As paddy cultivation continues across several regions of India, agricultural experts have raised concern over the rising spread of Sheath Blight, a destructive disease that can severely impact crop yield if left unchecked. Farmers are being urged to recognize the early signs and take timely preventive measures to avoid significant losses.
The disease starts from the leaf sheath, where small greenish-brown spots appear. These gradually spread, causing the plant to dry out completely. Fields with stagnant water and high weed presence are more vulnerable. In severe cases, the infection reaches the topmost leaf, affecting grain formation and reducing productivity.
Since the disease originates from soil, experts recommend thorough field preparation before planting. Farmers should mix 1 kg of Trichoderma in 25 kg of vermicompost or decomposed cow dung and incorporate it into the soil during ploughing. This step can help eliminate harmful pathogens present in the field.
Treatment Measures for Farmers:
To control the spread, experts advise:
Early Action Can Save the Crop: Agricultural scientists emphasize that identifying symptoms in the initial stage and acting quickly with the right treatments can prevent major damage. Even slight negligence can result in heavy crop loss and financial strain.
Conclusion: Sheath Blight poses a serious threat to paddy crops, but with proactive steps—such as soil treatment, timely spraying of recommended fungicides, and ensuring good drainage—farmers can effectively protect their fields and ensure healthy yields.
