Weed Management Specialist
My research interests are weed management in vegetable crops, the influence of cultural practices and soil fertility on crop-weed competition, and the effect of herbicide residues on production of vegetable crops. The management of weeds in vegetable crops has been a significant component of this research program, and currently is focussed on the development of integrated weed management strategies. Recent or current projects include:
- Effect of topramezone residues on high value crops
- Weed management in processing and fresh tomato
- Critical period and mechanisms of competition in carrot
- Biologically effective rate of sulfentrazone in tomato and pepper
- Use of micro-rates for weed control in red beet
- Weed competition and light attenuation in living mulch systems for sweet corn
