Benzimidazole-1-carboximid acid esters(I; R1 = Me, Et, CHMe2, R2= ph, C6H4Me-3 CH2CF3, C6H3Me2-, 2-naphthyl, C6H4CI-4, C6H4CO2Et-4), useful as fungicides and insecticides, were prepd. by treatment of 2-(alkoxy carbonyl amine)-benzimidazole with R2OCN. Thus, phOCN was reacted with 2-(methoxy carbonyl amino)-benzimidazole in CHC13 for 5 hr at room temp. to give I(R1 =Me, R2=ph) 81% yield. I was effective against Rhizoctonia solani with 20mg per 1 soil.
