Research Interests:

Fusarium: DONcast is a model developed and released to forecast deoxynivalenol in wheat for Ontario, the first published for any mycotoxin in the world, and currently the only one that is commercially used and sustained DONcast has resulted in two consulting opportunities with the FAO, one in Uruguay, and one in Iran. DONcast has been in use extensively by Ontario wheat producers since the year 2000 and is delivered by the Weather Innovations Incorporated. It is used as a tool to decide whether to spray a fungicide or not, and also to forecast grain quality before harvest for wheat marketing and health regulatory purposes.

Fungicide and insecticide fungicide application technology: We have become international leaders in developing application techniques to optimize the effectiveness of fungicides for fusarium head blight control in wheat. This work has resulted in well-defined recommendations for producers to optimize these applications and is recognized world wide.

Fusarium: breeding for resistance: We have developed a systems approach to pyramiding genes for resistance to Fusarium head blight in wheat, by combining dihaploidy, molecular marker assisted selection, and in vitro and in vivo selection. We have combined two different sources of resistance (Sumai and Frontana) to Fusarium head blight, into one breeding line. This line (RCAT 33) has been in the top of the heap for resistance to Fusarium head Blight in uniform Fusarium tests for winter wheat lines in the Great Lakes region of North America for the past several years. This line has been released in Crop Science as a parent line and we have sent seed to several breeders around the world.

Mycotoxin assays: : Deoxynivalenol. We have recently acquired an LC-ms-ms to add depth to our mycotoxin research program. We have an extensive applied program to develop an integrated management strategy for deoxynivalenol in corn (forecasting, hybrid selection, fungicide application). We continue to improve our breeding and fungicide efforts to manage DON in wheat. Ochratoxin in stored grains, we are studying and developing an integrated management strategy to reduce the on-farm risk of OTA production in food grains.

Biology and management of Emerging pests: European Chafer in corn and wheat, Soybean aphid, Bean Leaf Beetle, Western Bean cutworm, Brown marmorated stink bug.

Insecticides, fungicides and transgenic Bt in Field crops: We continue to conduct a significant program for developing uses for new insecticides and fungicides in collaboration with the pesticide industry, and the major grower groups for soybeans, corn and wheat. Our program was instrumental in the registration of tebuconazole for Fusarium management in wheat, across Canada, clothianidin as a seed treatment for numerous seedling pests in field corn, methanoxam as a seed treatment for pests in corn, soybeans and edible beans and cyhalothrin-lambda for the control of soybean aphid. Our program has been instrumental in the stewardship of transgenic BT corn to manage a variety of pests in Ontario. Currently we are managing a resistance monitoring program.

For potential graduate students:

I am looking for students interested in applied and integrated pest management systems approaches in field crops, especially those that are interested in working and communicating with end users. Specific research questions include managing mycotoxins in grains, managing introduced crop pests. Practical agricultural experience is appreciated. For more information, please email me.
