Occurrence of Plant Nematodes in Rice IPM Fields of Rice-Wheat Cropping System in Districts Rohtak (Haryana) and Gautam Buddh Nagar (Uttar Pradesh)

Rice (Oryza sativa L.) is the most widely consumed food for over half of the world's human population, especially in India. Rice production is steady decline due to several factors that could be responsible for the low production. The one of major constraints in rice production is diseases caused by plant nematodes. A study was conducted to know the level of infestation of plant nematodes in rice IPM fields of rice-wheat cropping systems in district Gautam Buddh Nagar (Uttar Pradesh) and district Rohtak (Haryana). M. graminicola and A. besseyi were the most frequent and dominant plant nematodes in the Districts Rohtak and Gautam Buddh Nagar, respectively. The information generated from the present study may be useful from the management point of view in the area.
