Abstrakt: Sugarcane (Saccharum officinarum)-a prominent cash crop accounts for around 80% production of sugar worldwide. However, the productivity of sugarcane is declining (~40%) due to the attack of a perilous fungus-Fusarium moniliforme responsible for pokkah boeng (PB) disease. Presently, chemical methods are incisive where their harmful effects on living organisms cannot be overlooked. Introduction of disease-resistant cultivars and other biocontrol measures protect sugarcane to some extent. The multifunctional biopolymers like chitosan (CH) and its derivatives (irradiated chitosan [IRC]), chitooligosaccharides (CO) and nanochiotosan (NCH) offer endless opportunities to spring numerous aids for crops. CH is a dynamic plant elicitor with multifarious antimicrobial properties. The current review unleashes information on CH and its derivatives in controlling PB and fungal diseases of sugarcane along with other crops. We highlight the strategies that deploy CH as "biofungicide" to mitigate F. moniliforme. CH delays the postharvest decay in fruits (apple, strawberry, mango, banana, papaya) and vegetables (tomato, finger millet, capsicum, fenugreek) (~500-1000 ppm). NCH has been utilized as a foliar spray successfully (0.1%-1%) to protect staple crops (wheat, rice, maize) as well. Overall, NCH based strategies are noteworthy to protect sugarcane and other crops.
