Colletotrichum Species Complexes Associated with Crops in Northern South America: A Review

et al. 2022

View full text Add to dashboard Cite

Colletotrichum genus comprises a high number of plant pathogens causing anthracnose disease in different tropical and non-tropical crops. We aimed to review northern South American studies in the online SCOPUS database to: create a taxonomically updated list of the species complexes found in the region, describe their most important phytopathological characteristics, revise the methods used in the region to control disease, and discuss the role of fungus as a plant endophyte. A total of 19 Colletotrichum species within five complexes—acutatum, boninense, gigasporum, gloeosporioides, and orbiculare—have been reported in northern South America. Few studies have been conducted, particularly in Peru and Ecuador, despite the diversity of Colletotrichum hosts cultivated in the region. Important information can be extracted from our review: species do not appear to show host specificity, although some isolates show host preferences, certain plant species can host several Colletotrichum species, some studies show the importance of using plant extracts to control the disease, but biological control using microorganisms is certainly an open area of research in the region. In northern South America, only a few hosts have been reported to harbor Colletotrichum as endophyte, and the potential of these endophytes as biological control agents has not yet been explored.

“…Rigidoporus microporus, a causal agent of white rot, is a major disease affecting tropical rubber trees and some crops worldwide (Andrew et al, 2021). The fungus Microcyclus ulei, which is the primary cause of Southern American leaf blight (Castro-Navarro et al, 2020), irregular defoliation caused by Phytophthora species (Churngchow & Rattarasarn, 2000), and powdery mildew caused by Oidium heveae are among the severe diseases of rubber trees.…”

Rubber trees are important sources of agricultural income as they are utilized for lumber and latex. Like other crops, they are susceptible to numerous fungal pathogens, especially on their leaves, the most important plant part. Therefore, this study was conducted to identify the fungi associated with leaf spot disease on the leaves of rubber trees. This study aimed to characterize fungi associated with diseased rubber leaves and determine the causative agent of leaf spot disease. A total of 20 fungal isolates were obtained and purified from rubber leaves collected during sampling in rubber plantations in Pahang, Malaysia. All the isolated fungi were identified as Colletotrichum siamense (2 isolates), Diaporthe sp. (5 isolates), Lasiodiplodia pseudotheobromae (1 isolate), L. theobromae (7 isolates) and Neoscytalidium sp. (5 isolates). Based on a pathogenicity test, it was found that nine isolates were pathogenic towards the leaves of rubber, which were L. theobromae, L. pseudotheobromae, and C. siamense. The lesions on the leaves displayed chlorosis with varying necrotic lesion sizes after 21 days post-inoculation. The isolates of the species L. theobromae were the most prevalent, indicating it is more widespread in the region than other species. The findings present data on the potential pathogen of rubber plants and are important to understand further the potential risks and effects of the pathogen in rubber plantations

Estimulación de árboles de caucho bajo diferentes frecuencias de sangría en el Noroeste de Colombia

et al. 2022

View full text Add to dashboard Cite

Las plantaciones de caucho natural del Bajo Cauca antioqueño requieren una alta intensidad de sangría. Esto genera un mayor costo de la mano de obra y sobreexplotación, razón por la que se evaluaron parámetros fisiológicos y de producción en árboles de caucho del clon FX3864, los cuales fueron sometidos a distintas frecuencias de sangría y estimulación química en el Nordeste de Antioquia, Colombia. Se comparó la producción de látex y el contenido de sacarosa, fósforo inorgánico, tioles y sólidos totales en plantas estimuladas con etefón al 2.5 % y sometidas a tres frecuencias de sangría (cada dos, tres y cuatro días). La mayor producción de látex se alcanzó en árboles estimulados y sangrados cada cuatro días (170.99 mL d-1 por árbol), sin indicios de sobreexplotación para esta frecuencia. La estimulación y la disminución de la intensidad de sangría del árbol de caucho aumentan el rendimiento sin alteraciones metabólicas significativas.
