Problems solved by technology

Because most domestic products do not consider the absorption link, the drug efficacy is poor. Although some preparations have very good appearance indicators, the active ingredients are not well absorbed by the leaves.
Spirotetramat is generally toxic to adults, but it can affect its egg laying, even if it is produced, the eggs cannot develop normally

Embodiment 1

[0020] Weigh 5% spirotetramat, 50% mineral oil, 5% calcium dodecylbenzenesulfonate, 3% sorbitan monostearate polyoxyethylene ether, alkylphenol formaldehyde resin polyoxyethylene ether 3%, 1% lignosulfonate, 1% EO-PO block copolymer, 5% fumed silica, 3% organic bentonite, 15% dimethyl phthalate, and 100% corn oil. The above raw materials are mixed and ground with a sand mill until the particle size is less than 5 μm to prepare a 10% spirotetramat dispersible oil suspension.

Embodiment 2

[0022] Weigh 10% spirotetramat, 40% mineral oil, 4% calcium dodecylbenzenesulfonate, 5% castor oil polyoxyethylene ether, 2% alkylphenol formaldehyde resin polyoxyethylene ether, polycarboxylate 2%, fumed silica 3%, organic bentonite 2%, methyl oleate make up 100%. The above raw materials are mixed and ground with a sand mill until the particle size is less than 5 μm to prepare a 10% spirotetramat dispersible oil suspension.

Embodiment 3

[0024] Weigh 20% of spirotetramat, 30% of mineral oil, 6% of calcium dodecylbenzenesulfonate, 4% of phenylethylphenol polyoxyethylene polyoxypropylene ether, 1% of alkylphenol formaldehyde resin polyoxyethylene ether , EO-PO block copolymer 2%, magnesium aluminum silicate 2%, organic bentonite 3%, rapeseed oil make up 100%. The above raw materials are mixed and sanded with a sand mill until the particle size is less than 5 μm to prepare 20% spirotetramat dispersible oil suspension concentrate.

Abstract

The invention relates to an agricultural insecticide, in particular to spirotetramat dispersible oil suspension containing mineral oil, a preparation method of the suspension and an application of the suspension, and belongs to the field of chemical pesticide processing. The dispersible oil suspension comprises, in weight percentage, 5-50% of spirotetramat, 0.5-10% of thickening agents, 10-15% of emulsifying agents, 0.5-10% of dispersing agents, 5-50% of mineral oil and the balance dispersion media. The problem of difficulty in preparing the dispersible oil suspension by the spirotetramat is solved. Compared with common preparations such as wettable powder, water dispersible granules and water suspension, the spirotetramat dispersible oil suspension has the advantages of environmental protection, efficacy improvement, high crop safety, rain wash resistance and long lasting period and has excellent prevention and control effects on crop pests such as scale insects, aphids, wood louses and whiteflies.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to a spirotetramat dispersible oil suspension containing mineral oil and its preparation method and application, belonging to the field of chemical pesticide processing. Background technique [0002] Spirotetramat, English name Spirotetramat, chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5 ]-dec-3-en-2-one. High-efficiency broad-spectrum insecticide, used to control a variety of piercing-sucking mouthparts pests; systemic absorption, two-way conduction, can protect new tissues and roots; long-lasting, long-term protection of crops from pests; research shows that its Important beneficial insects such as ladybugs, hoverflies and parasitic wasps have good selectivity and are suitable for integrated pest management. Spirotetramat has unique action characteristics and is the only modern insecticide with two-way systemic conduction properties so far. The compou...
