Southwest Michigan vegetable regional report – June 26, 2013

Vegetable crops have responded favorably to warmer temperatures and increased moisture.


According to Michigan State University Extension, temperatures for the week at the Southwest Michigan Research and Extension Center averaged above normal with highs from 75 to 88 degrees Fahrenheit (average is 77) and lows from 49 to 66 F (average is 56). We are at 917 base 50 GDD, which is slightly ahead of normal, but much behind the 1,184 of 2012. The area received an inch or more of rainfall during the period.

Field activity

Planting, harvesting and other activities continue with no problems. Plants have responded favorably to increased temperatures and soil moisture.

Crop reports

Tomato transplanting will be done this week. Earlier planted fields continue to be staked, tied and pruned. Fruit is setting well in response to favorable temperatures. Peppers and eggplants are doing much better in response to warm temperatures. Pepper plants have 2-inch fruit.

Yellow squash, zucchini and cucumber harvest continues. Harvest volume has increased as more fields come into production. Watermelon and cantaloupe are runnering off the plastic.

Early planted sweet corn is 36 inches tall with tassels beginning to emerge. Plants look much better due to increased temperatures.

Early planted potatoes are in bloom. Few Colorado potato beetles have been observed.


I have received reports of herbicide drift damage. Vegetable growers with field crop neighbors should warn those neighbors about how sensitive vegetables are to certain herbicides and to have them take special care in timing the application of those herbicides.
