Abstract

We previously reported that napropamide [2-(α-naphthoxy)-N,N-diethylpropionamide] was highly toxic to achlorophyllous callus of tomato (Lycopersicon esculentum Mill. ‘San Marzano’), whereas foliar application to seedlings was almost without effect. Experiments were performed to ascertain the effects of napropamide on green and achlorophyllous calli of tomato and broadleaf dock (Rumex obtusifolius L.). The growth of achlorophyllous tissues was more severely inhibited. Foliar applications were not as inhibitory in both species. Napropamide was applied to tomato seedlings via roots and cut shoots and root growth was more inhibited than shoot growth. Thus napropamide is toxic to achlorophyllous tissue and is either less toxic to, or detoxified by green tissue.
