Figures & data

Table 1. Growth stages of ‘CDC Grandora’ lentil, dates of inoculation with Botrytis cinerea and dates of boscalid applications at three timings (A, B, C) in field experiments at Outlook and Saskatoon, Saskatchewan, in 2002

Fig. 1 Maximum likelihood phylogenetic tree based on the concatenated partial sequences of heat-shock protein 60 (HSP60), glyceraldehyde-3-phosphate dehydrogenase (G3PDH) and DNA-dependent RNA polymerase subunit II (RPB2) for field isolates BC7, BC8, BC13, BC20 and BC41 from lentil, isolates DAOM 137563A identified as Botrytis fabae, DAOM 192631 and DAOM 231368 identified as B. cinerea from the Canadian Collection of Fungal Cultures, and ex-type isolates B. cinerea MUCL87, B. fabae MUCL98 and B. pelargonii CBS 497.50 (published by Staats et al. Citation2005)

Table 2. Effect of one, two or three boscalid application timings (A, B, C) at three different crop stages on the severity of Botrytis cinerea on, and seed yield of early and late-seeded CDC Grandora lentil in experiments at Saskatoon and Outlook, Saskatchewan, in 2002. Disease severity means with the same letter in each column are not different at P = 0.05. Values in brackets behind mean seed yields are standard errors of the mean
