Biological pesticide (biogenic pesticides) refers to the direct use of biological metabolism process of bioactive substances or substances extracted from organisms are pesticides for controlling diseases and insect pests. Biogenic pesticides are processes that control and regulate the growth, development and reproduction of various harmful organisms. According to the use of biogenic insecticides, biogenic fungicides, biogenic herbicides and plant growth regulators are more used in organic agriculture. Herb ingredients for insecticide can be a safe and effective way to control insect pests in your garden and farm. Herb ingredients are very effective as insect repellents and can be used alone or in combination to boost insecticidal properties, some can be lethal to some insect eggs. Mature products in this market are pyrethrin, rotenone, azadirachtin, matrine, picotensin, veratrine, allicin, osmanthus, and sanguinarine, etc.
