In order to prevent inadvertent introduction of exotic pathogens in India, 31 fungi and one bacterium were intercepted in crop germplasm belonging to 26 species from 21 countries during 2011. A number of economically important pathogens, not yet reported in India (Phomopsis longicolla); having more virulent races (Bipolaris maydis, Puccinia helianthi); wide host range (B. sorokiniana, Fusarium solani, F. verticillioides and Macrophomina phaseolina); and pathogens from unrecorded hosts such as Cephalosporium maydis on Capsicum annuum; Bipolaris sorghicola on Solanum lycopersicum and Raphanus sativus; F. verticillioides on Arachis duranensis, Calopogonium mucunoides, Calotropis ensiformis and Stylosanthes viscosa; M. phaseolina on Aeschynomene falcata; Periconia circinataon C. annuum and Phoma glomerata on C. mucunoides were intercepted and infected/contaminated samples were salvaged prior to release. Therefore, salvaging of the infected/contaminated material is of paramount importance to release pest-free material for biosecurity in the country.
