View Full Version : Dandelion Mycoherbicide

Has anyone seen, used or heard of the fungus Sclerotinia minor to control broadleaf weeds in turf. According to research at McGill University this fungus has been shown to be more effective and twice as fast as lawn herbicides containing 2,4-D, mecoprop and dicamba (Killex or Trikil or Par111). It is expected to be registered for commercial use in several years. Is this the breakthrough we are looking for?

Don't know a thing about it but I'll be listening and looking.

Dan, do you have a link to the research?

Here is the link to the page that I found out about this
(interesting page on biocontrol) (the info you want is near the bottom of the page)
What is totally frustrating is that my search of the web has given numerous mentions but no research or facts. Also this "registration in several years" seems to be taking longer than they thought considering that it was discovered in 1997. I have also found that there is a US patent on it as well.
It was discovered by Dr. Watson at Mcgill university in Montreal but their is very little info there either :blob2:

Another reference but it is at a site that you have to pay to get the full text:blob2:

Didn't understand a word of this one:
Page 4 has a paragraph:http://www.hnd.usace.army.mil/techinfo/CPW/PWTB200-1-19/.%5CPWTB%20200-1-19_AppendixB.pdf
The reason why Sclerotinia minor isn't popular in turfgrass agronomy is that Sclerotinia homoecarpa is commonly known as Dollar Spot.
One typically tries to get rid of Dollar Spot.
The biggest problem, and one the turfgrass breeders haven't completely gotten over, is disease and cultural pressure mutating the selected species.
I am not a crop agronomist, therefore, how Sclerotinina minor effects crops may very well be different than how Sclerotinia homoecarpa effects turfgrass.

In crops it is known as stem rot. That's about all I understood from my Internet "research."
Here's another link...
Doesn't look like we'll be seeing it on the shelves soon.

We may not see it soon but at least there is a little hope on the horizon.
