Studies on phytocides. I. Diurnal variation in effectiveness of 'methoxone'

Abstract

As determined by the length for which roots were killed, there was no diurnal variation in the effectiveness on skeleton weed (Chondrilla juncea L.) of spray applications of 'Methoxone' at two-hourly intervals over a period of 24 hours. As determined by reduction in growth above the primary leaves, there was a well-marked diurnal variation in the effectiveness on bean plants (Phaseolus vulgaris L.) of drop applications of 'Methoxone.'
