Hi Mark,

 

Not sure who Bob is, but I’ll put in my $0.02.  Bull thistle is biennial and simply keeping it from seeding will, when the seed bank is depleted, be controlled.  Canada thistle is a perennial.  Mowing will have an effect, but other treatments should be included to speed the process.  The rust disease that Dana Berner promoted is effective as far as I know, but it takes a few years before a patch is eliminated.  Attached is a paper that addresses effects of mowing and biological control for Canada thistle.  Hope that helps.

 

Cheers!

Bill

Hi Bob,

 

What is the deal on the species of rust attempted to be used for Canada Thistle discussed at the MISC meeting? 

 

Also, What is the status of effective, host specific, biological controls of Emerald Ash Borer? Thanks.

Hi everyone,

I am in the process of converting some fescue pastures to native wildflower/grass meadows. I use glyphosate to kill off each pasture 3 times (spring-autumn-spring) then seed it. I understand that flushes of dormant weeds (foxtail, oxeye daisy) are common during the meadow establishment. 

Biennial thistles (e.g. bull thistle) are showing up in amazing numbers following our 1st seeding. Should I devote as much energy as possible to killing thistles in our native meadows or will they decrease once the native plants get established?

Thanks to everyone who uses & contributes to this mailing list!
