The efficacy of aldicarb, carbofuran and phorate nematicides on the control of wilt disease complex involving Fusarium udum and Heterodera cajani was studied in pot culture. The two pathogens interacted synergistically. The severity of the disease complex was significantly reduced at all the dosages of these nematicides but the greatest reduction occurred at the highest dosage (20 mg a.i./kg soil). The final total population of H. cajani was significantly reduced by F. udum as well as by these nematicides. These nematicides adversely affected not only the developmental stages of nematode resulting in a significant increase in 3rd-4th stage juveniles and decrease in 2nd stage juveniles, adults and cysts, even impeded the fecundity of the nematode.
