Farmers are advised to clean and repair irrigation canals, dikes, and drainage systems to prevent flooding. Planting should be adjusted according to soil moisture and rainfall conditions, and overly wet fields should be avoided. Proper plant spacing should be maintained to reduce pest and disease incidence. Fertilizer application should be reduced or postponed during heavy rains, and compost or organic fertilizers are recommended to improve soil structure. Regular monitoring for pests and diseases, especially fungal infections, is advised. Integrated Pest Management (IPM) practices should be implemented, and spraying should only be done under favorable weather. Harvesting should be scheduled on dry days, and proper drying and storage of produce must be ensured. Farm tools, machinery, and facilities should be kept clean and well-maintained.
