The infection process of Colletotrichum truncatum on lentil
The fungus Colletotrichum truncatum (Schw.) Andrus and Moore causes lentil anthracnose, which is a major challenge to lentil production in Western Canada. The pathogen infects leaves and stems, resulting in defoliation, stem girdling, plant wilting, and possibly plant death. Two races, Ct0 and Ct1, …

Molecular and pathological differentiation of colletotrichum truncatum from scentless chamomile and legume crops
The fungus Colletotrichum truncatum is a potential biocontrol agent (BA) against the noxious weed scentless chamomile (Metricaria perforata Mérat; syn.: Tripleurospermum perforatum (Mérat) Lainz) in western Canada. This potential BA, however, is taxonomically related to the anthracnose pathogen on …

RNAi em Colletotrichum lindemuthianum: caracterização das proteínas-chave e desafios para a aplicação
… feijão-comum (Phaseolus vulgaris L.), é o fungo Colletotrichum lindemuthianum. Devido à alta variabilidade genética do patógeno e as limitações das estratégias convencionais de controle, como o uso de cultivares resistentes e fungicidas, torna-se necessário o desenvolvimento de novas abordagens …

Biology of Soybean Anthracnose Fungi and Their Interaction With Other Soybean Fungi (Colletotrichum, Synanamorph, Biocontrol)
… microscopy studies revealed that conidia of Colletotrichum truncatum and Glomerella glycines germinated terminally and subterminally with germ tubes that developed appressoria. Germ tubes were longer when on the midribs than in leaf laminae of soybean (Glycine max). Infection pegs were …

Morphological and molecular identification, pathogenicity characterization of colletotrichum species on soybean, and the resistance of soybean genotypes
Colletotrichum species are filamentous fungi. Many species are important pathogens causing economic losses on a wide range of crop plants. Diseases caused by Colletotrichum species often are referred to as anthracnose. The species associated with soybean [Glycine max (L.) Merr.] have not been …

Studies in the physiology, genetics and pathology of Colletotrichum phomoides (Sacc.) Chester, the cause of tomato anthracnose
Anthracnose of tomato was first described by Chester in 1891. It has been of economic importance to the growers of canning tomatoes nearly ever since. Anthracnose is cause by Colletptrochum phomoides (sacc.) Chester which appears to have different physiologic and morphologic forms. There is …

Determination of the variability of colletotrichum Truncatum, the causal agent of Anthracnose of Soyabean (Glycine max( L) Merr.) in Zambia
… The resullts indicate that the ten isolates of Colletotrichum truncatum posses considerable morphological and physiological variability and therefore their control measures should be directed after knowing which one of the trains of the pathogen is in the population.

Pathogenicity of sclerotia-forming isolates of Colletotrichum truncatum to soybeans (Glycine max) and the effect of soil temperature on root infection
… isolates and a nonsclerotia-forming isolate of Colletotrichum truncatum, causal agent of soybean anthracnose, to soybean roots was studied in an aeroponics system, and their pathogenicity to above-ground parts and effect on yield were examined in the field. The effect of soil temperature on root …

Phylogeny, histological observation, and in vitro fungicide screening and field trials of multiple Colletotrichum species, the causal agents of grape ripe rot
Colletotrichum acutatum and C. gloeosporioides are fungal plant pathogens that have a global distribution, extensive host range, and convoluted taxonomy. Both species can cause grape ripe rot and are considered endemic to Virginia US. In 2012, C. acutatum and C. gloeosporioides were reclassified …
