Brief Achievements
Imported, quarantined and established the host-specificity of the rust fungus, Puccinia spegazzinii, for classical biological control of the invasive weed, Mikania micrantha, in India
Through collaboration with CABI Bioscience, UK, identified two rust fungi, Puccinia abrupta var. partheniicola and P. melampodii, as potential classical biological control agents for the serious weed, Parthenium hysterophorus, in India.
Discovered a number of endemic fungal pathogens of Cyperus rotundus, Parthenium hysterophorus, Eichhornia crassipes and Salvinia molesta, and established their potential as mycoherbicides
Developed the first Indian mycoacaricide (Mycohit) based exclusively on the acaropathogenic fungus, Hirsutella thompsonii, for field use against the coconut eriophyid mite, Aceria guerreronis
Introduced the term plant growth-suppressing rhizobacteria (PGSR) in biological weed control
