Description

technical field [0001] The invention relates to a pollution-free pesticide, in particular to a pollution-free pesticide prepared from natural plants as raw materials. Background technique [0002] At present, in the field of pesticide use, organic pesticides and inorganic pesticides are still the main ones. Long-term use of such pesticides will cause many disadvantages. Therefore, such pesticides are likely to cause adaptability and resistance to the pests, resulting in a decrease in the efficacy of the pesticides. In order to increase the insecticidal effect, farmers usually kill the pests by increasing the amount of pesticide application or using excessively large concentrations of pesticides. If things go on like this, pesticide residues will exceed the standard, destroying the ecological environment, reducing the number of many precious organisms and rare animals and plants, and reducing the output of wild species such as wild grass Ganoderma lucidum, fungus Ganoderma l...
