The Michigan vegetable crop report for late June highlights how changing weather conditions are affecting crops and management practices across the state. Recent storms have caused hail damage in several regions, leading to broken plant tissue. Experts recommend applying protectant fungicides, such as chlorothalonil, mancozeb, or copper, to reduce infection risks. Growers are also advised to delay herbicide applications, as stressed plants may suffer additional damage.
Weather conditions continue to shift, with periods of rain followed by warmer temperatures expected. These fluctuations influence crop development, pest activity, and disease spread. Farmers are encouraged to remain alert and adapt their management strategies accordingly.
Crop updates show mixed progress across different vegetables. Root crops like radishes, carrots, and beets are developing well, though some early pest damage has been reported. In cucurbit crops such as zucchini, cucumbers, and pumpkins, planting is ongoing and harvest has begun in some areas. However, insect pests like squash bugs and cucumber beetles are active and require timely management.
Disease concerns are also increasing. Downy mildew spores have been detected in multiple regions, and new diagnostic tools are helping identify affected crops more accurately. Phytophthora disease has appeared in zucchini fields after heavy rainfall, causing plant wilting and losses. Farmers are advised to improve drainage, use raised beds, and follow crop rotation practices to reduce risks.
In brassica crops, harvesting of broccoli, cabbage, and cauliflower is underway, while flea beetle activity has been observed. Fruiting vegetables like tomatoes and peppers are progressing, with some disease symptoms reported in high tunnels. Nutrient deficiencies, particularly magnesium and potassium, are also common during this stage.
Other crops, including onions, garlic, sweet corn, and strawberries, are advancing through different growth stages. Farmers are urged to monitor for pests such as aphids and plant bugs, although some may not require treatment.
The report also highlights the importance of proper pest management practices. Using sugar as an insect control method is not effective and may lead to unintended problems. Instead, farmers should follow proven Integrated Pest Management practices.
