Embodiment 1

[0054] water emulsion

[0055] 5.5% Chlorthiazolin Lufenuron Water Emulsion (1:0.1)

[0056] Proportion: chlorothialine, 5%; lufenuron, 0.5%; emulsifier Nongru NP-10, 3%; castor oil polyoxyethylene ether, 2%; phenylphenol polyoxyethylene ether phosphate, 2% dimethyl sulfoxide, 15%; N-methylpyrrolidone, 5%; xylene, 5%; antifreeze ethylene glycol, 5%; antifoaming agent silicone compounds, 0.2%;

[0057] Preparation method: according to the above, the active ingredients chlorothialine and lufenuron, emulsifier, solvent, and co-solvent are dissolved to form an oil phase, and water, antifreeze, preservative, thickener and other ingredients are mixed evenly to form a water phase; Add the oil phase dropwise to the water phase while shearing at high speed in the reactor, and shear for a period of time to form a stable oil-in-water emulsion.

Embodiment 2

[0059] wettable powder

[0060] 60% Chlorthiazolin · Lufenuron WP (1:0.5)

[0061] Proportion: chlorothialine, 40%; lufenuron, 20%; wetting agent sodium lauryl sulfate, 2%; dispersant agent calcium lignosulfonate, 8%; filler silica, 18%, filler Kaolin, balance.

[0062] Preparation method: according to the above ratio, add the active ingredients clothialine and lufenuron into the carrier, add surfactants and other functional additives, mix, and then mix after jet crushing to obtain a wettable powder. The main equipment is a mixer and a jet mill.

Embodiment 3

[0064] Cream

[0065] 10% Chlorthiazolin · Lufenuron EC (1:1)

[0066] Proportion: Chlorthialine, 5%; Lufenuron, 5%; Nongru 500# and Nongru OP-10# are used as emulsifiers, the dosages are 4% and 5% respectively; N, N-dimethyl is used as solvent Formamide, 30%; cyclohexanone, 15%; xylene, the balance.

[0067] Preparation method: according to the above ratio, add the active ingredients chlorothialine and lufenuron into the carrier, 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 insecticide composition and application thereof, relates to the field of pesticides, and in particular relates to the field of insecticides. Effective components, namely imidaclothiz and lufenuron, are compounded, so that the insecticidal spectrum is widened, the prevention and treatment effect on lepidoptera pests is greatly improved, the insecticide effect is remarkably improved, the agricultural insecticide composition is small in pest drug resistance, low in cost, long in medicinal effect lasting and small in environment pollution, and the yield of crops can be remarkably increased. The agricultural insecticide composition comprises effective components and auxiliary components, wherein the effective components are imidaclothiz and lufenuron; the weight ratio of the imidaclothiz to the lufenuron is 1:(0.1-10); the weight percentage of the effective components imidaclothiz and lufenuron in the agricultural insecticide composition is 1-80%; the auxiliary components comprise a carrier and aids; the carrier is one or more of water, a solvent or packing; the aids comprise 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...
