Hey guys I should have sprayed my pasture earlier when the muskthistles were in the rosette stage but low an behold I didnt. So now the thistles are bolting an in early bloom. I just have patches here an there so I am going to spray with my 4 wheeler an spot spray. So what chemicals should I use. Remember there are cattle grazing out there right now so I dont want to spray anything that would hurt the cattle. If you have any recommendations let me know an the rate to use. I have a 15 gallon sprayertank. If worse comes to worse I will dig them out with a spade but hopefully the spray will do the trick. BTW idont want to harm the grass with the spray. Thanks for any help.
