A plant-sourced fungicide used for sclerotiniose

Abstract

A plant-sourced fungicide used for sclerotiniose is disclosed. The fungicide comprises 7-18 parts by weight of a lotus leaf extract, 20-30 parts by weight of herb of bastardtoadflax-like swallowwort, 15-25 parts by weight of a compound named as a Chinese character 'Nezha' by the inventor, 10-20 parts by weight of sugar pear, 8-19 parts by weight of a black fungus extract, 25-35 parts by weight of a chaga mushroom extract, 5-15 parts by weight of pinitol, 10-20 parts by weight of turmeric root tuber, 5-15 parts by weight of giant knotweed rhizome and 20-30 parts by weight of rhino horn. By the manner, the fungicide can effectively control the sclerotiniose, pesticide residues are reduced, and environment pollution is avoided.

Description

technical field [0001] The invention relates to the field of fungicides, in particular to a botanical fungicide for sclerotinia. Background technique [0002] Sclerotinia is a common disease of tomato, which occurs in some protected areas of old vegetable areas. Generally, the disease occurs sporadically, causing plant necrosis. The disease of tomato is relatively serious, and it often causes rotten fruit. Once it occurs, it will have a significant impact on the yield. Mainly affects stems and fruits. The stem is infected with water-soaked dark green to off-white soft rot, and flocculent white mold is produced on the diseased part, which later turns into rat feces-like sclerotia. Growing plants wilt and die. When the fruit is infected with the disease, it is dark green and water-soaked soft rot. Dense flocculent mycelium grows on the disease, and turns into black sclerotia in the later stage. As the disease progresses, the diseased fruit rots and falls off. In addition, ...

Problems solved by technology

In addition, the amount of pesticide residues in grains has also increased due to the repeated use of large amounts of pesticides for the prevention and treatment of Sclerotinia.
