Abstract

The invention provides an herbal pesticide and a preparation method thereof. The preparation method is characterized by comprising crushing stropanthus divericatus, graceful jesamine, flaccid knotweed herb, encalyptus robusta, camphorwood leaf, melia azedarach leaf, wikstroemia indica, derris root, tobacco, ailanthus altissima leaf, Chinese tallow tree leaf, pod pepper, sessile stemona root, ilex rotunda, lantana camara, peach leaf, lemon leaf and datura, adding the crushed materials into water of which the weight is 5-10 times total weight of the crushed materials, carrying out reflux stewing at a temperature of 80 to 100 DEG C for 30 to 90min, and filtering to the herbal pesticide. The herbal pesticide has a wide insecticidal spectrum, low toxicity and no damage on human and animals, can be biodegraded completely, does not produce residues, guarantees agricultural product safety, and is suitable for production of organic agricultural products.

Description

technical field [0001] The invention relates to a herbal pesticide and a preparation method thereof, belonging to the field of biological pesticides. Background technique [0002] In the process of agricultural production, in order to prevent crops from being harmed by pests and fungi, ensure the healthy growth of crops, and achieve the purpose of increasing production, pesticides are used. The use of a large number of pesticides has achieved the protection of crops, guaranteed production, and solved the role of the world food crisis. However, most pesticides are highly toxic and harmful to humans and animals. The large amount of pesticide residues in food reduces the safety of agricultural products. At present, the vast majority of pesticides on the market are produced by chemical synthesis. The wastewater, waste gas, and waste residues discharged during the pesticide production process are very toxic. Direct discharge will inevitably cause great damage to the environment a...
