Embodiment 1

[0094] Example 1: (75% dinotefuran·bifenazate wettable powder)

[0095] Composition and content: Dinotefuran, 50%; Bifenhydrazine, 25%; Wetting agent, sodium lauryl sulfate, 2%; Dispersant, calcium lignosulfonate, 8%; Filler silica, more than the amount.

[0096] The preparation method of Example 1 is as follows: according to the components and weight percentages provided in the examples, dinotefuran, bifenhydrazine, dispersant, wetting agent and filler are mixed uniformly, and then mixed with a jet mill to make Get wettable powder. The main equipment includes mixer and jet mill.

Embodiment 2

[0097] Example 2: (60% dinotefuran·bifenazate water dispersible granules)

[0098] Components and content: Dinotefuran, 30%; Bifenhydrazine, 30%; Wetting agent sodium dodecylbenzene sulfonate, 3%; Dispersant alkyl naphthalene sulfonate formaldehyde condensate, 8%; Filler Attapulgite, margin.

[0099] The preparation method of the above example 2 is as follows: according to the components and their weight percentages provided in the examples, mix dinotefuran, bifenhydrazine, dispersant, wetting agent and filler uniformly, pulverize by jet mill and add 10 ~25% water, then kneaded, extruded, granulated, and dried to obtain water dispersible granules. Or the crushed powder is sprayed with water in a boiling granulator, granulated, dried, and then sieved to obtain water dispersible granules. The main equipment is mixer, jet mill, kneader, extrusion granulator, drying room or fluidized bed drying, or boiling granulator, screening machine.

Embodiment 3

[0100] Example 3: (30% dinotefuran·bifenazate oil suspension)

[0101] Components and content: Dinotefuran, 10%; Bifenhydrazine, 20%; Emulsifier Nongyu BY-125, 7%; Nonylphenol polyoxyethylene ether phosphate 8%; Thickener is organic bentonite, The dosage is 1.6%; methyl oleate, the balance.

[0102] The preparation method of the above example 3 is as follows: according to the components and weight percentages provided in the examples, dinotefuran, bifenazate, surfactants and other functional additives are placed in a reactor in turn, and methyl oleate is added. The ester is evenly mixed, subjected to high-speed shearing, wet sanding, and finally homogeneously filtered to obtain an oil suspension. The main equipment is batching kettle, colloid mill or homogenizer mixer, sand mill.

Abstract

The invention belongs to the technical field of agricultural insecticides, and particularly relates to a Dinotefuran / Bifenazate compound insecticidal composition. The effective ingredients are Dinotefuran and Bifenazate in a weight ratio of 2:1-1:3, preferably 1:2. The Dinotefuran / Bifenazate compound insecticidal composition is composed of the effective ingredients with different action mechanisms, so that the action sites are increased, thereby being beneficial to overcoming and postponing the generation of insecticide resistance of insects, and widening the insecticidal spectrum; and the invention greatly enhances the insecticidal effect, has the advantages of long preventive effect time and lower consumption of effective ingredients in the field, lowers the production and use cost, and reduces the insecticide residue and environmental pollution.

Description

Technical field [0001] The invention belongs to the technical field of agricultural insecticides, and particularly relates to a compound insecticidal composition of dinotefuran and bifenazate. Background technique [0002] Dinotefuran (dinotefuran) [0003] [0004] The chemical name of dinotefuran is (RS)-1-methyl-2-nitro-3-[(3-tetrahydrofuran)-methyl]guanidine. It was first developed by Japan's Mitsui Chemicals Co., Ltd. and was listed in 2002 The third-generation nicotinic insecticide. It has a wide insecticidal spectrum, can control many kinds of pests such as Hemiptera, Lepidoptera and Hymenoptera, and has significant systemic and osmotic effect. It shows insecticidal activity at very low doses. The insecticide is very safe to mammals, birds and aquatic organisms, has no phytotoxicity to crops, and can be used for pest control of many crops such as rice, fruit trees and vegetables. But dinotefuran, like many chemical insecticides, will develop resistance if used for long, c...
