Southeast Michigan Fruit Update Highlights Crop Progress and Pest Risks

By Andi Anderson

The latest fruit update from southeast Michigan provides important information on crop growth, pest activity, and weather conditions. Recent weather has been wetter than usual, with variable temperatures.

In the coming days, cooler weather with possible rain and humidity is expected. These conditions may increase the risk of plant diseases while making it harder for farmers to apply sprays effectively.

Disease management is a key concern this week, especially for grapes. Growers are watching for powdery mildew and black rot, which can spread quickly in humid conditions. Farmers are advised to plan sprays carefully, as wind and rain could interrupt proper application.

Different fruit crops are at various growth stages across the region. Apples are growing in size, although some fruit may drop naturally. Blueberries are also developing well, with some beginning to change color in warmer areas. Strawberries continue to be harvested, and cooler weather may help extend the season in certain areas.

Cherries are beginning to ripen, with early varieties being picked. However, some farms have reported low production due to earlier frost conditions.

Grapes are mostly at the fruit set stage, and growers are encouraged to control black rot during this critical time. Peaches, nectarines, and plums are progressing through the pit hardening stage, while pears are increasing in size with some pest activity observed.

Insect activity is also being closely monitored. Some pests, such as woolly apple aphids and pear psylla, are active, while others like blueberry maggot and Japanese beetles have not yet appeared. Farmers are advised to rely on trapping and monitoring rather than fixed calendars for pest control decisions.

Weather conditions show above-average rainfall in recent months, with more rain expected. Growing degree days are slightly ahead of normal, indicating faster crop development.

Overall, this update helps farmers understand current conditions and make informed decisions. By managing pests, diseases, and weather challenges, growers can protect crop quality and ensure better yields during the season.
