Problems solved by technology

[0003] Although thiamethoxam EC has the advantages of simple manufacture, easy measurement, relatively uniform distribution of active components on target crops, and relatively high biological activity, the disadvantage is that a large amount of organic solvents, such as xylene and toluene, are used in the preparation process. Generally 20-90%, these solvents are highly toxic, flammable, unsafe for storage and transportation, prone to phytotoxicity to plants, and serious environmental pollution.
At the same time, these organic solvents will cause harm to the human body during the processing, packaging and use of emulsifiable concentrate. Especially during the spraying process of pesticide use, organic solvents are spilled into the natural environment, which not only causes serious pollution to the environment, but also causes biological chronic disease. poisoned

Embodiment 1

[0022] Embodiment 1: preparation concentration is 0.1% thiamethoxam insecticide

[0023] Described insecticide is made up of following components by mass fraction:

[0024] Thiamethoxam 0.1%

[0025] Pepper Essential Oil Head and Tail 95.0%

[0026] Emulsifier Hydroxymethylcellulose Starch 4.9%

[0027] Add thiamethoxam and emulsifier in sequence to the container containing pepper essential oil, put it into an ultrasonic oscillator and vibrate ultrasonically for 30 minutes, take it out and let it stand for 2 hours without any sediment to produce a shielding insecticide. In the present invention, the sprayer is directly mixed with water and sprayed on the farmland system, or the drone is used for spraying treatment. When spraying, it is not advisable to spray under strong sunlight or rainy days, so as not to reduce the efficacy of the medicine.

[0028] The preparation method and application method of the following examples are the same as this example.

Embodiment 2

[0029] Embodiment 2: preparation concentration is 0.1% thiamethoxam insecticide

[0030] Described insecticide is made up of following components by mass fraction:

[0031] Thiamethoxam 0.1%

[0032] Pepper Essential Oil Head and Tail 90.0%

[0033] Emulsifier Xanthan Gum 9.9%

Embodiment 3

[0034] Embodiment 3: preparation concentration is 0.1% thiamethoxam insecticide

[0035] Described insecticide is made up of following components by mass fraction:

[0036] Thiamethoxam 0.1%

[0037] Pepper Essential Oil Head and Tail 95.0%

[0038] Emulsifier calcium dodecylbenzenesulfonate 4.9%

Abstract

The invention provides a shielding protection insecticide capable of repelling natural enemy insects and bees. The shielding protection insecticide comprises the following components in percentage by mass: 0.1-40% of thiamethoxam, 50-95% of pepper essential oil and 1-10% of an emulgator. According to the product, primary oil and tail oil of plant essential oil are used for replacing toxic organic solvents used in a preparation process of missible oil; a pesticide barriering system of essential oil is formed; the effects of repelling, shielding and protecting natural enemy insects and bees can be achieved; the pesticide cost is reduced; the shielding protection insecticide has high insecticidal activity; the pesticide consumption is reduced; the shielding protection insecticide has significant technical effects.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a shielding and protective insecticide capable of repelling natural enemy insects and bees. Background technique [0002] Thiamethoxam is a high-efficiency neonicotinoid insecticide, which has contact killing, stomach poisoning and systemic activity, and has higher activity, better safety, wider insecticidal spectrum, fast action speed and long-lasting effect It is a better variety to replace organophosphorus, carbamate, and organochlorine insecticides that are highly toxic to mammals, have residues, and have environmental problems. It has high activity against Coleoptera, Diptera, Lepidoptera, especially Homoptera pests, and can effectively control various aphids, leafhoppers, planthoppers, whiteflies, scarab larvae, potato beetles, nematodes, ground beetles, Leaf miners and other pests. However, the excessive use of thiamethoxam has many hazards to the health of natural en...
