SUMMARY Numbers of Aphis fabae on spring‐sown field beans were little affected by weekly applications of the systemic fungicides benomyl or tridemorph or the non‐systemic captafol, manocozeb or maneb. Benomyl diminished the mortality of aphids caused by Erynia neoaphidis but not that caused by other species of entomophthoraceous fungi. The other fungicides failed to affect consistently the proportion of aphids infected by any fungus.
