SUMMARY The severity of banana fruit‐spot (‘speckle’), caused by Deightoniella torulosa , in plantations having abundant leaf trash was greater than in relatively trash‐free plantations. Experimental de‐trashing reduced disease severity to a level at which it ceased to be of commercial importance. Aerial application of fungicides did not control disease, but direct spraying of bunches was effective. Plastic bags put on bunches shortly after ‘shooting’ also provided good control of speckling. Relative costs of various control measures are discussed and associated practical difficulties pointed out. De‐trashing two or three times a year appears to be the cheapest and most practical method.
