Pengendalian Penyakit Antraknosa Disebabkan Oleh Colletotrichum Sansevieria Pada Tanaman Sansevieria Trifasciata Prain. Menggunakan Trichoderma Spp. Endofit Isolat Lokal Riau
Sansevieria trifasciata is a decorative plant and has a great interest because it
can absorb more than 107 elements of harmful pollutants. Sanseviera spp is one
of the world’s export plants. This plant is often infected by anthracnose disease
caused by Colletotrichum sanseviera. Disease control using intensive chemical
fungicides will harm the environment and humans. Endophytic Trichoderma is a
biological control agent that can inhibit pathogenic fungi. This study aims to
determine the ability of Trichoderma to inhibit fungal pathogens on S. trifasciata.
The data obtained were analyzed by variance and then tested by a 5% level of
DMRT test. In vivo assay with the spray prick method. The results showed that T.
harzianum treatment had the highest inhibition against C. sansevieria produced
32.25 spots, while T. aureoviridae is the lowest with 37.50 spots. The results of
leaves histopathology showed that there were differences in the shape of
the Sanseviera leaf cells that had been treated with positive control and treatment
with Trichoderma.
