Embodiment 1

[0024] Example 1 (-)-Determination of bactericidal activity of isogemaphenol

[0025] The (-)-isogray phenol sample extracted from the seeds of amorpha pseudoacacia was used to test the activity of protecting plants against fungal diseases in vivo. The test methods for the protective effect of controlling cucumber downy mildew are as follows:

[0026] Choose a potted cucumber seedling that grows uniformly, cut off the growth points and retain two true leaves as test materials. Foliar spray treatment with extract (-)-isogray stigmasol according to the designed concentration, and a blank control of spraying clean water, repeated 3 times. After treatment, the cucumber downy mildew sporangia suspension was inoculated on the second day, and then placed in an artificial climate room (temperature: day 25 ℃, night 20 ℃, relative humidity: 95-100%) moisturizing culture, 24 hours later placed in the greenhouse ( 25+2℃) and manage normally, and investigate the control effect after 5 days. ...

Abstract

The invention first separates amorpha fruticosa seeds to obtain (-)-sumatrol with agricultural fungicide activity and discloses (-)-sumatrol having strong restrain and disinfection functions on phytopathogen. The (-)-sumatrol can be prepared into agricultural fungicide, widens using ranges of leguminous plant amorpha fruticosa and provides reliable technical base for development of plant pesticide.

Description

Technical field [0001] The invention belongs to the application field of pesticides, and relates to the comprehensive utilization of legume amorpha, and specifically relates to the use of an active substance (-)-isogresophenol obtained by separation and purification from amorpha seeds as an agricultural fungicide. Background technique [0002] Amorpha fruticosa L. is a deciduous cluster shrub belonging to Leguminosae (Leguminosae). There are about 25 species of Amorpha plants all over the world. They are native to North America, and there is only one Amorpha species introduced and cultivated in my country. Amorpha pseudoacacia is cultivated in the north and south of my country. It has strong applicability, wide distribution, and has good functions of windbreak, sand fixation, and water and soil conservation. It is mainly used for water and soil conservation in northern my country, especially in desert areas. In addition, it is cultivated for ornamental purposes and is also a nec...
