Summary

The paper deals with investigations on the stylar end rot of guava fruits. Fruits in the orchard as well as in storage suffer with this disease, which is, however, of rare occurrence. The symptoms of the disease have been described in detail.

A species ofPhomopsis was constantly associated with this rot and later pathogenicity tests proved this fungus to be the causal organism.

While some infection was obtained through uninjured surface, injury favoured infection. Apart from stylar end rot the fungus was able to cause fruit rot in general.

The morphology of the fungus has been described and its temperature relationship has been studied. The fungus had a minimum temperature for growth near 10° C., an optimum near 25° C. and a maximum of about 35° C.
