A field trial was conducted to assess the avoidable yield loss of okra cv. Utkal Gaurav caused by root-knot nematode in Odisha using paired plot technique. The application of Carbofuran 3G @ 1.5 kg a.i./ha significantly enhanced the plant growth parameters and yield of okra with significant reduction in root knot index and nematode population under field conditions. Data pooled over two years i.e. 2014 and 2015 clearly indicated that carbofuran 3G @ 1.5 kg a.i. ha−1 significantly increased the fruit yield of okra/ha by 33.9% with simultaneous reduction in root knot nematode population and root knot index by 74.0% and 34.0%, respectively, which resulted an avoidable yield loss to the tune of 25.3%.
