Abstract
lPurple blotch and anthracnose disease are the main diseases of shallots. The purpose of this study was to obtain an environmentally friendly technology for controlling purple spot and anthracnose on shallots during the rainy season. The design used in this study was a split plot design with the main plots of shallot varieties (A) namely Sembrani, Bima Brebes and Maja Cipanas. As a sub-plot is the use of fungicides, namely chemical fungicides, chemical fungicides and biofungicides are used interchangeably and biofungicides are used routinely. The results showed that the Sembrani variety had a significant effect on reducing the severity of purple blotch, anthracnose, and stemphylium disease compared to the Bima Brebes and Maja Cipanas varieties. The use of chemical fungicides continuously is comparable to the use of chemical fungicides and biofungicides which are carried out alternately in suppressing the severity of purple blotch, anthracnose and stemphyllium diseases on shallots in the rainy season. Control by using chemical fungicides and biofungicides that are carried out alternately can save the use of chemical fungicides by 50%
