Program Goal and Research Focus

The overall goal of my research program is to achieve effective and integrated management of weeds and invasive plants through a more in depth understanding of weed biological and ecological principles governing their population dynamics. Also of interest is herbicide bioactivity and herbicide resistance and the use of diverse tactics to manage weeds in a sustainable and economically feasible manner. My research program comprises several main thrusts:

Weed Biology and Ecology Research

This area of research focuses on the effects of such factors as temperature, soil moisture (water layer depth), soil depth, light and fertilizer on emergence and growth of weeds and invasive plants including the troublesome eared redstem, (Ammannia arenaria), Alligator weed, (Alternanthera philoxeroides) and their effects on weed competition in rice and other cropping systems.

Herbicide Efficacy and Herbicide Resistance Research

This research focus aims to assess the influence of environmental factors, weed growth stages, herbicide formulations, droplet size, spray volume, surfactants and additives on deposition of herbicide solutions on weeds. Also of interest is determining the bioactivity and absorption and translocation of herbicides such as glyphosate on problem weeds in our region of China including Alternanthera philoxeroides. Recent work has also sought to determine the molecular basis for herbicide resistance development in target weeds such as Ammannia arenaria and Ammannia coccinea. An additional area of study is evaluating possible synergistic effects of herbicide mixtures and the testing of new herbicides.

Non-Chemical Weed Management Research

Research into non-chemical weed management tactics focus on the efficacy and related physiological and biochemical bases of straw mulching to suppress troublesome weed species such as barnyardgrass (Echinochloa crusgalli) and red sprangletop (Leptochloa chinensis). Also of interest is the effect of the straw mulching on soil fertility and its safety in direct-seeded and transplanted rice and other crops.  

Integrated Weed Management Research

The integrated weed management research makes use of multiple tactics including cultural methods, manipulation of the environment, mulching, biological control, and chemical control, when necessary to effectively manage weeds. This combination of strategies is used in various cropping and non-cropping systems including rice, corn, soybean, vegetables, turf, orchards, forests, and aquatic habitats.
