Abstract

Eight insecticides were screened in vitro (25, 50, 100 and 500 ppm concentrations) for their effects on the radial growth of Rhizoctonia solani cultured on PDA. The tested insecticides were Milate 10 CG (phorate), Milfen 20 EC (fenvalerate), Milphos36 SL (monocrotophos), Cypermil 25 EC (cypermethrin), Thiodon 35 EC (endosulfan), Metasystox 25 EC (demeton-O-methyl), Nuvan 76 EC (dichlorvos) and Kelthane 18.5 EC (dicofol). All insecticides at all concentrations, except Milphos and Kelthane at 25 ppm, significantly inhibited fungal growth. Only Nuvan at 500 ppm completely inhibited fungal growth, while it provided 85.9% growth inhibition at 100 ppm. At 500 ppm, Kelthane, Thiodon and Milfen provided over 90% growth inhibition.
