Corn Sheath Blight Studies and Control (Paperback)

Corn Sheath Blight Studies and Control By Shastri B Cover Image


description: Corn sheath blight is a devastating fungal disease that affects corn plants, leading to significant yield losses and reduced grain quality. It is caused by the fungus Rhizoctonia solani, which infects the sheath tissue surrounding the corn stalks. This disease primarily occurs during periods of high humidity and warm temperatures, making it a common problem in tropical and subtropical regions. The symptoms of corn sheath blight typically appear during the reproductive stage of the corn plants. Infected plants display lesions on the lower leaves and sheaths, which gradually expand and turn brown. As the disease progresses, the lesions may merge, causing extensive damage to the plant. Severe infections can result in premature death of the corn plant and a significant reduction in grain yield. To control corn sheath blight, an integrated approach is necessary. Cultural practices such as crop rotation, proper spacing between plants, and removal of crop residues can help reduce the incidence of the disease. Additionally, choosing corn varieties with resistance to sheath blight can provide a level of protection. Fungicide applications are often employed to manage corn sheath blight. Fungicides containing active ingredients such as azoxystrobin, pyraclostrobin, or boscalid have shown efficacy in controlling the disease. Timing of fungicide application is crucial and should be based on disease development and environmental conditions.

Regular scouting of corn fields is essential to detect the early signs of sheath blight and initiate appropriate control measures promptly. By implementing a comprehensive management strategy, farmers can minimize the impact of corn sheath blight and safeguard their corn crop from this destructive fungal disease.
