Abstract

The invention provides a plant fungicide, which is prepared by using umbelliferone as main raw material and by the step of adding solvent, solubilizer and / or emulsifier in the umbelliferone. The plant fungicide is an environment-friendly acceptable pesticide, which is safe to animals and human beings, and has a profound significance for the long-term development of the ecological environment, the health of the human beings and the comprehensive treatment of the diseases. Compared with the traditional pesticide, the plant fungicide of the invention has the following characteristics and advantages: 1, the umbelliferone has a strong bactericidal activity and can become a good development resource; 2, because of the fat-soluble characteristic, the plant fungicide is safe to mammals and unlikely to cause pesticide phytotoxicity and toxicity residual, namely the plant fungicide is safe for the animals, human beings and ecological environment; 3, the plant fungicide can be artificially synthesized easily and therefore is quite helpful for industrialized production; and 4, when the pesticide is prepared by mixing other effective germicidal components in preparative plants, an effective bactericidal effect can be further increased.

Description

technical field [0001] The invention relates to a plant fungicide of umbelliferin and a new application of umbelliferin. Background technique [0002] Umbelliferone, also known as umbelliferone; 7-hydroxycoumarin, molecular formula: C 9 h 6 o 3 , Needle crystal, easily soluble in ethanol, chloroform, acetic acid; soluble in dilute alkali; slightly soluble in ether. It can produce coumarin odor when heated. Soluble in dilute alkalis, the solution is blue fluorescent. Umbelliferone exists in the root of carrot of umbelliferous plant, the seed of corolla variegata of leguminous plant, and the whole grass of Rutaceae plant Rutaceae. It has antibacterial, antihypertensive and anticancer effects. It can be used as an acid-base indicator and a fluorescent indicator for the determination of calcium and copper. However, there is no report on the application of umbelliferone in the preparation of plant fungicides in the existing literature, and it is imminent to develop a pollu...
