SUMMARY In 1969, apple scab was controlled equally well by spraying at 14 or 28 day intervals with benomyl (0.025 per cent a.i.). Triarimol (0.004 per cent a.i.) at 14‐day intervals was even more effective and also surpassed benomyl in controlling apple mildew. In 1970, when the dry summer prevented apple scab development, triarimol apphed at 10‐day intervals again provided the best control of apple mildew. Sprays of thiophanate (NF 35) (0.05 per cent a.i.) and thiophanate‐methyl (NF 44) (0.05 per cent a.i.) applied at 10‐day intervals were no better than the standard captan/dinocap programme, but triarimol and benomyl at 21‐day intervals were less effective.
