Abstract

The interaction of chloramben and paraquat on weed control and crop safety in peanuts was examined in a series of experiments. Greenhouse experiments revealed that chloramben was antagonistic toward paraquat on sicklepod and peanut, which are species tolerant to chloramben and sensitive to paraquat Control of Florida beggarweed, a species sensitive to both herbicides, was generally improved with tank mixtures. Similar results were obtained in field studies. Antagonism obtained with tank-mixing chloramben plus paraquat was also obtained by applying chloramben prior to paraquat Studies with 14C-labeled herbicides on Florida beggarweed revealed that chloramben inhibited foliar penetration of paraquat, but paraquat had no effect on foliar penetration of chloramben.
