Problems solved by technology

[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 will inevitably 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 plants while killing diseases and insect pests, seriously endangering the health of consumers

Embodiment 1

[0019] The plant protection agent of this embodiment is made from the following raw materials: Rehmannia glutinosa 30kg, Eupatorium 4kg, Moutan cortex 12kg, Sophora flavescens 8kg, Latium chinensis 12kg, Goose Bubivora 5kg, Fructus cocklebur 5kg, Plantain 1.5kg kg, bamboo yellow 4kg, raw oyster 1.5kg.

[0020] The preparation method of the plant protection agent of the present embodiment may further comprise the steps:

[0021] Step 1. Mix the raw materials and add water to decoct and extract twice. The amount of water added for the first time is 10 times the total mass of the raw materials, and the decoction time is 2 hours. The amount of water added for the second time is 8 times the total mass of the raw materials. The cooking time is 2 hours. After filtration, the filtrate is combined and concentrated to 50°C to measure a thick paste with a relative density of 1.30;

[0022] Step 2: Add ethanol to the thick paste described in step 1 until the alcohol content is 60%, stir ...

Abstract

The invention discloses a plant protective agent prepared from the following raw material medicines in parts by weight: 20-40 parts of radix rehmanniae recen, 2-6 parts of herba lycopi, 6-17 parts of cortex moutan, 2-13 parts of radix sophorae flavescentis, 6-17 parts of sowthistle tasselflower herb, 2-8 parts of herba centipedae, 2-8 parts of fructus xanthii, 1-2 parts of plantain herb, 2-6 parts of shiraia bambusicola henn, and 1-2 parts of raw oysters. In addition, the invention also discloses a preparation method of the plant protective agent. The plant protective agent is prepared by adopting the pure traditional Chinese medicines, is green, has no pollution, and is rich in raw material sources, simple in preparation process, relatively low in cost, and suitable for agriculture industrialization production. The plant protective agent has relatively strong inhibitory activity against botrytis cinerea pers and pseudoperonospron cubensis, is a non-toxic grade, has a dosage form of a liquid agent, is safe to use, has no pollution to the environment and vegetables, and is the plant protective agent having a promotional value.

Description

technical field [0001] The invention belongs to the technical field of plant protection agents, and in particular relates to a plant protection agent and a preparation method thereof. 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 replace chemical pesticides with green, pollution-free and harmless pesticides, so as to produce green and pollution-free organic food, has become an urgent problem to be solved. Using natural plants to extract efficient, non-toxic, non-polluting plant protective agents is graduall...
