Abstract
Botrytis allii (including B. aclada and B. allii sensu stricto) was detected in latent form in leaf samples in 6 of 16 onion crops sampled early to mid-season in Tasmania, Australia during 1999/2000. Botrytis neck rot was detected in bulb samples from eight of eight crops sampled after harvest at an incidence of 0.4–16.3%, with a mean of 5.3%, and was correlated (r = 0.83, P < 0.05) with leaf infection.
