Hi there, I rent around 5-6 acres off a local farmer for 3 ponies and I apparently have responsibility for weeds etc. Now this has been ok until a recent takeover bid from the common fleabane ( yelowl daisy type plant.) Has anyone any experience of this - any advice on how to eradicate it would be greatly appreciated - oh and is it toxic ? I don't think its easy to get rid of but the thought of pulling by hand is enough to make me go 
. Many thanks.
