The investigation of biomaterials on preventing crop diseases~ Sapindus mukorossi extract

Date:2014-06-17

Supindus extracts were applied to prevent strawberry powdery mildew this year. Results showed that except from mid July to end of July, powdery mildew occurred on strawberry plants and powdery mildew morbidity rate of non-applied strawberry was over 80 % from February to mid April and mid October to December. All supindus extract treatments could suppress powdery mildew significantly in the early months of the year, but only 25X supindus extract set was able to suppress in the end of the year.
