Population dynamics of root-knot nematode (M. Incognita) on pomegranate

Maximum root knot nematodes were recorded in 52^nd while minimum in 21^st Meteorological week. Highly significant negative correlation coefficient (r) was observed between root-knot nematode population, number of root galls and egg masses and air and soil temperatures. With decrease in temperature, there was corresponding increase in root-knot nematode, root galls and egg masses.
