First Report of Colletotrichum karstii Causing Anthracnose on Strawberry in Brazil.

Strawberry (Fragaria x ananassa Duch.) is one of the most important fruit crops worldwide. With increasing cultivated area in the last decades, Brazil has become the largest strawberry producer in South America.

promotes maize growth but fails to control the maize leaf anthracnose.

is an endophytic diazotrophic bacterium and a plant growth promoting bacteria. causes the anthracnose, one of the most destructive maize diseases worldwide. The main objective of this work was to evaluate the effects of SmR1 strain on the plant growth and leaf anthracnose of maize plants grown in substrate amended or not amended with humic substances.

Extracellular enzymes of isolates associated to Apple bitter rot and Glomerella leaf spot.

causes two important diseases on apple in Southern Brazil, bitter rot (ABR) and Glomerella leaf spot (GLS). In this pathosystem, the ability to cause different symptoms could be related to differences of extracellular enzymes produced by the fungi. Thus, the objectives of this study were to compare the production of these enzymes between ABR- and GLS-isolate and to evaluate their involvement on infected apple leaves with .

Modulation of oxidative responses by a virulent isolate of Colletotrichum fructicola in apple leaves.

Apple bitter rot (ABR) and Glomerella leaf spot (GLS) can be caused by Colletotrichum fructicola. Although both diseases can occur simultaneously in orchards, some isolates show clear organ specialization. Thus, this work was aimed to compare microscopically the development of preinfective structures of ABR- and GLS isolates and their impact on the enzymatic oxidant defense system during the leaf infection process.

New insights into the characterization of Colletotrichum species associated with apple diseases in southern Brazil and Uruguay.

Colletotrichum species are associated with Apple bitter rot (ABR) and Glomerella leaf spot (GLS). Whereas both apple diseases occur frequently in Brazil, only the former has been reported in Uruguay. This work was aimed at identifying and comparing morpho-cultural characteristics and pathogenic variability of thirty-nine Colletotrichum isolates from both countries.
