Losses Due to Red Rot Pathogen in Cane Juice Quality
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2018, Vol 7, Issue 2
Abstract
Red rot disease of sugarcane is caused by Colletotrichum falcatum Went, a disease of major importance in the most of sugarcane growing state of India. Red rot caused a wide range of reduction in juice quality and also it is responsible for degeneration of varieties in sugarcane. The present investigation was under taken at SRI, Pusa, to assess the deterioration in cane juice quality induced by red rot pathogen. The observation clearly revealed that there was an appreciable reduction in the juice quality i.e. Pol, Brix and Purity. However, the extent of losses varied according to the pathogenic behavior of the isolates and the degree of resistance of cane varieties. Maximum reduction was observed in susceptible genotypes i.e. – CoSe 95422, CoS 8436 and BO 128. The reduction ranging from 16.60 to 20.80 per cent in Brix, 31.60 to 38.26 per cent in Pol and 18.00 to 22.10% per cent in purity. Whereas, minimum reduction was observed in resistant and moderately resistant genotypes which ranged from 2.00 to 8.00% in brix, 6.10 to 19.38 per cent in pol and 4.20 to 12.40 per cent in purity. Therefore, it can be concluded that red rot pathogen impaired the cane juice quality. The resistant variety is the best solution to overcome red rot disease as chemical control measures against red rot is not too much feasible, when it occurred. Thus, during development of sugarcane varieties sincere efforts should be made by Breeders and Pathologists for effective screening of resistant varieties against red rot pathogen.
