Ontario Fruit and Vegetable Convention to Feature Topics of Interest to Ginseng Growers

The Ontario Fruit and Vegetable Convention will be held February 17 and 18, 2016 at the Scotiabank Convention Centre in Niagara Falls. For details visit  www.ofvc.ca. In addition to the large trade show and a wide range of general and specific horticultural topics, this year there are a few sessions that will be of particular interest to ginseng growers including Frost Protection and Foliar Nutrients.

In the morning of Thursday, February 18 there will be a session on Foliar Nutrients. It will feature Dr. Thomas Eichert, an expert on foliar nutrient uptake from the University of Bonn in Germany. He will speak on the myths and facts about foliar nutrient uptake, which nutrients are worthwhile to apply foliar vs preplant incorporated, and what bottlenecks there are to effectiveness. Ginseng growers spend a lot of time and money on foliar nutrition and many of those applications may not be effective because of a lack of uptake, a lack of a deficiency, or much better alternative application methods. Here is the session schedule:

  • 9:30 Foliar Nutrient Uptake: Of Myth’s and Legends. Dr. Thomas Eichert, University of Bonn, Germany
  • 10:00 Foliar Tissue Analysis: Understanding the Leaves. Kirk Patterson, Scotland Agromart
  • 10:30 Foliar Uptake: Bottlenecks to Effectiveness. Dr. Thomas Eichert, University of Bonn, Germany
  • 11:00 Foliar Nutrient Products: The How’s and Why’s. Joe Uyenaka, NutriAg

In the afternoon of Thursday, February 18 there will be a session on Frost Protection. Ginseng has had major issue with frost in recent years. Understanding why the frost in 2015 was so damaging and how it could be better managed will help avoid issues in the future. Many growers are purchasing row covers but many questions remain.

  • Row covers can provide protection but how do you when they need to be applied? Why is frost so much worse under shade cloth than the old wood shades?
  • How and when should covers be placed in the garden for most effectiveness against frost?
  • What areas of the garden are most at risk?
  • Are they ways to manage the crop ahead of time to make the crop less susceptible to damage (e.g. irrigation, frost protection sprays)?
  • Are there alternative frost prevention methods that might be useful for ginseng?

Answers to these questions will be provided during this session or in the question period. Speakers have been given photos of the ginseng crop so they are familiar with ginseng production, even though the session will focus on a wide range of horticultural crops. Here is the session schedule:

  • 2:00 Frost Formation, Measurement and Passive Strategies to Avoid Damage. Robert Evans, USDA (retired), USA
  • 2:30 Using Infrared Thermography to Visualize the Freezing Process and Assess the Performance of Frost Protection Measures. Dr. Michael Wisniewski, USDA, USA
  • 3:00 Airflow Machines and Heating Equipment for Frost Protection. Hugh Fraser, Outside the Barn Farm Solutions
  • 3:30 Irrigation and Row Covers for Frost Protection. Robert Evans, USDA (retired), USA
