GGSPro SolutionsFungal Leaf Spots
Fungal Leaf Spots
*The most common pathogens that cause leaf spots and blights are Alternaria, Botrytis (see Botrytis section), Anthracnose/Colletotrichum, Cercospora, Phyllosticta, Septoria and Rust (see Rust section). Controlling leaf spots can be challenging because symptoms can vary from plant to plant. Signs of a pathogen may not be visible without a hand lens or microscopic examination. It is recommended that you always acquire a lab test from your state diagnostic lab or university to confirm that there is a pathogen associated with the leaf spots or blight. Many abiotic conditions can cause similar spotting. Cultural practices that will help reduce infection include: minimizing leaf wetness and reducing humidity, improving air circulation, and removing diseased leaf debris.
