The following is a brief report of the pest and non-infectious problems found on vegetable in Indiana over the past 10 days.
Tomato-In high tunnels and greenhouses, scattered growers have observed leaf mold, gray mold and white mold. Tomato spotted wilt has also been observed on tomatoes in high tunnels. Unfortunately, herbicide drift has also been reported on tomatoes in high tunnels.
Cucurbits-Most diseases reported on cantaloupe and watermelon have been those observed in transplant trays. These diseases include gummy stem blight and angular leaf spot. In the field, Fusarium wilt has been observed on watermelon. Hail damage has been observed on cantaloupe and watermelon in the field. Cucumber beetles have been observed on cucurbits. Drift damage has also been observed on cucurbit crops. Figure 1 shows an example of a contact herbicide on a watermelon leaf in contrast with gummy stem blight.

Figure 1. Contact herbicide damage on a watermelon leaf, on the left, causes a round, light colored lesion with little internal structure. The leaf with gummy stem blight, on the right, has expanded, dark lesions with clear ring-like structure.
Cabbage-Black rot has been observed on cabbage.
