Southeast Michigan vegetable regional report - September 5, 2012
Vegetable crop harvest continues in the southeast, while cool weather gives relief to growers.
We had 1/10 of an inch of rain Monday, September 3 (in two rain events). Temperatures ranged from 48 to 94 degrees Fahrenheit. Most days, during the past week, were cloudy with some fog following rain events. Humidity has ranged from 30 to 94 percent, with three to 11 hours of wetness.
Crops and pests
Sweet corn harvest is wrapping up. Thirty-one corn earworm moths were caught in the Monroe County trap.
Tomato and pepper harvest continues. Aphids are present in eggplants. In most potato fields, potato vines have been killed and harvest is ongoing.
Cucumber, zucchini and squash harvest is complete for the most part; some muskmelon and cantaloupe harvest is ongoing. Pumpkin harvest has started and will continue.
Cucurbit downy mildew epidemic continues in Michigan; 13 counties have confirmed reports of cucurbit downy mildew. Spore counts dropped last week, but the cool weather and foggy mornings, like Tuesday (September 4), are conducive to disease. For pumpkins and melons that were planted later, it is important to protect the crops to avoid major losses. Follow MSU’s Mary Hausbeck’s spray recommendations for downy mildew.
