Pg. 38-40 Evaluation of post-harvest applications of fungicides and fungicide mixtures for control of litchi decay

Litchi fruit were dipped in solutions of prochloraz, fludioxonil, guazatine, Sporekill or Des-O-Germ, alone and in combinations, in order to reduce post-harvest decay. Disease pressure due to natural infection was low in this trial. Results showed that mixtures were more effective than individual fungicides applied as dip treatments. Concentrations of individual fungicides could be lowered when applied as mixtures, with enhanced efficacy. Post-harvest decay was mostly caused by Alternaria, Botryodiplodia, and Pestalotiopsis spp. Penicillium spp. was noticeably absent during this trial.
