- No tomato late blight has been confirmed yet this season, but we typically see an increase in tomato detections at the end of the production season if weather promotes the disease. Sunny days have and will continue to limit late blight.
- We’ve been seeing an increase in incidence and severity of downy mildew on cucumbers this season, in comparison to past recent years. Maintain protective fungicide applications on winter squash and pumpkins that require a longer time to maturation/harvest.
