Symptoms of celery leaf spot disease include yellow spots appearing on the leaves, followed by gradual wilting and drying of the foliage. The stems may begin to rot, while brown lesions develop at the roots. In severe cases, the heart and inner leaves start to decay, leading to significant yield loss. To prevent and manage this disease, several effective techniques can be applied. First, proper water and nutrient management is essential. Celery thrives in well-fertilized and consistently moist soil. During irrigation, it's recommended to apply urea and potassium dihydrogen phosphate to enhance plant health, strengthen resistance, and reduce susceptibility to pests and diseases. Second, using shade nets can help regulate light exposure. Celery prefers moderate light conditions, and shade nets can lower temperatures, creating a more favorable environment for growth and reducing stress on the plants. For chemical control, early intervention is key. When symptoms first appear, applying 65% mancozeb (diluted 2000 times) or a combination of chlorothalonil and thiophanate-methyl (1500 times dilution) can effectively manage the disease. It's important to follow application instructions carefully and rotate fungicides to avoid resistance. Regular field monitoring and timely action are crucial for successful disease management in celery crops.
