Control of root-knot nematodes in Kenya with aldicarb and selected antagonistic plants

P. Oduor-Owino


Glasshouse and field tests were conducted to compare the efficacy of the nematicide aldicarb and the antagonistic plants Tagetes minuta, Datura mete!, D. stramonium and Ricinus communis against Meloidogyne javanica on tomato. The nematicide had the most suppressive effect on gall formation and gave the highest shoot growth and fruit yield. R. communis had a significantly greater inhibitory effect on gall formation than did T. minuta D. metel or D. stramonium. Tomato plants grown with any of the four antagonistic plants were better than controls.
