Abstract

Methyl 1-butyl-carbamoyl-2-benzimidazole carbamate (benomyl) as a dilute foliar spray reduced atomspheric oxidant injury (oxidant stipple) on ‘Ives’ and ‘Concord’ grapevines (Vitis labrusca L.) in 3 vineyard experiments in 1972. Three to 7 multiple applications at 1.12, 3.36, and 6.72 kg/ha increased the protection over unsprayed ‘Concord’ vines. Single and double applications were ineffective. The degree of protection afforded was directly related to the frequency of benomyl application.
