Abstract Diaporthe phaseolorum var. caulivora is the major causal agent of stem canker in soybean (CTS) in Argentina. It has appeared mainly in the Southern Pampeana sub-region, but also in warm areas, and it has been observed with different levels of incidence, severity and virulence. The objective of this work was to study the growth rate in vitro and the pathogenicity of isolates from soybean plants at different temperatures. Twenty isolates from Buenos Aires Province were selected. The daily growth rate was measured in nine of them and in two reference isolates in potato dextrose agar (APD), under different light/darkness conditions… More >
