ABSTRACT
The export oriented agricultural and
horticultural crops depends on the export of residue free produce and has
created a great potential and demand for the incorporation of biopesticides in
crop protection. There is several fungicides which are causing harm to soil,
plant and environment. So, we focus on isolation of such bacteria which having
antagonistic property as well as phosphate solubilizing ability for growth
promotion. We isolated approximately 54 isolates which having phosphate
solubilizing ability from different regions of eastern and western regions of
Uttar Pradesh from rhizospheric soil of parthenium
plant. Among these bacteria we screened for antagonism test against TLB,
and 4 bacteria were found which were showing strong antagonism against TLB.
Biochemical test were also performed of these bacteria, for Indole acetic
production. Among them G1, G7, G13 and G17 produce Indole acetic acid 180µg/ml,
200µg/ml, 220µg/ml and 330µg/ml respectively. These strains have been selected
for further studies towards application as BCAs against TLB as well as good
plant growth promoting activity. So in
this way we can use this strain in future for development of antifumgal
chemical which used as a antifungal against TLB and ecofriendly.
