Vascular Wilt Disease

When we see a plant that look like that, we may immediately think it simply needs more water. What if, however, the addition of water doesn’t perk the plant up? If that is the case, it may be experiencing a plant disease known as Wilt. There are a number of types of Wilt found in Ontario; each is caused by a different pathogenic fungi species. Examples include Verticillium Wilt and Fusarium Wilt.

In this task, you will take the role of a phytopathologist. Using your research skills and independent work skills, find information about the impact of your favourite form of plant Wilt on crops in Ontario. Be sure to ‘lay on the CRAAP‘ really thick, as you only want quality information.

The following websites are good places to start.

Create a report in the form of your choice (audio, video, written, or presentation), a maximum of five minutes if recorded, or to a maximum of two pages if written, that addresses the question you developed using the Q-chart.

Your report should include ideas around:

  • the organism responsible for the Wilt (don’t forget about the binomial naming rules!);
  • the plant it is affecting;
  • the progression of the disease (including method of infection and symptoms);
  • the end result of the infection;
  • any treatment or prevention methods known; and
  • information about the potential impact that the disease has (or could have) on society.

Topic Suggestions…

I went through and sourced an article that provided some examples of wilts and the damage they can cause… might be a good jump off point…

https://www.frontiersin.org/articles/10.3389/fpls.2013.00097/full

It is good and CRAAP-y.  It also has a huge list of references that it pulled its data and points from.  This might be a way to find other good sources.

Fungal Vascular Wilt Pathogens

There are four fungal genera containing the major vascular wilt pathogens: Ceratocystis (vascular wilts of oak, cocoa, and eucalyptus), Ophiostoma (vascular wilts of elm trees), Verticillium (broad host range), and Fusarium (broad host range).

Bacterial Vascular Wilt Pathogens

Seven bacterial genera contain vascular wilt pathogens: Clavibacter (causing ring rot of potato and bacterial canker and wilt of tomato), Curtobacterium (bacterial wilt of beans), Erwinia (bacterial wilt of cucurbits), Pantoea (stewart’s wilt of corn), Ralstonia (southern bacterial wilt of Solanaceous crops and Moko disease of banana), Xanthomonas (black rot of crucifers, bacterial blight of rice), and Xylella (Pierce’s disease of grape, citrus variegation chlorosis)

Oomycete Vascular Wilt Pathogens

Only one oomycete genus, Pythium, contains vascular wilt pathogens.

Create Your Questions

Use the Q-Chart to create questions to tailor your research.  This will support you to reach deeper into the task and look at vascular wilt disease.


References

You need to use books, encyclopedias, journals and magazines (you must have references from at least two of these items) as well as online searching.  You must reference in APA style and use in-text citation in all written work.
