Bravo 500EC and Difolatan 80W, either aloneorin combination with copper oxychloride, provided the best control of Corynespora leafspot of tomatoes in field plot trials with eight fungicides or combinations. Although not providing as effective a control, the use of Dithane 2–78 was the most cost effective based on yield per 100 m2or per kg of fruit in the first test. Disease intensity was significantly lower in plots sprayed with Bravo and Difolatan on a 3‐day schedule than on a 7‐day schedule through the first harvest in a second trial. Differences in disease intensity between treatments and the control were not significantly different at final harvest, which may indicate the importance of early season control. Yields from Bravo‐sprayed plots were significantly greater than yields from Difolatan‐sprayed plots, and yields from plots sprayed with either Bravo or Difolatan on 3‐ or 7‐day schedules were significantly greater than yields from unsprayed controls in this experiment. In a third experiment, disease Intensity was significantly lower in plots sprayed with Bravo or Difolatan, or with these fungicides applied in combination with copper oxychloride, than in the unsprayed control plots. The combinations with copper oxychloride were more effective than Bravo or Difolatan alone.
