Current and Prospective Strategies on Detecting and Managing Colletotrichumfalcatum Causing Red Rot of Sugarcane

Abstract

Sugarcane is an important industrial crop because it is the major source of white sugar. It is also one of the crops for the alcohol and biofuel industries. Disease-causing organisms can significantly decrease the productivity of sugarcane plants and sugar quality. Among the disease-causing organisms, Colletotrichum falcatum Went causes the most significant economic loss (5–50%) in the sugarcane production due to red rot disease. This loss results in only 31% sugar recovery. It is reported that C. falcatum can kill sugarcane plants. Currently, there is no sustainable way of preventing red rot disease from spreading in sugarcane plantations. Many popular sugarcane varieties are no longer used in sugarcane cultivation because of their susceptibility to C. falcatum. The objectives of this manuscript were to: (i) summarize existing approaches for the early detection of red rot disease and controlling techniques of red rot disease in the field and laboratory and (ii) assess red rot disease control effectiveness so as to propose better methods for mitigating the spread C. falcatum. If our proposition is adopted or practiced, it could significantly contribute to the mitigation of C. falcatum infection in the sugarcane industry. This could enable achieving sustainable cultivation of sugarcanes to guarantee the sustainability of the sugar industry in the tropics and the subtropics.

Phylogenetic Analysis and Genetic Diversity of Colletotrichum falcatum Isolates Causing Sugarcane Red Rot Disease in Bangladesh

“…The traditional method is less successful due to the assumed presence of intermediate forms between species, morphologic plasticity, and overlapping phenotypic characters. In contrast the molecular biology technique encompasses alternative and supplementary methods for overcoming the difficulties in identifying up to species level [ 63 ]. The molecular method is reputed for enabling rapid identification of isolates and it also clarifies the relationships between fungal organisms [ 64 ].…”

Chitosan and its derivatives: Promising biomaterial in averting fungal diseases of sugarcane and other crops

“…The commercial crop has gained worldwide acceptance due to its huge biomass potential. Over several decades, the cash crop has offered many conspicuous commercial benefits not only for sucrose production but also for ethanol, paper, biofuel industries [2]. It is important to highlight that around 1907 million tons of milling canes are grown and used in the production of 174 million tons of sugar in ~130 countries [3].…”

Impact of carbendazim on cellular growth, defence system and plant growth promoting traits of Priestia megaterium ANCB-12 isolated from sugarcane rhizosphere

“…are re-emerging diseases of sugarcane. In China, these fungal diseases cause serious yield losses (about 5–50%) in commercial sugarcane production ( Liu et al, 2017 ; Xu et al, 2019 ; Hossain et al, 2020 ). Most of these diseases of sugarcane have been associated with several other fungal diseases.…”
