Abstract

The nematicidal effect of certain agrochemicals, nutritional compounds and bio-agents on the population of root-knot nematode (Meloidogyne spp.) infecting potato was evaluated through two seasons (2018/2019). The overall reduction percentages in both seasons followed the same pattern and were almost parallel. Oxamyl, abamectin-2%, and azadirachtin were the most effective and significant treatments for decreasing the number of J2S nematodes, with reductions of 77.72 and 85.16 %, 72.40% and 78.41 %, and 72.40% and 78.55% in both seasons, respectively. In both subsequent seasons, garlic oil (54.09 and 53.39%), chitosan (47.54 and 48.32%), and abamectin-1.8% (41.08 and 48.32%) had moderate overall reductions. The nutritional agrochemicals had the weakest overall reduction. potassium silicate (28.73 and 27.30%), EDDHA chelated iron (36.80 and 13.42%), and sulfuric acid (7.06 and 17.22%) for both seasons. On the other hand, abamectin 2% and oxamyl treatments gave the greatest potato yield during both seasons.
