Anthracnose (Colletotrichum musae) gives latent fruit infections, the symptoms of which generally only become clear as the fruit ripens. Management requires pruning of the trees and applications of fungicides. The fungus survives in seeds and in residues from diseased plants and is spread by splashing water. A review of the etiology and epidemiology of the disease is provided below as background for the various approaches that have been used to manage the disease. Rust-colored specks appear on cotyledons, while petioles, leaves, and leaf veins show brick-red to purple or black lesions. Scolecostigmina mangiferae leaf spots on underside of a mango leaf; they are small, dark, irregular spots. Figure 5. AUTHORS Helen Tsatsia & Grahame JacksonPhotos 1-3,5 Kohler F, Pellegrin F, Jackson, G, McKenzie E (1997) Diseases of cultivated crops in Pacific island countries. However, paucity of genomic information has hindered our understanding of the molecular mechanisms underlying the mango fruit defense response to anthracnose and its effective management. Anthracnose is a major pre‐ and post‐harvest disease on mango, causing direct yield loss in the field and packing plant, and quality and marketing issues thereafter. Post-harvest dips in fungicide (carbendazim) and hot water (both treatments are for 5 minutes at 52°C) control fruit infections, preventing storage rots. Anthracnose (a fungal infection) is the most prominent disease that mango producers must combat. (2005) found that the anthracnose resistance in BTx378 and SC784-5 lines was controlled by a single dominant locus. Shoot blight of mango, caused by Colletotrichum gloeosporioides. At first, the spots are small, black and irregular, often expanding to form large dead areas that dry and fall out. This study has provided a platform to discover causal genes for anthracnose resistance in mango. Orange-pink spore masses develop in the centres of these areas. Adding a spray in autumn, after leaf fall, will greatly increase control. Crop stage-wise IPM for Mango In these cases symptoms can be reduced significantly with a yearly program of fungicide applications. The pattern of the disease on mango is similar to anthracnose on other plants. Glomerella is the sexual stage of the fungus, and Colletotrichum the asexual stage. anthracnose lesion of two mango cultivars Chokanan and Harum Manis. Anthracnose is one of the most common and serious diseases in horticulture. Anthracnose can survive on infected plant debris and is very easily spread.

This used to be a common disease but is rare now owing to the extensive field sprays used to control Mycosphaerella spp. Such fruits may be acceptable for some lower-quality local markets but are certainly not for shipping off-island. On stems, the lesions are sunken and usually elongate. Yield losses due to the disease are usually high when infection occurs in the seedlings. The host gene response in mango fruit against C. gloeosporioides were analyzed using Illumina paired-end sequencing, and expressions of 35 defense-related genes were further validated by qRT-PCR (Hong et al., 2016). Anthracnose and other fungal diseases that attack trees need water (moisture) to grow, propagate, and colonize new hosts. There are different strains, infecting different crops and weeds. This fact sheet is a part of the app Pacific Pests and Pathogens. The word anthracnose means "coal", so fungi that produce dark spots are often given this name. Application of ferbam and copper oxychloride controls the disease to some extent (Dermelj, 1960). It has yet to spread in eastern Australia. Isolation was carried out … Diseased twigs should be removed and burnt along with fallen leaves. anthracnose to some of the registered fungicides, a laboratory study was conducted. Infection is primarily seed-borne, but infected plants rapidly produce secondary inoculum, which can be spread through a crop by wind and rain splash. (2013a). Aspergillus rot is another postharvest disease of mango. Lesions on seeds are brown with a white or reddish center. The anthracnose rot of postharvest mango fruit is a devastating fungal disease often resulting in tremendous quality deterioration and postharvest losses. Further, qRT-PCR analysis of 35 defense-related unigenes, including 17 ethylene response factors (ERFs), 6 genes with nucleotide binding site leucine-rich repeats, 6 non-expressers of pathogenesis-related genes (NPRs) and 6 pathogenesis-related protein (PRs), revealed that most of these defense-related genes were up-regulated after C. gloeosporioides infection. Pink spore masses grow Studies have indicated that resistance to anthracnose might be controlled by multiple genes with different modes of action (Well, 1989) and by a single gene with multiple alleles (Tenkouano, 1993). A.K. 2 Fruit Anthracnose is usually only a problem in fruit that is ripening, as the fungus remains dormant in green fruit during the growing season. The two species are so similar that most people have difficulty distinguishing between them, but the exposed patches on sycamore trunks are much whiter. (2010), and Upadhyaya et al. Anthracnose disease attacks all plant parts at any growth stage. Source: JIRCAS. London plane, a species resistant to anthracnose, is planted extensively as a substitute for American sycamore. Anthracnose resistance has also been mapped as a quantitative trait locus (QTL) by Klein et al. From: Chitosan in the Preservation of Agricultural Commodities, 2016, R. Madhusudhana, in Breeding Sorghum for Diverse End Uses, 2019. Anthracnose was a problem when bananas were shipped as bunches with prolonged shipping times, or when ripened at temperatures above 18 °C. Oblong lesions then develop on the stems often resulting in death of plants. CHEMICAL CONTROLFrequent and timely application of chemicals (e.g., copper oxychloride or mancozeb) is necessary to control Glomerella leaf and flower blight. and is important in bean fields in the region.
