Guarana: Edible Plant

Anthracnose is a fungal disease caused by fungi in the genus Colletotrichum that affects many plants, including vegetables, fruits, and trees. The disease thrives in cool, wet conditions, causing dark, sunken lesions on leaves, stems, flowers, and fruits.

Fusarium is a soil-borne fungus that primarily attacks the roots and vascular tissues of plants. It enters through small wounds or stressed roots, is favored by warm temperatures and waterlogging, and then obstructs the flow of sap. Symptoms include yellowing, often on only one side of the plant, wilting even with moist soil, stunted growth, and, when cutting the stem, internal brown streaks. It frequently affects tomatoes, peppers, eggplants, basil, cucumbers, and zucchini, as well as ornamentals like carnations and cyclamen. In potted plants, it can manifest as root rot with a darkened crown.

Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.

Septoria (often called septoria leaf spot) is a fungal disease that causes many small spots on leaves and can lead to early leaf drop. It spreads in cool, wet weather by splashing water, wind, tools, and hands. Spots are usually tiny, round, and numerous, with dark brown edges and pale gray centers; you may see tiny black dots in the middle of the spots. Leaves turn yellow and drop, usually starting on lower leaves and moving upward. It is common on tomatoes, peppers, eggplant, parsley, and many ornamental plants.
