Ampholytic organic pesticide

Abstract

The invention discloses an ampholytic organic pesticide. The ampholytic organic pesticide is prepared from the following components by weight percent: 35-45% of bamboo vinegar or wood vinegar, 15-25% of tobacco stem extract, 5-8% of allicin oil, 3-5% of camphor oil, 5-8% of rotenone, 8-16% of pesticide emulsifier, 5-8% of orange peel extract and 5-10% of alcohol. The preparation method of the tobacco stem extract comprises the following steps: soaking tobacco stems with bamboo vinegar in a volume ratio of 1:1, boiling, distilling to obtain distillate, cooling the distillate and filtering to obtain filtrate, namely the tobacco stem extract. The preparation method of the orange peel extract comprises the following steps: mixing fresh orange peels and bamboo vinegar in a ratio of 1:1, adopting the water distillation method to distill and obtain distillate, namely the orange peel extract. The tobacco stem waste is utilized, thus the method is economical and environmentally-friendly. The preparation method of the ampholytic organic pesticide is simple, the used raw materials are available; and the method uses pollution-free materials and is harmless for human body and crop.

Description

technical field [0001] The invention belongs to a preparation method of an organic pesticide. Background technique [0002] At present, the pest control substances used are generally chemical pesticides. Although they are stable in nature and can kill certain pests, they are highly toxic and cause serious residual pollution. From July 1, 2000, the European Union implemented a new maximum pesticide residue limit standard for Chinese tea entering the EU market. In addition to more than a dozen quality standards and safety and health standards for Chinese tea imports, Russia also added a metal magnetic substance. , thus causing difficulties for my country's tea export. This requires strict competition and selection in the use of chemical pesticides, to find a repellent that can eliminate insects and is harmless to crops, and can be beneficial to crop growth. There are 300 million smokers in our country. In the process of burning tobacco, a large number of tobacco rods are disc...
