Cross-infection Potential of <i>Colletotrichum gloeosporioides</i> Penz. Isolates Causing Anthracnose in Subtropical Fruit Crops

Actividad antagónica de filtrados de Bacillus subtilis contra Colletotrichum gloeosporioides (Penz.)

“…es uno los patógenos de plantas más comunes y de mayor distribución en el mundo, causante de la antracnosis (Chakraborty et al, 1997), que es considerada la más importante enfermedad de frutos en regiones tropicales y subtropicales. C. gloeosporioides se presenta en una amplia gama de hospedantes como chirimoya (Annona cherimola Mill) (Villanueva-Arce et al, 2008), aguacate (Persea americana Mill) (Montero-Talavera et al, 2010), mango (Mangifera indica L.) (Lakshmi et al, 2011) y papaya (Carica papaya L.) (Santamaría-Basulto et al, 2011). Este patógeno se controla con el uso de fungicidas químicos que elevan costos de producción, contaminan el ambiente, presentan riesgos de residuos en productos cosechados y ocasionan resistencia en el patógeno (Lewis y Papavizas, 1991).…”

“…is one the most common pathogens of plants and most widely distributed in the world, causing anthracnose (Chakraborty et al, 1997), which is considered the most important disease in tropical regions and subtropical fruits. It comes in a wide range of hosts such as cherimoya (Annona cherimola Mill) (Villanueva-Arce et al, 2008), avocado (Persea americana Mill) (Montero-Talavera et al, 2010), mango (Mangifera indica L.) (Lakshmi et al, 2011) and papaya (Carica papaya L.) (Santamaría-Basulto et al, 2011). This pathogen is handled with the use of chemical fungicides, which raise production costs, pollute the environment, pose risks of residues in the harvested product and result in pathogen resistance (Lewis and Papavizas, 1991).…”

Molecular characterization of Colletotrichum spp. associated with fruits in Brazil

“…Several studies have demonstrated the lack of host specificity of Colletotrichum species (LAKSHMI et al,2011;PHOULIVONG et al, 2012;de SOUZA et al, 2012;PENG et al, 2013;MACKENZIE et al, 2009, PERES et al, 2002, in which the same species can be associated with different hosts or one host can be affected by different species (FREEMAN, 1998). However, the same species isolated from different hosts might show different cross infection ability and it should be considered when studying new species (PHOULIVONG et al, 2012).…”

“…The most common symptoms associated with the genus are sunken necrotic lesions where orange conidial masses are produced, known as anthracnose (FREEMAN et al, 1998). Even though Colletotrichum has been considered rank highly as one of the most studied and important plant pathogen genera (DEAN et al, 2012;LATUNDE-DADA, 2001), there are many features to understand about Colletotrichum biology and their systematic .…”

“…Another aspect that has made identification of Colletotrichum species difficult is the host range. Several studies have demonstrated the cross infection ability of Colletotrichum species (LAKSHMI et al,2011;PHOULIVONG et al, 2012;de SOUZA et al, 2012;PENG et al, 2013;PERES et al, 2002). Those species, in many cases, are able to infect different hosts or different species can be associated with one host species (FREEMAN et al, 1998).…”
