Differential sensitivity of citrus green mould isolates (Penicillium digitatum Sacc.) to the fungicide imazalil.

ABSTRACT :

 

P. digitatum isolates obtained from Australian citrus fruit and from oranges and lemons imported from the USA were compared for their sensitivity to imazalil. In vitro data showed the 4 strains from the USA were up to 13 times less sensitive than the 4 strains from Australia. A similar response was found in in vivo experiments with tolerant strains more difficult to control than sensitive ones. However, the standard application of imazalil in water, as practised in Australia, still provided reasonable decay protection. A growth media concn of 0.1 micro g/ml imazalil was established as a suitable concn for differentiating imazalil tolerant strains. All strains from the USA that were tested were also tolerant to the benzimidazole fungicides and were, therefore, classified as being double tolerant to these 2 different groups of compounds. Two of the Australian strains were also tolerant to the benzimidazoles. All were controllable with the standard application of the fungicide guazatine in vivo.
