Embodiment 1

[0044] Formula and preparation process of 30% lufenuron ultra-low volume liquid

[0045] Lufenuron 30kg, fatty alcohol polyoxyethylene ether 4kg, calcium dodecylbenzenesulfonate 3kg, N-methylpyrrolidone 20kg, dimethyl sulfoxide 15kg, methyl oleate supplemented to 100kg.

[0046] Preparation process: In a reaction vessel with electric stirring, first use a solvent to dissolve the active ingredient lufenuron according to the formula ratio, then add the auxiliary ingredients, stir and mix evenly, and then obtain 30% lufenuron ultra-low volume liquid agent; the process parameters are: the stirring speed is controlled at 60-150 rpm, the stirring time is 15-60 minutes, and the temperature is normal temperature.

[0047] According to the same preparation process as in Example 1, the following examples were prepared.

Embodiment 2

[0049] 12% lufenuron ultra-low volume liquid formulation

[0050] Lufenuron 12kg, fatty alcohol polyoxyethylene ether 3kg, calcium dodecylbenzenesulfonate 2kg, N-methylpyrrolidone 15kg, dimethyl sulfoxide 10kg, methyl oleate to make up to 100kg.

Embodiment 3

[0052] 4% lufenuron ultra-low volume liquid formulation

[0053] Lufenuron 4kg, fatty alcohol polyoxyethylene ether 3kg, calcium dodecylbenzenesulfonate 2kg, N-methylpyrrolidone 15kg, dimethyl sulfoxide 10kg, methyl oleate to make up to 100kg.

Abstract

The invention relates to the field of pesticides, in particular to ultralow volume liquid containing benzoylurea insecticide, which comprises active ingredients, solvent and adjuvant. The active ingredient I is optional one of lufenuron, diflubenzuron, triflumuron, chlorfluazuron and chlorbenzuron belonging to benzoylurea, and the active ingredient II is insecticide of another type of function mechanism. The ultralow volume liquid containing benzoylurea insecticide has the advantages of simplicity in processing, high efficiency, water saving, long-term effect, a target being not easy to resist the insecticide, low environmental pollution, synergy and the like. Application of ultralow volume spray, low volume spray or ultralow volume static spray is well effective in controlling ostrinia furnacalis, sugarcane borer, locust, peach fruit borer, lesser green leaf hopper, striped flea beetle, bean fly, diamond back moth, prodenia litura, cabbage caterpillar, leaf beetle, thrip, leaf miner, inchworm, red spider and the like, and the ultralow volume liquid containing benzoylurea insecticide can be used for effectively controlling various pests on wheat, maize, vegetables, tobacco plants, tea plants, fruit trees, cotton plants, woods and sugarcanes.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an ultra-low volume liquid containing benzoylureas. Background technique [0002] Benzoylurea insecticides as active components are a class of insecticides containing benzoylurea structure, including lufenuron, diflubenzuron, triflubenzuron, chlorfluazuron, diflubenzuron, fluoride Flubenzuron, pyridoxuron, flubenzuron, flunuron, polyflubenzuron, diflubenzuron, etc., mainly work through stomach poisoning and contact killing. This type of insecticide has a similar mechanism of action, mainly inhibiting the synthesis of chitin, hindering the normal peeling of insects, causing eggs to hatch, larvae to peel off, and pupae to develop abnormally, adult eclosion is blocked, the drug effect is high, and the speed of action is slow. A variety of Lepidoptera pests and Orthoptera, Coleoptera, Hymenoptera, Diptera, etc. have high activity. Benzoylurea insecticides have low toxicity and are harmles...
