Management of root: knot nematodes (Meloidogyne spp.) using different chemicals in papaya nursery

Abstract

Various methods are used to manage Phytonematodes under field conditions. Among the various methods, application of chemicals is very popular. While scanning literature, few chemicals are found effective to control Phytonematodes. Therefore to assess the efficacy of new chemicals i.e. fluopyram, Fluensulfone, fluazaindolizine, Chlorantraniliprole, Carbosulfan, Carbofuran and Cartap hydrochloride each @ 3 kg a.i./ha against Meloidogyne spp. were tested in papaya nursery having initial nematode population 310 J2/200 cm3 soil. The result found as an application of fluazaindolizine 500 SC @ 3 kg a.i./ha followed by fluopyram 400 SC @ 3 kg a.i./ha found effective to reduce root-knot nematode population viz., number of females, number of egg mass/3 g roots and number of eggs/egg mass and increase transplantable seedlings of papaya.
