Low-toxicity type environment-friendly pesticide

Abstract

The invention discloses a low-toxicity type environment-friendly pesticide which is prepared by the following raw materials of, by weight, 1-2.3 parts of an emulsifier, 5-10 parts of oxyfluorfen, 4-6.7 parts of carboxymethyl starch, 3.5-5.5 parts of food colouring phloxine, 3-5 parts of nicotine extract, 4-7.5 parts of sulfur powder and 18-21 parts of water. The pesticide has the characteristics of low toxicity, almost no residues, safety to human and animals, no harm to plants, without pesticide resistance to insect pests, and the like. The pesticide has contact poisoning and stomach poisoning functions to a plurality of insect pests, without internal absorption or fumigant effects. The pesticide is low in cost and simple in process, and generates no public nuisance during the preparation process. The raw materials are easy to collect. The pesticide is helpful to the utilization of wastes of tobacco leaves of a cigarette factory, and can alleviate environment pollutions. The extracted raw material residues can be used as a fertilizer or developed into forage.

Description

[0001] technical field [0002] The invention relates to a pesticide, in particular to a low-toxic environment-friendly pesticide, which belongs to the field of chemicals. Background technique [0003] With the improvement of people's living standards, higher requirements are put forward for food safety, high quality and environmental protection, and the demand for green food is increasing; in international trade, the amount of pesticide residues has also become an international food and Green barriers to trade in agricultural products. At present, more than 80% of the pesticides used in our country are artificially synthesized chemical reagents. Chemical pesticides are highly toxic and difficult to degrade, and the damage to the ecological environment caused by large-scale use has attracted more and more attention. Plant pesticides are a new type of pesticides that can prevent and control plant diseases and insect pests, which are made from plants and plant extracts. It ...
