Anti-fungal efficacy of a botanical formulation "wanis"containing predominantly monoterpene derivatives was evaluated in vitro against sporangial germination of downy mildew pathogen Plasmopara viticola. Wanis at 0.5 per cent completely inhibited the sporangial germination of P. viticola. Post inoculation spraying of wanis (0.5%) controlled grapevine downy mildew incidence to an extent of 67.95 per cent in the green house. In field trials wanis spray at 0.5 per cent reduced the downy mildew incidence by 66.61 per cent. Post inoculation spraying of wanis significantly increased the peroxidase (PO) and phenylalanine ammonia lyase (PAL) activity in grapevine plants after three days of inoculation.Keywords

The project presents robust palm vein recognition using hybrid texture descriptors such as discriminative robust local ternary pattern and Weber’s local descriptor for improving the recognition accuracy. A Biometric system is essentially a pattern recognition system that makes use of biometric traits to recognize individuals. There was a negative effect on recognition performance on fingerprint and palm print biometrics due to the some conditions such as oil on the fingers, moisture, and dirt. Therefore, vein patterns stand out from the host of intrinsic biometric traits for development of a recognition system that can meet all these expectations.
