Dr. Barrett's lab investigates the physiological basis for herbicide selectivity, herbicide mode of action (including absorption, translocation and mechanism of action), and environmental effects on herbicide activity. Present research areas include: 1) the effect of herbicide protectants on enzyme activities, protein synthesis and herbicide metabolism; 2) environmental effects on herbicide efficacy and crop injury; 3) genetic variation in herbicide response and 4) interactions between herbicides when applied as herbicide mixtures.
