Combinations of basic copper sulfate (BCS) and maneb or mancozeb were significantly more effective for control of bacterial spot (Xanthomonas campestris pv. vesicatoria (Doidge) young et al.) of tomato than BCS by itself. Combinations of BCS with anilazene or captafol were no more effective than BCS alone. Copper-zine chromate was less efficacious than BCS when combined with maneb or mancozeb. BCS combined with maneb or mancozeb was less effective than meneb or mancozeb alone for control of late blight (Phytophthora infestans (Mont.) dBy.) and gray leaf spot (Stemphylium solani Weber) of tomato but was more effective than BCS alone.
