Abstract

The effect of light on the response of green beans (Phaseolus vulgaris L. ‘Tendercrop’) and soybeans [Glycine max (L.) Merr. ‘Merit’] to fluorodifen (p-nitrophenyl α,α,α-trifluoro-2-nitro-p-tolyl ether) was evaluated with respect to light quantity, quality and time of exposure. Herbicide-induced injury was intensified with exposure of plants to reduced levels of light. Comparisons of light quality indicated that this herbicide interaction with light was greatest at longer wavelengths of visible light (yellow and red). The most critical time for light exposure to result in increased herbicide injury was at the time of emergence of seedlings.
