What did you spot spray it with? You've probably killed off the leaves but not the root with the spot spraying. Just dig it out, it'll have a tap root like a carrotI have spot sprayed this Dock twice over the last 6 weeks, and then had the field spayed with docstar, and its coming back again!!View attachment 802968
It's a shame Cimmaron was withdrawn. It would get the root as well.
Trick Is to do that over a few hundred acres!A few drops of roundup on the leaf will kill it

Glyphosate might kill seedling docks but it won't kill established docks. At best the leaves die before fresh growth appears. I've seen it many times in fields that have been sprayed with glyphosate before being reseeded.I couldn't disagree more. Glyphosate does the roots better than anything else. All herbicides are best applied at the rosette stage when it will be taken down to the roots, not when flowering or seeding.

That's what I use and have had good results. Mix it according to the instructions, don't be tempted to add extra, spray at the rosette stage and wet the leaves but don't let it run off.GrazonPro
That's due to the weak rate applied with a boom sprayer. When mixed stronger in a knapsack it slowly kills the dock. Asulox is also very good in a knapsack sprayer if you want to keep the surrounding grass (turns it bright yellow mind but recovers)
Roundup DOES kill them, what you see is new docks from seeds already thereGlyphosate might kill seedling docks but it won't kill established docks. At best the leaves die before fresh growth appears. I've seen it many times in fields that have been sprayed with glyphosate before being reseeded.
I meant before ploughing, the rest of the field is yellow but the docks are still green.Roundup DOES kill them, what you see is new docks from seeds already there
I've killed all the docks in the lawn with roundup
Repeat applications won't be very effective unless you let it green up completely.I have spot sprayed this Dock twice over the last 6 weeks, and then had the field spayed with docstar, and its coming back again!!View attachment 802968
