Crop reports

According to research done in the MSU hoophouses at the Student Organic Farm and MSU Extension educator observations from the field, growers are preparing beds for planting beets, carrots, Swiss chard and kale in hoophouses for fall harvest. Some examples of blossom end rot on slicing tomatoes has been observed.

Pests being seen include moderate numbers of cucumber beetles, blister beetles on pepper (an occasional pest found on plants in the tomato family) and some Japanese beetle damage. There have been isolated squash vine borer in zucchini in the field and some onion maggot damage in harvested garlic.

Diseases including early blight on tomato and leaf spot on cucumbers. Growers in Genesee County are also watching for downy mildew on cucumbers and melons since it have been confirmed in the state and recent humid, wet weather has been conducive to disease development.
