Abstract

Two different neem-derived plant protection products i.e neem leaf extract and a commercial product containing 1% azadirachtin were used to study their effects on M. incognita under in vitro and pot trails under glasshouse conditions. In the in vitro studies, highest concentration (1%) of neem leaf extract resulted in more than 90% mortality in J2 whereas the commercial product did not differ significantly in mortality compared to control. In the pot trials under glasshouse conditions, fresh shoot weight and number of fruits of both the landraces did not differ significantly for different treatments. Zeck scale was found to be the best for evaluation of gall index compared to other scales i.e Garabedian and Van Gundy scale and Mukhtar et al. scale. Gall index decreased in all the treatments compared to positive control and 0.1% azadirachtin was significantly different from the control. This shows that neem-derived pesticides can reduce the galling of roots and can help control M. incognita infestation with proper planning and implementing the treatments.
