Abstract

The invention provides a preparation method of a biological disease and pest prevention medicine used for melon and fruit vegetables. The biological disease and pest prevention medicine is low in toxicity, residue and cost, has long acting time and is very suitable for the melon and fruit vegetables. The preparation method comprises the steps of: (A) preparation of main materials: the main materials include the following raw materials, by weight, 2-4 parts of chili, 3-6 parts of Chinese prickly ash, 5-8 parts of pyrethrum, 8-10 parts of tobacco, 6-9 parts of derris fordii and 2-3 parts of tea seed cake; (B) preparation of auxiliary material: the auxiliary material includes 0.5-0.8 parts of sophocarpidine; and (C) preparation of the medicine: adding 60-100 parts of water to the main materials for decoction, and performing filtration to obtain a primary filtrate, adding 40-80 parts of water to filter residue for decoction, and performing filtration to obtain a secondary filtrate, and mixing the two filtrates, decreasing the temperature, and adding water to dilute the filtrates to obtain 250-400 parts by weight of a mixture liquid, and adding the auxiliary material to the mixture liquid according to 1:500, and uniformly stirring the mixture liquid to obtain the medicine.

Description

technical field [0001] The invention relates to the technical field of biological pest control, in particular to a preparation method of a biological pest control agent for fruits and vegetables. Background technique [0002] Pesticides play a very important role in vegetable production. With the improvement of people's health awareness, China is a big agricultural country. Most countries attach great importance to the safety of agricultural products and vegetables, and the restrictions on pesticide residues are very strict. It is the future trend to reduce and eliminate the use of chemical pesticides and develop botanical pesticides. [0003] Botanical pesticides are derived from nature and can be degraded in nature. Generally, it will not pollute the environment and agricultural products. It is unlikely to accumulate toxicity in the environment and the human body. It is relatively safe for humans and livestock, and has little damage to natural enemies of pests. It is di...
