Management of Meloidogyne incognita Race-1 and Rotylenchulus reniformis by seed treatment with biological agents, organic cakes and pesticides on cowpea.

The seeds of susceptible cowpea cv. Pusa Komal were treated with Pseudomonas fluorescens @ 10 g/kg, Trichoderma viride @ 4g/kg, neem seed and jatropha seed kernel poweder each @ 10% (w/w), cartap hydrochloride 50 (SP) @ 1.5% (w/w) and carbosulfan 25 (DS) @ 3% (w/w). Soil application with carbofuran (3G) @ 2kg a.i/ha. was also included as treated check. Root-knot nematode @ 2J2 /g of soil and two young females alongwith equal number of males/g soil of reniform nematode were inoculated after 10 days of germination. The observations indicated that the growth parameters of cowpea plants were better and population level of both the nematodes were declined in all the treatments used when compared to inoculated control.
