Weather and insect activity

Wet weather continued to occur in southeast Michigan during the past week. Total rainfall amount for the period was 1.25 inches, and fields have remained wet and difficult to work in. Daytime temperatures ranged from 60°F to 76.5°F, and night time temperatures varied from 42.4°F to 50°F. Fortunately, no frost has occurred in the past week.

Insects have been active on the sunny days we have had, but no reports of feeding injuries on vegetable crops is being reported. Generally, the cool, wet weather has inhibited insect activity.

Crop report

Very little has changed in the past week regarding crop planting. Fields have been too wet in most places for growers to be able to get in. Sweet corn that has been planted has emerged, but is growing slowly. Some sweet corn fields that experienced frost damage during the last frost events have been slow to recover. Some cucumbers under low plastic tunnels are growing well. Cabbage transplants appear to be also growing well with no significant insect or disease problems.
