Research on the usage of biological control agents (BCA) for the management of basal stem rot disease of oil palm or better known as Ganoderma disease offers a greener solution than synthetic chemical fungicides. The actinomycete is one of the interesting groups of microbes with huge potential to be developed as a biological control agent. Rhizosphere actinomycetes identified as Streptomyces nigrogriseolus GanoSA1 (Streptomyces GanoSA1) showed competent biological control activity in reducing Ganoderma incidence in nursery study. In this article, we described the roles and application of Streptomyces spp, and investigation of S. nigrogriseolus GanoSA1 as BCA against Ganoderma disease of oil palm.

Penggunaan agen kawalan biologi dalam pengurusan penyakit Ganoderma menawarkan pendekatan mesra alam dalam mengurangkan kebergantungan terhadap racun kulat kimia sintetik. Aktinomiset merupakan kumpulan mikroorganisma dengan keupayaan menghasilkan pelbagai bahan bermanfaat yang berpotensi besar dikembangkan sebagai agen kawalan biologi. Aktinomiset pencilan rizosfera, Streptomyces nigrogriseolus GanoSA1 (Streptomyces GanoSA1) telah menunjukan aktiviti kawalan biologi Ganoderma yang baik dalam mengurangkan jangkitan penyakit Ganoderma di peringkat kajian makmal, tapak semaian dan ladang.
