Abstract

The herbicide, N-(3-chloro-4-methylphenyl)-2-methylpentanamide was applied to the foliage of tomato, a tolerant species, and eggplant, a susceptible species. Both species increased in tolerance to the herbicide with age but tomato increased at a much faster rate. Selectivity did not appear to be a function of differential wetting of foliage. Photosynthesis was shown to be involved in the phytotoxic action of the herbicide and starvation is suggested as a possible mode of action. Carbohydrates increased the tolerance of tomato plants and the fixation of labeled carbon dioxide in eggplant leaves was prevented by the herbicide.
