Abstract
SUMMARY Five formulations of four benzimidazole derived fungicides, carbendazim, benomyl, thiophanate methyl and methyl 4‐[2‐(2‐dimethylamino acetamide) phenyl]‐3‐thioallophanate were compared for their toxicity towards two pathogenic isolates of Rhizoctonia solani and three of R. bataticola . The isolates of two fungi showed significant differences in mycelial growth inhibition by the five fungicides. Benomyl and carbendazim were most inhibitory to all isolates of both fungi while the sesame isolate of R. bataticola was least sensitive to all fungicides. Disease control (90%) was obtained with low concentrations of benomyl against root rot of cowpea caused by R. solani , and with thiophanate methyl against root rot of sesame and sunflower, and leaf blight of mung bean caused by R. bataticola . The spread of stalk‐end rot of sunflower heads was best checked with a spray of thiophanate methyl. The results suggest that benzimidazole fungicides having similar toxophores act differently for disease control in different host‐parasite combinations.
