Fungi associated with base rot disease of aloe vera (Aloe barbadensis)

SM Ayodele, EM Ilondu

Abstract


Fungi associated with base rot disease of Aloe vera (syn. Aloe barbadensis) were investigated in Niger Delta Area of Nigeria. Fungi and their percentage frequency were Aspergillus verocosa 28.03%,
Fusarium oxysporium 24.24%, Plectosphaerella cucumerina 16.67%, Mammeria ehinobotryoides 15.91% and Torula herbarium 15.15%. None of the fungi isolated have been previously reported on Aloe vera in
Nigeria. In pathogenicity tests, the fungi isolated produced a variety of symptoms ranging from slowly progressive to rapidly progressive lesions leading to complete disintegration of the leaf bases of A. vera
plants ten days after inoculation. P. cucumerina was the most aggressive rot –inducer which showed full base rot disease after 6 days of inoculation.
