SUMMARY In a factorialized field trial cells of Bacillus subtilis or phenylmercuric nitrate (PMN) were applied as sprays in autumn to manually defoliated apple trees, cv. Bramley's Seedling, artificially infected with Nectria galligena. Trees were additionally sprayed with dithianon at intervals in May and June or left unsprayed at this time. B. subtilis in conjunction with dithianon, and PMN with dithianon were equally effective in the control of canker over a 2‐yr period. Dithianon alone gave some control, as did PMN but B. subtilis was not effective without additional applications of dithianon.
