Uji Antagonis Pyricularia grisea Sacc. Penyebab Blas pada Tanaman Padi menggunakan Jamur Rizosfer Isolat Lokal
Abstract: Blas caused by
Pyricularia grisea Sacc. is one of disease on rice (Oryza sativa L.). The
disease is controlled using
bio-control agents which
are antagonist to
pathogenic fungi. The
objective of this
research was identify the
fungi from rizosfer
on rice and
to the test
their ability to
suppress the growth
of Pyricularia grisea Sacc. The research was carried out for July
to September 2012 in the rice field in Kalimue Village, Keranji Paidang
Village, Sengah Temila Sub-district, Landak Regency. Isolating Pyricularia grisea Sacc. was conducted based on direct
plantation method. Dilution method and antagonism test using paired method are used
to isolate rizosfer
fungi. Antagonistic fungi
like Aspergillus flavus,
Aspergillus fumigatus, Aspergillus niger,
Curvularia sp., and
Trichoderma harzianum were
successfully isolated. The
result showed the growth
of Pyricularia grisea
Sacc. was inhibited.
The highest suppression
shown by Trichoderma harzianum
isolation was 88.63%.
