Antagonistic potential of native isolates of Trichoderma longibrachiatum and pseudomonas fluorescens against Alternaria porri (Ellis) Cif.

The aim of the study was to access the anti-bacterial and anti-fungal activity on the growth of Alternaria porri under in vitro condition. The antagonistic activity of bacterial and fungal antagonists (Pseudomonas and Trichoderma spp.) was determined by the dual culture technique both on King’s B and PDA media respectively, Paper disc assay and Agar well mathod. Plates were incubated at 28ºC for 7 days and 2 days. The antagonistic activity of these antagonists was evaluated by mycelial growth and mycelial dry weight of test fungus (Alternaria porri).

Potentiality of native pseudomonas spp. in promoting sugarcane seedling growth and red rot (Colletotrichum falcatum went) management

Eight native strains of Pseudomonas spp. were isolated from rhizosphere of various sugarcane clones on Pseudomonas agar using standard protocols. These strains were characterized for antagonistic traits on red rot pathogen in vitro and Plant growthpromoting (PGP) activities in greenhouse up to 30 days from single node setts in portrays as sett treatment (@109 CFU ml-1 ). The promising isolate was characterized up to species level by PCR amplification of 16S rDNA region using Pseudomonas specific primers. Elite strain was identified as P. putida strain AKP-1.
