A comprehensive exploration with referenceto sugarcane red rot caused by Colletotrichum falcatum

Red rot disease, of sugarcane caused by Colletotrichum falcatum, poses a significant threat to sugarcane cultivation in India, particularly in the states of Bihar and Uttar Pradesh. This disease has been responsible for the elimination of several popular sugarcane varieties, leading to substantial reductions in cane production and productivity. Incidence rates of red rot disease have been reported to range from 30% to 50% within India, and trace to 50% across various cane-growing regions globally. The impact of this disease extends to crucial cane parameters, including cane weight, brix, pol, sucrose content, and purity, which collectively contribute to significant economic losses. Extensive studies have been conducted to understand the morphological characteristics and pathogenic behavior of Colletotrichum falcatum. In addition, various control methods have been tested both in-vitro and in-vivo to mitigate the disease. These methods include chemical treatments, botanical approaches, biological controls, and heat therapy. Each of these control strategies has been assessed for their effectiveness in reducing disease incidence and severity. Furthermore, research has explored the influence of intercropping and crop rotation on red rot disease and associated cane parameters. The role of micronutrients, temperature, and pH value in influencing disease incidence and severity has also been a focal point of study. Overall, the concerted efforts of researchers in studying various aspects of red rot disease and implementing diverse control methods aim to enhance the resilience of sugarcane varieties against this detrimental pathogen. The ongoing evaluation of resistant varieties, coupled with optimized agricultural practices and environmental management, holds promise for sustaining sugarcane production and minimizing the losses caused by red rot disease in India and other affected regions. The study faced challenges from the high variability of Colletotrichum falcatum and difficulty in standardizing control methods across regions. It contributed by advancing red rot pathology research, evaluating diverse control strategies, and promoting resistant varieties for sustainable management.
