This webinar recoring is made up of the following two presentation:  Weed Control Considerations for Organic Tomato Production and Recent Viroid Disease Outbreaks in Greenhouse Tomatoes in North and Central America and Their Mgt.

Weed Control Considerations for Organic Tomato Production
Controlling weeds is the number one problem for many organic vegetable farmers. Weed control in tomato may involve the use of different kinds of mulches, flaming, or herbicides that are approved for organic production. The connection between weed control and soil quality may not be immediately apparent, but on close examination the two are intrinsically linked. In this video, we will explore aspects of that linkage and look at how good soil management may create an environment less favorable to weed growth. In particular we will explore the idea of "soil balancing", popular with organic farmers, and lay out a scientific basis for why a balanced soil may create an optimum environment for crop growth that will be very competitive with weeds. Viewers will all gain a better understanding of soil balancing and how the judicious use of limestone and gypsum can improve soil quality. You will learn what is meant by "soil balancing", and the science behind the theory of the basic cation saturation ratio approach to soil management. You will learn to recognize the facts about soil balancing as well as the pseudo-science that is so commonly encountered on this subject. Finally you will also learn about other tried and proven techniques that will help you get weeds under control.

Recent Viroid Disease Outbreaks in Greenhouse Tomatoes in North and Central America and Their Mgt
This presentation will help viewers in North America and around the world to better understand the emerging viroid diseases of tomato, their distribution, detection and management tactics. Specifically in this presentation, practitioners will learn: the recent viroid disease outbreaks, what are viroids and their transmission through seed and mechanical means; what key factors affect viroid disease epidemic in a greenhouse; technologies in disease diagnosis and viroid detection; and which chemicals are the most effective disinfectants to prevent viroid mechanical transmission. By the end of this presentation, the practitioner should know more about the tomato-infecting viroids, their diagnosis and detection. With the knowledge regarding the factors affecting viroid disease epidemiology, the practitioner should know how to prevent and manage a viroid disease outbreak in greenhouse tomatoes.
