Abstract

The invention relates to a plant protecting agent which is prepared from the following raw materials according to parts by weight: 40 to 60 parts of discarded tobacco leaves, 2 to 7 parts of liquorice, 5 to15 parts of rhizoma arisaematis, 2 to 15 parts of rhizoma gastrodiae, 5 to 15 parts of dangshen, 2 to 7 parts of radix sophorae flavescentis, 2 to 7 parts of cortex phellodendri, 1 to 3 parts of aloe, 2 to 7 parts of asiatic moonseed rhizome, 2 to 9 parts of fructus xanthii, 0.5 to 1 parts of mountain seed oil, 0.1 to 3 parts of surfactants and 2 to 10 parts of thickening agents. A preparation method comprises the following steps: decocting the discarded tobacco leaves, the liquorice, the rhizoma arisaematis, the rhizoma gastrodiae, the dangshen, the radix sophorae flavescentis, the aloe, the asiatic moonseed rhizome and the fructus xanthii by adding water with quantity of eight times and six times and extracting for two times (two hours each time); filtering and combining the medicine liquid; concentrating the medicine liquid to have the relative density of 1.15 to 1.25; adding alcohol to enable the alcohol concentration to reach 60%; precipitating the filtered liquid to obtain a supernatant; carrying out spin steaming to remove the alcohol; and fully mixing the mixture by adding the surfactants, the mountain seed oil and the thickening agents, and emulsifying to be an uniform solution, thereby obtaining the plant protecting agent. The plant protecting agent is prepared from the pure traditional Chinese medicines, thereby being environment-friendly and free of pollution. In addition, the plant protecting agent has the advantages of abundant raw material sources, simplicity in preparation and low cost. Therefore, the plant protecting agent is suitable for industrialized mass production.

Description

technical field [0001] The invention relates to a plant protection agent and belongs to the technical field of pesticides. Background technique [0002] With the continuous improvement of people's quality of life, the requirements for food safety are also getting higher and higher. However, plant diseases and insect pests are bound to occur during the growth of plants, and pesticides will be used. These pesticides are generally chemical pesticides, which are highly toxic and powerful. It is not easy to decompose, and it will remain on the plants while killing the pests and diseases, seriously endangering the health of the eaters. How to invent a green, non-polluting, non-hazardous pesticide to replace chemical pesticides, so as to produce green and pollution-free organic food, has become an urgent problem to be solved. The use of natural insecticidal plants to develop highly efficient, non-toxic, and non-polluting botanical insecticides is gradually being highly valued by ...
