Rots (fungal)

Virtually all cultivated plants are susceptible to one or more types of rot, including cereals, vegetables, fruits, and ornamental plants. The impact is significant not only during the growth phase, where it causes damping-off or wilting but also post-harvest. Rot-induced losses in storage can reach devastating levels, often ruining the economic value of an entire seasonal yield.

Symptoms typically involve tissue softening, discoloration, foul odors, and the visible presence of mold or mycelial growth. As the infection progresses, roots may decay entirely, causing the plant to wither and eventually collapse. Fruit rots often present as sunken, dark lesions that gradually spread to cover the entire surface, potentially mummifying the affected tissue.

The spread of these diseases is heavily dictated by environmental factors, particularly excessive soil moisture, high humidity, and poor aeration. Warm temperatures often accelerate the growth of fungal pathogens. Furthermore, physical damage from pests, weather events, or poor cultivation practices creates easy entry points for bacteria and fungi to colonize the host plant tissue.

Effective management requires an integrated approach that focuses on prevention. Key strategies include planting resistant varieties, practicing strict crop rotation, and ensuring good field drainage. Chemical control, including seed treatments and targeted fungicide applications, is essential in high-pressure areas. Maintaining proper hygiene in storage facilities is also critical to prevent disease spread after harvest.

• Use of certified disease-free seeds
• Optimizing irrigation systems
• Regular soil health monitoring
• Strategic fungicide application
• Sanitation of storage areas
