.Bacterial Leaf Spot: This bacterial disease affects several vegetables, including tomatoes, peppers, and cucumbers. It causes dark, water-soaked spots on leaves, which may eventually turn brown and lead to leaf drop.
Downy Mildew: Primarily affecting cucumbers, zucchini, and other vine crops, downy mildew appears as yellow patches on the upper surface of leaves and a grayish mold-like growth on the underside.
Rust: Rust diseases affect many plants including roses, beans and ornamental plants. It's easy to spot by the orange or red-ish brown patches on leaves.

To prevent and manage these diseases, it's important to practice good garden hygiene, including proper watering techniques, crop rotation, and removing infected plants or plant debris. Additionally, using disease-resistant varieties, providing adequate spacing between plants for airflow, and applying organic or chemical controls when necessary can help keep your summer vegetable garden healthy.
