Temporal analysis and fungicide management strategies to control mango anthracnose epidemics in Guerrero, Mexico

Abstract: The temporal progress of anthracnose (Colletotrichum gloeosporioides) epidemics was studied in mango (Mangifera indica) orchards treated with fungicides from different chemical groups, mode of action, and application sequences in two regions of contrasting climates (sub-humid and dry tropics) in Guerrero, Mexico. Full flowering, initial setting, and 8-15mm Ø fruits were identified as critical stages for infection. Epidemics started 20-26 days after swollen buds, and maximum severity was attained at 40-42 days … Show more

“…These results were similar to those reported by Lei et al (2006) and Chanana et al (2005) who observed moderate resistance in "Mallika" cultivar, but contrasted with Nishijima (1993) and Haggag (2010) who reported that "Neelum" and Alphonse" were very susceptible and classified "Fairchild" as resistant. Severity of anthracnose in the field may depend on the complex of species (C. gloeosporioides is the main species found in field) that cause the disease (Lima et al, 2013) and the virulence, population structure, interaction of the isolates that determine the seasonal pressure and fluctuation of inoculum, environmental inductivity and susceptibility of the infected tissue associated with its phenological development (Arauz, 2000;Monteon-Ojeda et al, 2012). Nishijima (1993) propose four susceptibility levels (resistant, moderately resistant, susceptible and very susceptible) while Pernezny and Ploetz (2000) suggest only three levels of susceptibility (highly susceptible, susceptible and moderately susceptible).…”

“…The pathogen also infects leaves, flowers and branches. The disease is more severe under high relative humidity and abundant rainfall; anthracnose may cause loss of production of 50 to 100% in orchards with poor agronomic management (Arauz, 2000;Monteon-Ojeda et al, 2012). Most studies on anthracnose epidemiology or anthracnose pathogenesis emphasize commercially critical phenological stages, such as flowering and fruiting, however mango trees are highly susceptible to anthracnose mango during noncritical stages such as vegetative stage, have higher epidemic rates due to this polycyclic pathogen.…”

“…In the postharvest phase, anthracnose is reported to cause losses of 5 to 20% 6 and the use of synthetic chemical fungicides and treatment with hot water at 52±2 °C for 10 min have been suggested to minimize damage to mango fruits. 7,8 As well as the use of natural and biodegradable biofungicides, such as trans-cinnamaldehyde, citral and phenylacetaldehyde, for the control of anthracnose disease in mango after harvest. 9 Fitzell and Peak 10 determined that spores are the most important source of inoculum in Australia, which are produced on terminal branches, mummified inflorescences, floral bracts and leaves Under laboratory conditions spores are produced over a wide temperature range (10-30 °C) and relative humidity of 95-97%.…”

“…Este fitopatógeno tiene mucha importancia en la fruticultura tropical, por los daños económicos que ocasiona al afectar los frutos. El manejo de esta enfermedad se ha fundamentado en prácticas de control cultural y uso de fungicidas químicos (Monteon et al, 2012;Landero et al, 2016) Dada la importancia del patógeno y su necesidad de encontrar un control químico eficiente, la presente investigación determinó la eficiencia in vitro de fungicidas para el control de Colletotrichum spp., en maracuyá y papaya en Manabi -Ecuador.…”
