Control of fruit rots of guava by chemical fungicides.

Guava (Psidium guajava) is attacked by a number of postharvest fruit rots including the rots caused by Botryodiplodia theobromae, Colletotrichum gloeosporioides [Glomerella cingulata], Pestalotiopsis versicolor, Phomopsis psidii and Rhizopus arrhizus. Nine fungicides (aureofungin, carbendazim, benomyl, copper oxychloride, mancozeb, imazalil, NAA, guazatine and thiophanate methyl) were tested as pre- and post-inoculation treatments. Bavistin (carbendazim) completely controlled Phomopsis rot and Benlate (benomyl) was most effective against Glomerella rot in both pre- and post-inoculation treatments. Botryodiplodia and Pestalotiopsis rots were effectively controlled by imazalil in the pre-inoculation treatment, while benomyl proved most effective in the post-inoculation treatment. Rhizopus rot was best controlled by copper oxychloride and Planofix (NAA) in the pre- and post-inoculation treatments, respectively.
