Abstract

The invention discloses plant-derived pesticide and a production method thereof. The plant-derived pesticide is prepared from Chinese herbal medicines such as licorice root, phellodendron bark, melia azedarach, cockscomb, radix ranunculi ternati, silktree flower, butterflybush flower, salvia chinensis, fenugreek seed and golden larch bark. A field test proves that the plant-derived pesticide has tobacco black shank prevention and treatment efficiency of 80% or more and has obvious effects better than that of metalaxyl with a concentration of 25%. The plant-derived pesticide has substantial prevention and treatment effects on a plurality of fungous diseases such as downy mildew, sclerotinia rot, powdery mildew, botrytis, anthracnose, epidemic disease, black shank and sheath blight of crops such as fruits, vegetables and paddy rice.

Description

technical field [0001] The invention relates to a pesticide and a production method, in particular to a botanical pesticide and a production method. Background technique [0002] At present, in the prevention and control of diseases such as fruits and vegetables, chemical agents are mostly used for prevention and control. The use of chemical pesticides undoubtedly makes various harmful bacteria resistant to drugs, which increases the difficulty of prevention and control. At the same time, it also causes harm to the plants themselves, and, There are residues in vegetables and fruits, endangering people's health, polluting the environment, and destroying ecological balance. As an important part of biopesticides, botanical pesticides have the advantages of high efficiency, low or no toxicity, low residue, and high selectivity, and have received more and more attention. With the development of botanical pesticides, Chinese herbal pesticides have gradually become the focus of re...
