Management of red rot of sugarcane by integration of biocontrol agents and fungicides

Abstract

Red rot is considered as one of the most dreadful diseases of sugarcane. A field experiment was conducted for management of red rot disease of sugarcane by integration of bio control agents and fungicides at Experimental Farm, Kalyanpur of Department of Plant Pathology, Sugarcane Research Institute, Dr. Rajendra Prasad Central Agricultural University, Pusa (Bihar) over one crop season 2022-2023 with the check variety CoSe 95422. Out of the treatments it revealed that treatment T7 (sett treatment with carbendazim 50 WP @ 0.1% + soil drenching with T. harzianum @ 0.6% + three foliar application with fungicide Azoxystrobin 11% + Tebuconazole 18.3% @ 0.1%) and treatment T8 (sett treatment with carbendazim 50 WP @ 0.1% + soil drenching with T. harzianum @ 0.6% + three foliar application with fungicide Thiophanate methyl 70 WP @ 0.1%) have the potential to control the disease and ultimately enhanced the performance of yield attributing characters, yield and quality such as brix, pol and purity percent. This finding established the fact that integration of bio control agents and fungicides can be used for effective management of the red rot disease of sugarcane.
