Powdery mildew is a fungus that belongs to the Erysiphaceae family and frequently colonizes certain plants. This mold appears in the form of a light velvety white layer or white spots on leaves, which is what makes it immediately recognizable.
The bug often called “cherry fruit fly” is a tiny fly that lays eggs on ripening cherries. It’s also called the “cherry maggot”. Generally, this happens end of May or beginning of June, and can last until July.
Famous for being vineyard owners’ #1 enemy, downy mildew is a constant threat to grape harvests. This blight also threatens certain other vegetables from the vegetable patch such as tomatoes and potatoes, too.
