What symptom is NOT associated with Rhizoctonia disease in soybeans?

• A. Reddish-brown lesions
• B. Wet, rotting appearance
• C. Dry, stringy hypocotyls
• D. Decayed lateral roots

Answer: (B)

The symptom that is not associated with Rhizoctonia disease in soybeans is characterized by a "wet, rotting appearance." Rhizoctonia is known to cause various symptoms, including reddish-brown lesions on the stems and leaves, dry, stringy hypocotyls, and decayed lateral roots. The disease's symptoms often present as a result of its effect on the plant tissues, leading to desiccation rather than moisture accumulation. While other diseases, particularly fungal issues related to wetter conditions, can lead to a rotting appearance due to excessive moisture or different pathogenic actions, Rhizoctonia tends to be associated with drier conditions and results, which manifest through dry and stringy characteristics and color changes rather than a wet decay scenario. Understanding the specific symptoms of plant diseases is crucial for effective diagnosis and management in agricultural practices, ensuring that interventions are based on accurate symptom identification.
