Control of bacterial speck of tomato by copper and ethylenebisdithiocarbamate fungicides: their efficacy and residues on leaves.
Field studies were conducted to determine the synergism, persistence, and efficacy of a tank-mix spray of cupric hydroxide and mancozeb for control of bacterial speck of tomato. The increased efficacy of the cupric hydroxide-mancozeb mixture could not be attributed to the formation of a bacteriostatic compound in the tank mixture nor to a greater persistence of the mixture on the tomato foliage.
