How sensitive is your crop to dicamba and 2,4-D?

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?

Organic Research Needs and Priorities – Opportunity for Input

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

Managing Bacterial Spot in Ontario Field Tomato Production

Cheryl Trueman, Ridgetown Campus – University of Guelph; Janice LeBoeuf, OMAFRA, Ridgetown

Bacterial spot on tomato plant and fruitBacterial 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.

Fungicide efficacy summary tables for management of diseases in field tomatoes

By Cheryl Trueman, Ridgetown Campus – University of Guelph

About these tables:

  • Efficacy Table - AnthracnoseThese tables were created using results from replicated processing tomato field trials at the Ridgetown Campus, University of Guelph. Please contact the author for more information on research methods and copies of full reports. The tables are for information only and do not guarantee successful results with the use of any product.
  • Always check the most recent version of the product label before applying any product.
  • Only products labelled for ‘control’ of the specific disease are included in each table except where noted.
  • Click on each table to see larger versions.
