Problems solved by technology

[0006] Since the 1980s, the research on botanical insecticides has been relatively in-depth, but the research on botanical fungicides has been relatively slow, and it is mainly in the stage of laboratory research and has not been applied in production.
[0010] However, these studies did not involve the use of "ethanol extracts of Sophora japonica and Niuxinpuzi" as fungic

Abstract

The invention discloses botanical fungicide for preventing and treating wheat scab. The botanical fungicide is prepared from components of sophora alopecuroide powder ethanol extract and cynanchum komarovii powder ethanol extract, smashing fineness of the extracts is 80 meshes, the sophora alopecuroide powder and the cynanchum komarovii powder are matched according to parts by weight of (1 to 9) : (9 to 1), the sophora alopecuroide powder and the cynanchum komarovii powder are evenly stirred, extracted twice through an ethanol solution with a mass concentration of 95% and mixed to obtain the botanical fungicide. The botanical fungicide for preventing and treating wheat scab disclosed by the invention is applied to wheat leaves at a wheat rupturing period and a wheat flowering period to kill wheat scab germs, inhibit scab expansion and reduce occurrence and harm of wheat scab.

Description

technical field [0001] The invention relates to a fungicide, in particular to a botanical fungicide for preventing and treating wheat scab. Background technique [0002] Fusarium scab is one of the main diseases threatening wheat production, and it occurs all over the world. The main pathogens of wheat head blight mainly include Fusarium graminearum Schw. and Fusarium culmorum Sacc. (Champeil A, Doré T, Fourbet J F. Fusarium head blight.epidemiological origin of the effects of cultural practice on head blight attacks and the production of mycotoxins by Fusarium in wheat grains [J]. Plant Science, 2004, 166: 1389-1415.). my country is the most harmful country of wheat scab in the world, with an annual damage area of ​​about 7.5 million hm2, accounting for 1 / 4 of the country's wheat area, resulting in a loss of 2-3 million tons of output (Simpson D R, Weston G E, Turner J A, et al al. Differential control of head blight pathogens of wheatby fungicides and consequences for myc...
