Embodiment 1

[0056] water emulsion

[0057] 5.5% Fluonicamid · Flupyrfuranone

[0058] Ratio: flonicamid, 5%; fluroxyfuranone, 0.5%; emulsifier Nongru NP-10, 3%; castor oil polyoxyethylene ether, 2%; phenylphenol polyoxyethylene ether phosphate, 2%; Dimethyldecylamide, 10%; Cyclohexanone, 10%; Ethyl acetate 5%; Antifreeze agent ethylene glycol, 5%; Defoamer silicone compound, 0.2%;

[0059] Preparation method: Dissolve the active ingredients flonicamid and flupirfurone, emulsifier, solvent, and co-solvent according to the above to form an oil phase, and mix water, antifreeze, preservatives, thickeners and other ingredients evenly to form a water phase. Phase; while shearing at high speed in the reactor, add the oil phase dropwise to the water phase, and shear for a period of time to form a stable oil-in-water emulsion.

Embodiment 2

[0061] wettable powder

[0062] 60% flonicamid·flupyrfurone wettable powder

[0063] Proportion: flonicamid, 40%; flupirfuranone, 20%; wetting agent sodium lauryl sulfate, 2%; dispersant calcium lignosulfonate, 8%; filler white carbon black, 18% , filler kaolin, the balance.

[0064] Preparation method: according to the above ratio, add the active ingredients flonicamid and flupyfuranone into the carrier, add surfactants and other functional additives, mix, and then mix after jet crushing to obtain wettability powder. The main equipment is a mixer and a jet mill.

Embodiment 3

[0066] Cream

[0067] 20% flonicamid·flupyrfurone emulsifiable concentrate

[0068] Proportion: flonicamid, 10%; flupirfuranone, 10%; emulsifier chooses Nongru 500# and Nongru OP-10#, the dosage is 4% and 5% respectively; solvent chooses N, N-two Methylformamide, 25%; ethyl acetate, 30%; xylene, the balance.

[0069] Preparation method: Add the active ingredients flonicamid and flupyrfuranone into the carrier according to the above ratio, add surfactant and other functional additives, and stir and mix evenly in a stirring mixing tank. The stirring and mixing kettle can be enamel reaction kettle, stainless steel stirring kettle, etc.

Abstract

The invention provides an agricultural insect-killing composition and application thereof, and relates to the field of pesticides, in particular to the field of insecticides. After effective ingredients of flonicamid and flupyradifurone are compounded, the insect killing effect is obviously improved, the pest resistance risk is small, the cost is low, the drug effect is long, and the pollution to environment is small. The agricultural insect-killing composition comprises the effective ingredients and auxiliary ingredients, wherein the effective ingredients comprise flonicamid and flupyradifurone according to a weight ratio of 1:(0.1 to 10); the weight percentage content of the effective ingredients of flonicamid and flupyradifurone accounts for 1% to 80% of the total weight percentage of the agricultural insect-killing composition; the auxiliary ingredients comprise a carrier and an additive, the carrier is selected from one or more of water, solvent or filler, and the additive comprises at least one surfactant.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the field of insecticides, in particular to an agricultural insecticide composition and its application. Background technique [0002] With the changes in farming systems and the increase in the use of pesticides in large quantities, pesticides with a single active component have narrow insecticidal ranges, poor control effects, and large application doses are prone to phytotoxicity and drug resistance. Many disadvantages such as frequent application and increased environmental pollution have obviously led to a large reduction in crop production and a substantial increase in production costs. For the prevention and control of resistant pests in agriculture, one way is to introduce new ingredients that are not mutually resistant to existing ones, but the development cost of new active ingredients is high, the development cycle is long, and they can never keep up with the pests Generated...
