Comparative efficacy of some organic amendments and Granular nematicides in the control of Rotylenchulus reniformis infecting pigeonpea

Organic amendments and granular nematicides improved growth of pigeonpea and reduced population of Rotylenchulus reniformis. Poultry manure @ 0.720 g/pot with 800 g soil increased plant height. fresh shoot and root weights by 157. 500 and 390% respectively with 77% nematode reduction followed by pressmud, a sugar factory by product @ 1.198 g/pot that gave 151, 500 and 380% increase in plant height, fresh shoot and root weights respectively with 73% reduction n nematode population over control. Out of eight different nematicides tried, carbofuran and HOE 388 each @ 2kg a.i./ha and benfurocarb @ 1 kg a.i./ha significantly improved plant height, fresh shoot and root weights and effectively reduced R. reniformis on pigeonpea cv. T 15–15.
