Michael Barrett

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.

Dr. Green's primary research interests include weed management programs for grain crops (corn and soybean), forage crops (alfalfa, pastures, hayfields), and non-cropland areas.

The primary goal of my lab is to develop integrated weed management programs for Kentucky’s grain crop producers that combine biological, cultural, chemical, and physical tactics. More integrated methods will help to lessen reliance on chemical weed management while also managing herbicide-resistant weeds and slowing the evolution of new resistant weeds. Cover crops form the basis of many of our research projects – we use cover crops to reduce weed emergence (lower weed density = lower chance of developing resistance) and to outcompete weeds. Cover crop competition against weeds can kill them (= fewer to kill with herbicides), and use resources to keep them smaller (= more effective herbicide applications, and longer windows in which they can be applied). We study how growing cover crops impact winter annual weeds and early spring emerging weeds (like lambsquarters, marestail, common and giant ragweed), and how the residues impact summer annual emergence after corn/soybean/tobacco planting.

Research Interests: Weed control in corn, soybean, and wheat crops. Emphasis on control of herbicide resistant weeds and evaluation of herbicide application technologies for efficient delivery of product to target plants.
