Apple Scab (Venturia inaequalis)
Apple scab is one of the most severe diseases affecting apple trees, causing significant damage to leaves, fruits, flowers, and sometimes even young shoots. Infection occurs under specific climatic conditions (temperature and wetness duration) that favor ascospore germination. The wetness period of susceptible plant tissues determines the severity of the infection—classified as light, moderate, or severe.
After the initial infection, the fungal mycelium spreads and grows within the plant tissues during a phase known as the "incubation period." This stage concludes with the appearance of characteristic brownish spots, where the asexual structures of Spilocaea pomi develop. These structures consist of cylindrical, brown-colored conidiophores, each carrying a single conidium at its tip. The conidia are responsible for secondary infections, which primarily affect autumn fruits.
BioAksxter® M31 Agriculture enhances the plant’s natural defenses, prevents and reduces disease development, and exhibits antifungal properties by strengthening protective epidermal tissues. This leads to increased resistance to climatic stress, minimizing damage caused by drought, acid or persistent rainfall, frost, and sudden temperature fluctuations.
