Southeast Michigan Fruit Update Highlights Weather Pests and Crop Conditions

By Andi Anderson

The latest update for southeast Michigan fruit crops highlights changing weather conditions and their impact on crop growth and management. Cool temperatures in the past week have slowed bloom progression in many fruit crops. Although frost risks were present, temperatures remained above damaging levels. The coming days are expected to remain cool, dry, and windy, with some scattered rain later in the week.

Weather conditions are affecting farming practices, especially spraying activities, due to increased wind. Growers are advised to stay alert and adjust their management plans accordingly. Integrated pest management meetings are being conducted weekly to help farmers stay updated and receive expert advice.

Among fruit crops, apples are currently between full bloom and petal fall stages, while some late varieties are just starting to bloom. Blueberries are entering the bloom stage, which increases the risk of diseases like mummy berry and phomopsis. Protective fungicide applications may be necessary during this stage.

Cherries and plums are also progressing through bloom and petal fall stages. These phases are sensitive to temperature changes, making frost monitoring important. Grapes are showing early growth, including bud burst and leaf development. Peaches and nectarines vary by location, with some areas reaching petal fall and others at full bloom. Pears show varied bloom stages depending on farm conditions.

Strawberries are beginning to bloom and develop new leaves. Early-season disease management is important, particularly for leaf spot control.

Insect activity is increasing gradually. Early catches of pests, such as codling moth, green fruitworm, and oriental fruit moth, have been reported. These pests can damage crops if not controlled at the right time. Proper insecticide use after bloom can help manage infestations.

Disease risks such as apple scab, fire blight, brown rot, and powdery mildew are being closely monitored. Early control measures are important to prevent spread during the growing season.

Rainfall in the region has been slightly above normal, and growing degree days are ahead of average levels. This indicates faster crop development overall.

Farmers should carefully monitor crop stages, weather forecasts, and pest activity. Timely actions and proper planning will help maintain crop health, reduce losses, and ensure a productive growing season.
