Abstract

A field study was conducted to determine the potential use of Effective Microorganisms (EM) for control of Xanthomonas campestris pv vesicatoria, a bacterial pathogen of sweet pepper (Capsicum annum cv margareth). Sweet pepper seedlings were transplanted into field plots where soil had been treated with EM, a biofertilizer (Vairo), or left untreated as controls. After 60 days, a suspension of 10⁸ CFU ml^-1 of Xanthomonas campestris pv vesicatoria was sprayed over the plants. Disease incidence and the number of bacteria were evaluated. The results indicate that both EM and Vairo (a biofertilizer product derived from anaerobic fermentation of cow manure) may have potential for the control of Xanthomonas campestris pv vesicatoria in sweet pepper.
