Eco-Friendly Management of Root-Knot Nematode, Meloidogyne incognita Using Neem on Cowpea and Mungbean

The experiment was carried out on cowpea (variety- RMG 268) and Mungbean (RG 268) with eight treatments viz Neem cake 5 q/ha (Soil application), Neem oil 10 ml/kg seed (Seed dresser), Neem seed kernel powder (NSKP) 10% (seed dresser), Neem baan 10% (seed dresser), Trichoderma viride 2.5 kg/ha (soil application), Carbosulfan 2% (seed soaking) along with treated check (Carbofuran @ 1.5 kg ai/ha - soil application) and untreated check. The maximum grain yield of cowpea (7.08 q/ha) was recorded in carbofuran with reducing nematode counts from 18.16 to 9.90 followed by carbosulfan (grain yield- 6.00 q/ha: nematode counts- 10.70), NSKP (grain yield- 5.88 q/ha: nematode counts- 10.45), and neem cake (grain yield- 5.28 q/ha: nematode counts- 11.97) over untreated check (Grain yield 2.11 q/ha – nematode counts 18.16). All the treatments were shown significantly higher grain yield and reduced root knot population over control in cowpea. It was also found that the grain yield of carbosulfan treatment (8.64 q/ha) at par with the neem seed kernel powder treatment (NSKP) (8.50 q/ha) followed by neem cake (7.63 q/ha) in mungbean with reducing nematode count from 20.90 to 9.77. The highest grain yield recorded in carbofuran 3G@ 1.5 kg a.i./ha (9.00 q/ha) in mungbean.
