Abstract
SUMMARY The number of conidia of Gloeosporium album released from infections on the wood of Cox's Orange Pippin apple trees has been measured over a period of 21 months. The application of phenyl mercuric chloride at 0·10 and 0·05% in March 1960 reduced the amount of inoculum dispersed in the period May‐July and there was less rotting of the fruit in store. A similar reduction in sporulation occurred following the application of sprays in autumn 1960 and spring 1961, but spore production was enhanced when the effect of the sprays had disappeared. After an initial application of dichlorophen (5,5‐dichloro‐2,2‐dihydroxy‐diphenyl‐methane) at 0·25% in June 1961, two subsequent sprays were applied, when the records of spores trapped indicated that the previous spray was no longer effective. This treatment also reduced losses from rotting in store.
