This project is led by Dr. Chris Gillard, University of Guelph, Ridgetown Campus.
- Ongoing studies are investigating the efficacy of white mold fungicides for anthacnose control, the risk of anthracnose transmission associated with various field activities (collaborating with R. Conner, AAFC), disease transmission in a seed processing facility, the efficacy of thermotherapy to control seed/seedling infection (collaborating with R. Conner, AAFC) as well as the genetic control of anthracnose (collaborating with A. Navabi, AAFC). Proposed studies will incorporate new compounds into the seed treatment and foliar control experiments, and augment the genetic control research.
- Ongoing studies are determining the efficacy of thermotherapy to control seed infection (in collaboration with R. Conner, AAFC) from halo blight
- Proposed studies will investigate the efficacy of new seed treatment and foliar controls for CBB.
- White mold is a sporadic yet devastating fungal pest in dry bean. An ongoing study is developing a long term data set on the efficacy of foliar controls – both synthetic chemical and biological fungicides. It is proposed that new compounds (e.g. fluopyram, Coniothyrium minitans, HeadsUp, Contans) are incorporated into this study, and compared to existing controls.
- It is proposed that inoculant products which contain biological controls for root pathogens (e.g. Bacillus subtilis and Trichoderma spp.) be evaluated for their combined benefits of enhanced nodulation and root rot control.
- As WBC becomes established in Ontario, new studies will be needed to track crop damage, pest thresholds, market class sensitivity and the efficacy of control measures
- Proposed studies will look at alternatives to the neonicotinoid seed treatments for control of PLH, as well as new foliar compounds. This work is important to the industry, as neonicotinoid products were recently linked to the widespread collapse of bee colonies in ON.
- Dry bean is an alternate host to SCN, but little is known about resistance genes to manage SCN in this crop. Therefore, other control methods must be evaluated.
- A second study will evaluate experimental seed treatment compounds that have activity on soil nematodes.
