Embodiment approach

[0028] A simple dosage form is implemented as follows:

[0029] In the following embodiments, the components fluorourea and fenpropathrin are active ingredients.

[0030] One, preparation embodiment

[0031] 1. Wettable powder

[0032] Preparation method: According to the proportion of the formula in the example, add the active ingredients fluorourea and fenpropathrin into the carrier, and add surfactants and other functional additives to it, mix them, and mix them after jet crushing to obtain wettability powder. The main equipment is a mixer and a jet mill.

Embodiment 1

[0033] Example 1: (60% fluoride fenpropathrin wettable powder) 1:2

[0034] Formulation: fluorourea, 20%; fenpropathrin, 40%; wetting agent sodium lauryl sulfate, 2%; dispersant agent calcium lignosulfonate, 8%; filler silica, 18%, filler Kaolin, balance.

[0035] 2. Water dispersible granules

[0036] Preparation method: according to the proportion of the formula in the example, add the active ingredients fluorourea and fenpropathrin into the carrier, and add surfactants and other functional additives, mix, and add 10-25% of Water, then kneading, granulating, drying, and sieving to obtain water-dispersible granules; or spray the pulverized powder with water in a boiling granulator, granulate, dry, and then sieve to obtain the product. The main equipments are mixer, jet mill, kneader, extrusion granulator, drying room or fluidized bed drying, or boiling granulator, screening machine.

Embodiment 2

[0037] Example 2: (40% fluoride fenpropathrin water dispersible granules) 1:3

[0038] Formula: fluorourea, 10%; fenpropathrin, 30%; dispersant sodium alkylnaphthalene sulfonate, 5%, dispersant sodium lignosulfonate, 7%; wetting agent sodium lauryl sulfate, 2 %; urea (disintegrant) 5%, light calcium carbonate supplement, the balance.

[0039] 3. Suspending agent

[0040] Preparation method: according to the formula ratio, put the active ingredients fluorourea, fenpropathrin, surfactant and other functional additives in the reaction kettle in sequence, add water and mix evenly, undergo high-speed shearing, wet sanding, and finally The product is obtained by homogeneous filtration. The main equipment is batching kettle, colloid mill or homogeneous mixer, sand mill.

Abstract

The invention relates to an insecticidal composition in the field of combination of pesticides. Effective components of the insecticidal composition comprise novaluron and fenpropathrin, wherein the weight ratio of novaluron to fenpropathrin is (1 to 80) to (80 to 1), preferably (1 to 50) to (50 to 1); the total percentage by mass of the effective components in the insecticidal composition is 1%-90%, preferably 5%-60%; the rest components of the insecticidal composition are auxiliary components which are allowed to be used and are accepted in pesticides; a known method is capable of preparingthe insecticidal composition into wettable powder, dispersible oil suspensions, suspension emulsions, water suspensions, missible oil, water emulsions, micro emulsions or water dispersible granules. The insecticidal composition is mainly used for prevention and treatment of insect pests on tea trees and insect pests on vegetables and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition which uses fluorourea and fenpropathrin as active ingredients for binary compounding. Background technique [0002] Fluoxylurea novaluron, also known as diflufenuron, is one of the most active benzoylurea insecticides. It is mainly developed by Isagro S.p.A. in Italy. Fluoxylurea is a new type of insecticide containing Fluorine insect growth regulator can prevent chitin synthesis in the molting stage of insect growth. Lepidoptera (O type) affects insect molting, so that pests cannot form new epidermis during molting, and the insect body is deformed and dies. For some pests, it can also regulate the growth and development of insects, inhibit molt metamorphosis, and inhibit the feeding speed of pests, and has high ovicidal activity. At low doses, it shows high activity against pests such as Lepidoptera (spodoptera litura, diamondback moth,...
