AF9903, light sodium silicate, etc., stir well;

Abstract

The invention relates to an insecticidal composition containing dinotefuran and indoxacarb. The insecticidal composition comprises active ingredients, namely dinotefuran and indoxacarb at a weight ratio of (1:3.57)-(35:1). Due to different active mechanisms, different durable effects and fast-acting properties and different control objects, so that the dinotefuran and the indoxacarb have complementary advantages and are capable of overcoming the defect that resistance is easily generated by continuous selection pressure of single chemicals; experimental data indicates that the dinotefuran and the indoxacarb are relatively high in synergetic effect. The insecticidal composition containing dinotefuran and indoxacarb is capable of reducing the pesticide dosage, reducing the pesticide cost, alleviating the economic burden of farmers, reducing the environmental pollution caused by pesticides, reducing pesticide residues, improving the grain safety, delaying the pesticide resistance generation time of injurious insects, prolonging the service lives of the dinotefuran and the indoxacarb, and enlarging the control objects, and the dinotefuran and indoxacarb preparation has the advantages of safety, high efficiency and application amount reduction.

Description

technical field [0001] The invention belongs to the field of insecticidal technology containing pyridine compounds and neonicotinoid compounds, more specifically relates to an insecticidal composition containing dinotefuran and indoxacarb, and also relates to an insecticidal composition containing dinotefuran and A preparation method of indoxacarb mixed preparation, which is suitable for preventing and controlling piercing-sucking pests brown planthopper, white-backed planthopper, gray planthopper, green planthopper, aphids, whitefly, greenhouse whitefly, leafhopper, rice thrips At the same time, it can also prevent borers, rice leaf rollers, diamondback moths, Spodoptera litura, beet armyworms, rice negative mudworms, rice locusts, scales, yellow striped flea beetles, stinkbugs, etc. Background technique [0002] Brown planthoppers belong to the order Homoptera and belong to the family Planthopper. It is the main pest of rice in my country and Asia, and has the habit of lo...
