Screening of endophytic and rhizospheric actinomycetes with potential application for biocontrol of fusarium wilt of Gladiolus

The present study was undertaken to isolate endophytic and rhizospheric actinomycetes from Gladilous and to evaluate their plant growth promoting traits. Out of 90 isolates, 40 were from rhizospheric soil and 50 from roots of Gladiolus plants. Sixteen isolates from rhizospheric and 14 from endophytic were observed to produce IAA ranged from 4.3-79.9 µg/ml. Eighteen (20%) isolates were observed to solubilize phosphate in the range of 6.1- 64.5mg/100ml.
