Botanical fungicide synergistic agent, extracting technique and application thereof in agricultural fungicide

Abstract

The invention discloses a botanical fungicide synergistic agent, an extracting technique and the application thereof in agricultural fungicide. The botanical synergistic agent is extract of pericarp of citrus fruit; the three-time extracting technique is adopted, and ultrasound-assisted extraction is applied, so that the maximum extraction capacity of active ingredient can be ensured; the technique is simple and seldom affects the environment, and the botanical fungicide synergistic agent can be taken as synergistic agent to be matched with the traditional chemical bactericide for use, so that the sterilizing effect is remarkably improved; the botanical fungicide synergistic agent can be added into liquid preparation and solid preparation, and more particularly can be applied to preparations such as microemulsion, suspending agent, wetting powder, water dispersible granules, etc.

Description

technical field [0001] The invention relates to the technical field of agricultural fungicide preparations, in particular to a botanical fungicide synergist, its extraction process and the application of the extract as a synergist in agricultural fungicide preparation technology. Background technique [0002] Citrus is the general name of tangerine, tangerine, orange, kumquat, pomelo, and trifoliate. It has been cultivated in my country for more than 4,000 years, and many strains have been formed. The citrus fruit has both excellent color and fragrance, rich juice, and beautiful flavor. In addition to sugar, organic acids, and minerals, it is also rich in vitamin C and a variety of glycosides, with high nutritional value, so it is often used as Chinese medicinal materials and health food. It is reported that citrus is beneficial to Qi, strengthens the body, aids digestion, It has the functions of invigorating the spleen and stomach, lowering blood pressure, etc., and has certa...

Problems solved by technology

[0003] The extract product of citrus appears on the market at present, but it is various health medicines, similarly, although there are data records for the extraction process of citrus peel, as mentioned the process research of extracting pectin from orange peel by microwave method, and Orange peel is used as raw material. Under microwave conditions, the pH value of the extract is adjusted with mixed acid, and the pectin is extracted by anhydrous ethanol precipitation process. However, the extract of orange peel is used as a bactericidal synergist in agriculture and its extraction process and Applications in pesticides have not been reported

[0004] In the process of prevention and control of agricultural diseases, chemical fungicides are mainly used to deal with them. Although the sterilization speed is fast and the effect is obvious, with the long-term and unreasonable use of various chemicals, the bacteria have developed serious drug resistance, and the drug effect has gradually decreased. The harm to the environment is also becoming more and more serious. Therefore, the search for botanical fungicides with good environmental compatibility has become the current mainstream direction
