When is the right time to spray ragwort?

[myhorsefred]

Hi, I read a post earlier where someone mentioned it was the wrong time of year to spray ragwort.

I was just about to spray my fields this week. eek

When would you say it is the best time to spray? Thanks for any replies.

I always thought the best time was when it was growing usually between May and now.

Ive read lots of places that it is def autumn when its at rosette stage. You would need so much spray when they reach flowering stage which theyve got to that it wouldnt be a good thing. Pull up the flowering ones and spray the rosette ones in autumn (ragwort is biennial so you will have it just as bad next year but after that it should start to improve as you have stoppe seeding now and stopped flowering from next year if you see what I mean)

good luck, our new place has 40 acres of it:-OOOO

Thank you. i pulled it all up a few weeks ago. I am planning to harrow and oversew with a renovation mix in the last week of Sept.

When would you call autumn? Should I spray first and then harrow and reseed, or spray once i've resseded? thanks
