A barrier-protective insecticide against natural enemies insects and bees

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 pesticide capable of repelling natural enemy insects and bees. Background technique [0002] Thiamethoxam is a nicotinic high-efficiency 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 those organophosphorus, carbamate and organochlorine pesticides with high toxicity to mammals, residues and environmental problems. It has high activity to 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 overuse of thiamethoxam has many hazards to the health of natural enemy insects and bees, and...

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
