NS Njombolwana, A Erasmus, PH Fourie - Postharvest Biology and …, 2013 - Elsevier
Imazalil (IMZ) is widely used in citrus packhouses to manage green mould, caused by
Penicillium digitatum. The aim of this study was to investigate green mould control efficacy of
IMZ applied in a wax coating, and the combination of aqueous dip and coating IMZ
applications. Single application of IMZ at 3000μgmL− 1 in carnauba wax coating at rates of
0.6, 1.2 and 1.8 Ltonne− 1 of fruit gave better protective (mean 13% infection) than curative
(mean 70% infection) control of the sensitive isolate. Imazalil residue levels increased (0.85 …
