Embodiment 1

[0034] The control effect of active ingredient A (trifluopyrim) and active ingredient B (one of matrine, azadirachtin and pyrethrin) on pest control was studied by indoor toxicity test.

[0035] Drugs to be tested: trifluoropyrimidine, matrine, azadirachtin, and pyrethrins.

[0036] Dissolve trifluoropyrimidine, matrine, azadirachtin, and pyrethrins in acetone, respectively, and prepare 10,000 mg / L mother solutions, and store them in the refrigerator at 4°C for later use.

[0037] Insects to be tested: Cereal aphid.

[0038] test methods:

[0039] (1) Indoor toxicity assay method

[0040] Taking Aphid spp. as the test material, the toxicity of active ingredient A, active ingredient B and their mixed preparations was determined by the method of soaking insects.

[0041] Single-dose toxicity assay method:

[0042] Using the worm soaking method, first prepare the test agent (including active ingredient A, active ingredient B) with acetone into a 10000mg / L mother solution, and...

Embodiment 2

[0069] 5.5% Trifluoropyrim·matrine suspension concentrate

[0070] Components are composed as follows (each component is by weight percentage):

[0071] Trifluoropyrimidine 5%, matrine 0.5%, alkyl naphthalene sulfonate sodium formaldehyde condensate (dispersant) 5%, castor oil polyoxyethylene ether (dispersion wetting agent) 3%, fatty alcohol polyoxyethylene ether (dispersion wetting agent) 5%, sodium methylene bis-naphthalene sulfonate (wetting agent) 3%, xanthan gum (thickener) 2%, glycerol (antifreeze agent) 4%, water is added to 100%.

[0072] The preparation method is as follows: fully mix the active ingredients, various additives and water in proportion, put them into a sand mill, grind to a particle size of 5 μm, and prepare a 5.5% trifluoropyrim-matrine suspension concentrate.

[0073] The insecticide composition is applied to prevent and control wheat aphids, and is sprayed with different concentrations mixed with water when the pests enter the early blooming stage....

Embodiment 3

[0078] 11% trifluoropyrim · azadirachtin water dispersible granules

[0079] Components are composed as follows (each component is by weight percentage):

[0080] Trifluoropyrimidine 10%, azadirachtin 1%, alkyl naphthalene sulfonate sodium formaldehyde condensate (dispersant) 5%, sodium lignin sulfonate (dispersant) 5%, sodium methylene bis-naphthalene sulfonate ( Wetting agent) 2%, ammonium sulfate (disintegrant) 3%, white carbon black (filler) 30%, calcium carbonate (filler) to make up to 100%.

[0081] The preparation method is as follows: fully mix each active ingredient, alkylnaphthalene sulfonate sodium formaldehyde condensate, wetting agent, disintegrating agent, and filler in proportion, and pulverize it with a jet mill to a particle size of 5 μm to obtain the mother powder. Fully mixed with sodium lignosulfonate, then granulated, dried and sieved to obtain 11% trifluoropyrim·azirachtin water-dispersible granules.

[0082] The insecticide composition is applied to pr...

Abstract

The invention discloses a trifluoropyrim-containing synergistic insecticide composition and an application thereof, belonging to the technical field of pesticides. The insecticide composition of the present invention comprises two active components A and B, wherein the active component A is trifluoropyrim, and the active component B is one of the botanical pesticides matrine, azadirachtin and pyrethrin. In the insecticide composition of the present invention, the action mechanism of the active ingredient A and the active ingredient B are completely different, and the combination can synergize the pests, improve the control effect, reduce the amount of pesticide use, delay the generation of drug resistance, and reduce the risk of drug resistance. It can be used for the control of piercing-sucking mouthparts such as wheat aphid, cotton aphid, corn aphid, bean aphid, potato aphid, apple cotton aphid, tomato whitefly, brown planthopper, brown planthopper, and green leafhopper.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic insecticide composition containing trifluoropyrimidine and its application. Background technique [0002] In recent years, with the changes in farming and cultivation systems, the occurrence of pests has increased year by year, and crop yield and quality have been seriously affected. Chemical insecticide is the most economical and effective means of pest control. The application of insecticides to control pests is of great significance in recovering crop yield losses and improving the commerciality and quality of agricultural products. [0003] Triflumezopyrim is a new mesoionic insecticide developed by DuPont. The compound acts on acetylcholine receptors, but it is different from neonicotinoid insecticides, and is the only compound that acts on nicotinic acetylcholine receptors, that is, nicotinic acetylcholine receptor inhibitors. After insects ar...
