Botanical fungicide for smut disease

Abstract

The invention discloses a botanical fungicide for smut disease. The fungicide comprises the following components in parts by weight: 20-30 parts of an ambrette extract, 15-25 parts of an abelmoschus esculentus extract, 10-20 parts of an avocado extract, 25-35 parts of a marasmius androsaceus extract, 30-40 parts of a mongolian dandelion herb extract, 20-30 parts of durian powder, 15-25 parts of a mesona fermented concentrate, 5-15 parts of malt and 10-20 parts of radix paeoniae rubra. Through the adoption of the manner, the botanical fungicide can effectively prevent and treat smut disease, can effectively reduce pesticide residue, and is free of damage to human health.

Description

technical field [0001] The invention relates to the field of fungicides, in particular to a botanical fungicide for smut. Background technique [0002] Sorghum head smut: The diseased plant is generally shorter and darker in color. Before heading, the lower part of the ear of the diseased plant is relatively swollen, the bracts are compact, and some ears are slightly tilted to one side, the bracts are peeled off, and the ear part becomes white The stick, this is "Umi". There is a layer of white membrane on the outside of the diseased ear. After heading, the outer membrane ruptures and a large amount of black powder is emitted, which is the teliospore. After the diseased ear sheds teliospores, there is a bunch of black filaments in it, that is, the residual fibrous vascular tissue. Some of the diseased ear is only partially exposed at the top or one side, but there are also all black ears exposed. When the leaves are infected, reddish-brown stripe spots are formed on the le...

Problems solved by technology

Due to the repeated use of large amounts of pesticides for the prevention and treatment of smut, the amount of pesticide residues has also increased, which is harmful to people's health
