Abstract
Soil acidification treatments using ferrous sulphate and sawdust mulch were not effective in controlling damping-off losses in forest nursery seed beds at Orono, Ontario. Soil fumigation with methyl-bromide resulted in reduced pre-emergence losses and consequent higher emergences of seedlings. This treatment, however, failed to provide adequate protection during a period of severe damping-off. Total mortality in fumigated beds was comparable to that recorded in untreated beds. The failure of methyl-bromide to provide continued protection during the period of severe damping-off limits its use as a control treatment.
