Bacillus subtilis (BSCBE4), Pseudomonas chlororaphis (PA23), endophytic P. fluorescens (ENPF1) inhibited the mycelial growth of stem blight pathogen Corynespora casiicola (Berk and Curt)Wei under in vitro. All these bacterial isolates produced both hydroxamate and carboxylate type of siderophores. But the siderophore production was maximum with the isolate(More)
Bacillus subtilis strain BSCBE4 and Pseudomonas chlororaphis strain PA23 (0/P. aureofaciens) were effective biocontrol agents against Pythium aphanidermatum , the causal agent of damping-off of hot pepper (Capsicum annum L.) in greenhouse vegetable production systems. Application of strains BSCBE4 and PA23 at the rate of 20 g kg (1 of seed significantly(More)
Bacillus species are widely exploited as biocontrol agents because of their efficiency in impeding various plant pathogens with multifaceted approach. In this study, Bacillus species were isolated from rhizosphere of various plants viz., carnations, cotton, turmeric, and bananas in Tamil Nadu state of India. Their potential to control the mycelial growth of(More)
The effect of Groundnut bud necrosis virus (GBNV) infection on the life history traits of its vector Thrips palmi and its feeding preference on GBNV-infected plants were studied. A significant difference was observed in the developmental period (1st instar to adult) between the GBNV-infected and healthy thrips, wherein the developmental period of(More)
A severe outbreak of leaf blight was observed in noni crop for the first time in Tamil Nadu and Karnataka states of India during 2008–2009. Based on pathogenicity, morphology and ribosomal DNA spacer sequences, the pathogen was identified as Alternaria alternata (Fr.) Keissler. This report is the first of Alternaria leaf blight of noni.
