Tomato Disease Workshop LogoThe Tomato Disease Workshop is a scientific meeting held annually in locations around the US and Canada.  In 2014, Ontario is the host.  The workshop will be held on November 4-6 at the Waterfront Hotel in Windsor.

The workshop serves as a venue to discuss all aspects of tomato pathogens and disease management of both field and greenhouse tomatoes. All members of the plant health community are invited to share ongoing research, disease management tactics and strategies, and address emerging issues.

Who Should Attend?
The Tomato Disease Workshop will be of interest to university researchers and students, tomato breeders, extension educators, crop consultants, tomato producers, processors, industry representatives, government regulators and anyone involved in or interested in the successful production of field or greenhouse tomatoes.

Register by October 10 for the early registration discount.  More information can be found on the workshop website.

The Call for Speakers ends on October 10, so a detailed program will be online after October 15.

Cover crops have a lot of places where they can fit in horticultural crop rotations.

  • Before late planted crops like pumpkins to provide weed suppression.
  • After early harvested crops like peas or snap beans to cover and protect the soil while enhancing soil structure.
  • After winter wheat to suppress resistant weeds in the rotation or as a part of the overall crop rotation to suppress nematodes in preparation for planting strawberries.

Midwest Cover Crops Field Guide

Looking for more details on how a cover crop can fit, herbicide concerns, or the basics on a particular cover crop species? There is an improved version of the Purdue Midwest Cover Crop Field Guide available now. The pocket guide, released September 22, is produced by Purdue University and the Midwest Cover Crops Council. The first cover crop guide was released in February 2012. The updated guide is in response to the increasing interest in cover crops in the Midwest and to requests for additional information.

Over the last few weeks we have had a number of questions about “mildew”.  Mildew can refer to either downy or powdery mildew, and it seems that some growers have been confusing the two.  While both cause fuzzy growth on plant leaves, that is where the similarities end.  Downy and powdery mildew are actually very different diseases with different management strategies, and mistaking the two can be costly.

Downy and powdery mildew are common to a wide variety of fruit, vegetable and even some field crops.  They tend to be relatively specific, attacking only one or a few closely related crops.  So, for example, the downy mildew of basil will not affect cucurbits, and vice versa.  Some crops are affected by both a powdery mildew and a downy mildew disease (e.g. hops and cucurbits).

Brown marmorated stink bugAn adult brown marmorated stink bug (BMSB) was caught in a trap at another one of our survey sites in Niagara, near Niagara-on-the-Lake. The presence of adults in traps indicates growers / consultants need to be on the look-out for this pest in their crops. It is very easy to miss BMSB when it is at low levels. This pest is highly mobile, and the adults can move in from adjacent areas at any point in the growing season. See the OMAFRA website for management recommendations. It is likely this will be revised as we learn more about the biology of BMSB in Ontario.

Brown marmorated stink bugs have been confirmed as established (breeding populations) in Hamilton, London, Newboro, St. Catharines, and Windsor, ON. In addition, we have captured adult BMSB in pheromone traps set up on commercial farms near Beamsville, Cedar Springs (2013), Essex, Niagara-on-the-Lake, St. David’s, Continue Reading »
