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.

The experiment was conducted to find out red rot disease causing pathogenic reactions of somaclones (R0) and their respective parents at BSRI farm in the cropping season 2011-2012. A total number of sugarcane genotypes 24 including 4 sugarcane varieties viz. Isd 37, Isd 38, Isd 39 and also Isd 40 were inoculated to screen red rot resistant levels (R = Resistant, MR = Moderately Resistant) to susceptible levels (S = Susceptible, MS = Moderately Susceptible, HS = Highly Susceptible) after 7 months of planting. As a result, Isd 37 variety (source/parent) and its somaclones CC–37–12 and CC–37–86 were found to be resistant while 7 somaclones showed moderately resistant reaction. Furthermore, somaclones of Isd 38 variety viz. CC–38–2 as moderately resistant, CC–38–10 as moderately susceptible and also CC–11(38)–8 as susceptible reaction were recorded while Isd 38 variety showed resistant reaction. On the other hand, Isd 39 and Isd 40 source varieties with their somaclones were found as resistant reaction against red rot pathogen. Some somaclones showed different reaction from their source varieties such as moderately resistant somaclones were obtained from resistant source variety Isd 37 while somaclones CC–38–2 as moderately resistant, CC–38–10 as moderately susceptible and somaclone CC–38–8 as susceptible were obtained from resistant source variety Isd 38 against red rot pathogens respectively. Besides, some somaclones showed similar reaction from their resistant source varieties Isd 37, Isd 39 and also Isd 40. It revealed that reaction against red rot pathogen, induced somaclones showed variation with their source varieties. Red rot resistance somaclones were isolated and assessed for the presence of variability through RAPD and SSR markers. Cluster and sub cluster formation verified the presence of variability in the red rot resistance somaclones with respect to the parent.SAARC J. Agri., 13(2): 173-182 (2015)

Resistance of sugarcane varieties to red rot disease is essential for their successful commercial cultivation in Pakistan. Evaluation of sugarcane germplasm for red rot resistance is a basic component of the varietal development system in Punjab. The studies on varietal screening against red rot disease of exotic sugarcane germplasm were conducted at the research farm of the Sugarcane Research Institute, Faisalabad from 2008–2009 to 2010–2011. The screening test was carried out at different varietal development stages including sugarcane nursery-2, nursery-3, semi-final varietal trial, final varietal trial and National Uniform Yield Trial by using plug method of inoculation. In three years, 724 sugarcane genotypes were examined in screening test against red rot disease, which were developed from germplasm (fuzz), imported from different sugarcane breeding organizations of the world. Fuzz is a true seed of sugarcane used to develop new sugarcane variety(ies) through repeated selection in any varietal development program. The results of three years experimentation revealed that 425 genotypes were resistant, 141 moderately resistant, 48 moderately susceptible and 110 susceptible to red rot disease. It was also concluded that sugarcane germplasm belongs to the USA, proved to be superior for resistance to red rot disease with 91% genotypes followed by Brazil and Australia with 86 and 68% genotypes, respectively, which were classified in resistant and moderately resistant category. © 2021 Friends Science Publishers

Rot Disease

Plant extracts and antifungal microorganisms were tested singly and in combination for biocontrol of sugarcane red rot disease ( Colletotrichum falcatum ) using two sugarcane ( Saccharum officinarum L.) cultivars, CoC671 and CoC92061, in pot and field experiments. Leaf extracts of Abrus precatorius and Bassia latifolia and the rhizome extract of Curcuma longa reduced Colletotrichum falcatum mycelial growth by 80%, 58%, and 57%, respectively. Although sugarcane- planting materials (setts) treated individually with either Pseudomonas fluorescens Md1 or A. precatorius in pot experiments had the lowest incidences of red rot, 20.1% and 24.2%, respectively, none of the plant extracts were effective in the field. In contrast, when the two varieties were tested separately in two field locations, the setts treated with A. precatorius in combination with a spray or soil application of P. fluorescens Md1 had the lowest incidence of red rot in both locations, e.g., 3.1% and 3.4% incidence for CoC92061 in one location, and had a similar response to the chemical control. The results suggest the applicability of plant-based extracts for the suppression of sugarcane red rot disease in the field as an environment-friendly tool in combination with antagonists.

In this study, we report on the isolation, identification, and characterization of seven fluorescent pseudomonads isolated from the roots, shoots, and rhizosphere soil of sugarcane and their impacts on the growth of sugarcane plantlets. 16S rRNA gene sequence of five isolates showed close homology with Pseudomonas putida , one with Pseudomonas graminis , and one with Pseudomonas fluorescens . Physiological and biochemical characterizations were determined using API50CH and QTS24 identification kits. The isolates were also subjected to tests for various known growth promoting properties including production of indole acetic acid, the ability to fix nitrogen via the presence of the nifH gene, and ability to solubilize phosphate. Biological control potential was determined from agar diffusion assays of HCN production and production of antifungal compounds against local isolates of Colletotrichum falcatum (that induces red-rot disease of sugarcane). Direct plant growth promoting effects were tested on sugarcane plantlets in tissue culture under gnotobiotic conditions. All seven isolates provided significant increases in fresh and dry masses but only five strains increased shoot height.

Colletotrichum falcatum Went causes red rot disease in sugarcane farming in the tropical and sub-tropical regions. This disease causes significant economic loss to the sugarcane production industry. Successful disease management strategies depend on understanding the evolutionary relationship between pathogens, genetic diversity, and population structure, particularly at the intra-specific level. Forty-one isolates of C. falcatum were collected from different sugarcane farms across Bangladesh for molecular identification, phylogeny and genetic diversity study. The four genes namely, ITS-rDNA, β-tubulin, Actin and GAPDH sequences were conducted. All the 41 C. falcatum isolates showed a 99–100% similarity index to the conserved gene sequences in the GenBank database. The phylogram of the four genes revealed that C. falcatum isolates of Bangladesh clustered in the same clade and no distinct geographical structuring were evident within the clade. The four gene sequences revealed that C. falcatum isolates from Bangladesh differed from other countries´ isolates because of nucleotides substitution at different loci. The genetic structure of C. falcatum isolates were determined using ISSR marker generated 404 polymorphic loci from 10 selected markers. The percentage of polymorphic loci was 99.01. The genetic variability at species level was slightly higher than at population level. Total mean gene diversity at the species level was 0.1732 whereas at population level it was 0.1521. The cluster analysis divided 41 isolates into four main genetic groups and the principal component analysis was consistent with cluster analysis. To the best of our knowledge, this is the first finding on characterizing C. falcatum isolates infesting sugarcane in Bangladesh. The results of this present study provide important baseline information vis a vis C. falcatum phylogeny analysis and genetic diversity study.

Important Cash Crop

Sugarcane is an important cash crop and used as the chief source of sugar grown in tropical and subtropical regions in India. Sugarcane production is challenged by various biotic and abiotic stresses; among the biotic factors, red rot disease caused by Colletotrichum falcatum is a major disease leading to severe reduction in sugarcane production. Five isolates of C. falcatum were established from red rot infected cane varieties collected from different areas of Uttar Pradesh. Cultural and morphological studies of the isolates were conducted in vitro on oat meal agar (OMA).Variations in their conidial and colony characters of the five isolates were recorded and summerized in this paper.
