Post-harvest control of Alternaria navel-end rot with pre-harvest chemical sprays.

ABSTRACT :

 

After the failure to control the navel-end rot (A. citri) on navel oranges with contact fungicides in South Africa, new systemic triazole fungicides (difenoconazole and tebuconazole) were tested to control the navel-end and the dry core rot (A. alternata). The results showed that at more than or equal to 20 g a.i./100 litres water, these fungicides gave good disease control and resulted in residue levels of <0.05 p.p.m.
