In 2016, Cheryl Trueman compared several different cucumber downy mildew control programs in plots at the University of Guelph Ridgetown Campus. These studies indicated that the highest level of control was achieved using a three product rotation of Orondis Ultra A+B, Torrent and Zampro.
Several different product rotations were compared including:
| Product Rotation | Leaf Area Infected | Defoliation |
| Bravo Only (6 applications) |
45% | 23% |
| High Input | 3% | 0% |
| Low Input | 40% | 20% |
| Single Orondis Ultra in rotation | 28% | 8% |
| Control | 80% | 80% |
Final yields for both the high input and single Orondis Ultra (in rotation) were both significantly higher than the Bravo only programs. The yields for the high input program, were significantly higher than all other treatments.
See the 2017 Downy Mildew Control Strategy for Cucumber Crops for more information.

Are soybeans or tomatoes more sensitive to dicamba? Are sweet potatoes or watermelon more likely to be hurt by 2,4-D? Could crops show visual injury at 1/800th of the rate of one of these products?
In a recent article in Southeast Farm Press, Dr. Stanley Culpepper, University of Georgia Extension weed specialist, shared his data on crop sensitivity (visual injury) to dicamba and 2,4-D. Note that most of this data is from trials in Georgia (and some of the crops on the list reflect that). Continue reading How sensitive is your crop to dicamba and 2,4-D?
The Organic Agriculture Centre of Canada (OACC) is looking for grower input into the Canadian organic research needs and priorities assessment process. The OACC are coordinating this national process on behalf of the Research Needs Task Force of the Organic Value Chain Roundtable. The information collected through this process will be used to guide organic research priorities to direct organic funding, and so it is important that organic stakeholders in Ontario have their say.
To provide your input, please take this short (3 question) survey. The responses will be aggregated anonymously and submitted to the OACC. To learn more or to organize a priority assessment meeting with a group of growers, visit the OACC website. Continue reading Organic Research Needs and Priorities – Opportunity for Input

Bacterial spot, caused by a group of Xanthomonas bacteria, is an ongoing challenge for field tomato growers in Ontario. For many years, a program of fixed copper sprays was used to manage bacterial spot in plug transplants and field tomatoes. Knowing that copper and other products are relatively weak on bacterial disease, the strategy was to suppress populations early in the season while they are still low. Once symptoms are present, the bacterial populations are so high that we would not expect to have a significant impact on disease development with a spray program.
