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.
