Effect of marigold (Tagetes erecta) intercropped with brinjal in different soil types on disease intensity of root-knot nematode (Meloidogyne javanica)

Intercropping of marigold (Tagetes erecta) with brinjal in root-knot nematode (Meloidogyne javanica) infested different soil types exhibited better plant growth characters. Find nematode population was reduced upto 40.5 percent over initial level owing to intercropping of Tagetes with brinjal. Total number of egg masses per plant and eggs per eggmass were minimum in clay soil. However, maximum increase (82.1 per cent) in nematode population over initial level occurred when brinjal was grown done in sandy soil followed by sandy loam and clay soil. Application of carbofuran @ 1Kg a.i./ha though increased the plantgrowth characters and reduced nematode population, yet marigold interculturing with brinjal was significantly superior over carbofuran treatment.
