Harvest of field-planted fresh market cucumbers, pickles, and summer squash started last week.

Michigan vegetable report | June 23, 2022
Aerial downy mildew spores were detected in Bay and Saginaw counties in mid-June. Growers were advised to start monitoring for downy mildew symptoms and to start using proven protectant fungicides before symptoms begin. Phytophthora fruit rot on pickles continues to be a major threat for some Michigan growers. Effective fungicides must be applied so that they cover the fruit. Fungicides applied to the soil are not effective and do not limit the pathogen. Also, fungicides applied to the foliage are not translocated to the fruit.
