Chemical approach for managing root-knot nematode, Meloidogyne incognita race 2, infecting jute

M. R. Khan

Abstract


Field experiments were conducted for three consecutive years with different nematicides, viz. carbofuran 3G at 2 kg a.i.iha, phorate 10G at 2 kg a.i.iha, sebuphos 10G at 2 kg a.i.lha, fenamiphos or benfuracarb 10G at 2 kg a.i.iha as soil applicants and carbosulfan 25ST at 3 % w/w as seed treatment, for controlling root-knot nematode, Meloidogyne incognita race 2, in jute. The only effective and economical approach was seed treatment with carbosulfan 25ST at 3 % w/w. However, soil applications of carbofuran and fenamiphos at 2 kg a.i.lha were also found effective in increasing fibre yield of jute. Good results were also obtained when seeds of jute were treated with carbosulfan 25ST at 3 % w/w followed by soil application of fenamiphos 10G, phorate 10G, or sebuphos 10G at 2 kg a.i.iha. A reduction of root galling was observed in plots treated with sebuphos at 2 kg a.i. /ha.
