| Abstract: | Abstract 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. |
