EFFECT OF O3, I2 AND CL2 TO COLLETOTRICHUM GLOEOSPORIOIDES PENZ, FUSARIUM OXYSPORUM SCHLECHT, LASIODIPLODIA THEOBROMAE PAT. AND PESTALOTIOPSIS MANGIFERAE P. HEEN. CONTROL
Chlorine and iodine proved to be effective germicides against F. oxysporum, eliminating 100% of the spores, and a concentrated solution at 0.005% of both chlorine and iodine was also most effective against L. theobromae. Chlorine was most successful against P. mangiferae. Ozone applied to this fungi (2.2 mg/l, 15 minute contact) stalled germination.
Based on our findings, we conclude that ozone could be an effective non-residue alternative in suppressing spores of C. gloeosporioides, F. oxysporum and P. mangiferae, particularly when used in washwater and during the hydro-freezing process at packinghouse facilities.
