The fate of the fungicide in stored citrus fruit treated with wax coatings containing either sodium 2‐phenylphenate (SOPP) or biphenyl was studied. The 2‐phenylphenol content of SOPP—treated fruits was virtually unchanged during storage, was localised in the peel and could not be detected in the vapour phase. The persistence of this fungicide on fruit is in accord with the satisfactory results obtained with SOPP waxes. Biphenyl volatilised from biphenyl‐waxed fruit at rates reflecting the conditions of storage. The volatilisation of biphenyl accounts for the protective action of biphenyl‐waxes and their time limited effect. Copyright © 1972 John Wiley & Sons, Ltd
