Indigenous actinomycetes isolated from rhizosphere soils were assessed for in vitro antagonism against Colletotrichum gloeosporioides and Sclerotium rolfsii. A potent antagonist against both plant pathogenic fungi, designated SRA14, was selected and identified as Streptomyces hygroscopicus. The strain SRA14 highly produced extracellular chitinase and beta-1,3-glucanase during the exponential an...

Physalis minima is an herbaceous plant and inhabitant of the porous and organic matter containing soil of bunds in crop fields, wastelands, around the houses, and on the roadsides. S. rolfsii is soil borne and it can infect over 500 plant species of different families. It is of interest to study the pathogenesis of S. rolfsii on P. minima. The S. rolfsii isolated from P. minima (physr1) was cha...

Bacillus subtilis CAF3 adalah bakteri endofit yang potensial dalam menghasilkan senyawa antifungi. Bakteri ini memiliki dapat menghambat pertumbuhan Athelia rolfsii. Produksi antifungi tersebut ditingkatkan dengan melakukan optimasi pada proses fermentasinya. Pada penelitian dilakukan pemilihan media fermentasi, konsentrasi inokulum, pH awal dan agitasi, selain itu juga uji bioaktivitas ektrak ...

Athelia rolfsii is one of the most destructive and aggressive fungal pathogens worldwide causes southern blight disease lettuce. A nonthermal atmospheric-pressure dielectric barrier discharge (DBD) plasma has attracted interest as an alternative control method to chemical usage because its antimicrobial activity. Exposure A. DBD for 5, 10, 15, 20 min resulted in vitro inhibition mycelial discs ...
