Plant sterilizing agent and preparation method thereof

Abstract

The invention provides a plant sterilizing agent which is prepared from the following raw materials of traditional Chinese medicines by weight: 50 to 150 parts of solanum nigrum, 150 to 350 parts of rThe invention provides a plant sterilizing agent which is prepared from the following raw materials of traditional Chinese medicines by weight: 50 to 150 parts of solanum nigrum, 150 to 350 parts of radix euphorbiae ebractealatae, 50 to 150 parts of stoneseed and 50 to 150 parts of red paeonia. In the preparation, the raw materials with the parts by weight are taken according to the proportion, thadix euphorbiae ebractealatae, 50 to 150 parts of stoneseed and 50 to 150 parts of red paeonia. In the preparation, the raw materials with the parts by weight are taken according to the proportion, the water weighing 5 to 10 times as the total weight of the raw materials is added to be decocted for 0.5 to 2.5 hours, and the slag is removed by filtration to obtain the plant sterilizing agent. The re water weighing 5 to 10 times as the total weight of the raw materials is added to be decocted for 0.5 to 2.5 hours, and the slag is removed by filtration to obtain the plant sterilizing agent. The raw materials of the sterilizing agent are the raw materials of traditional Chinese medicines, no residue is left after the sterilizing agent is used, and the sterilizing agent has no pollution and damaw materials of the sterilizing agent are the raw materials of traditional Chinese medicines, no residue is left after the sterilizing agent is used, and the sterilizing agent has no pollution and damage on the environment, is in accordance with the strategy of continuous development and has a good developing prospect. The sterilizing agent has simple and feasible preparation technology and easy aage on the environment, is in accordance with the strategy of continuous development and has a good developing prospect. The sterilizing agent has simple and feasible preparation technology and easy application, makes a good contribution for lowering the pesticide price, can be prepared by peasants to save expenditure, and enables the peasants to be directly benefited.pplication, makes a good contribution for lowering the pesticide price, can be prepared by peasants to save expenditure, and enables the peasants to be directly benefited.

Description

technical field [0001] The invention relates to a fungicide, in particular to a plant fungicide prepared from traditional Chinese medicine raw materials, and also relates to a preparation method of the plant fungicide. Background technique [0002] In agricultural production, major diseases of fruit trees, vegetables and food crops will seriously affect the normal growth of these crops, thereby affecting the improvement of crop quality and yield. If they cannot be controlled and treated in time, they will also lead to the spread of diseases. For example, powdery mildew, rot, green onion black spot, grape gray mold, black pox, downy mildew, white rot, anthracnose, etc. are all common diseases of crops. These diseases are all diseases caused by pathogens. These diseases The incidence area is wide and the damage is serious. In order to prevent and control diseases, chemical pesticides and fungicides are used in production for prevention and control, such as fenxining, carbenda...

AI Technical Summary

Problems solved by technology

In order to prevent and control diseases, chemical pesticides and fungicides are used in production for prevention and control, such as fenxining, carbendazim, streptomycin, and thiophanate-methyl, mancozeb, chlorothalonil, DuPont Yibao and other bactericidal chemical preparations , but there are many disadvantages in the use of chemical pesticides. For example, pesticides are easy to remain on crops. Eating them will cause harm to humans and animals, and it will easily cause chronic poisoning. It will also cause harm to the food chain and pollute the environment; When multiple diseases occur at the same time, they cannot be controlled at the same time, and many chemical pesticides cannot be used in combination at the same time, and long-term use or improper application methods will cause the bacteria to develop strong resistance to the above-mentioned agents; moreover, the price of pesticides is high.
