I know this has been brought up before but I have almost given up. Mares tail is rife in some of the gardens I have and in my local area in general and is getting worse.
I have used kurtail and kurtail gold (from progreen) for the last 3 or 4 years, to no avail, I have tried in different gardens at different times, bruising it before spraying, strimming it after it goes black then spraying new growth etc, etc.
After e mailing progreen before buying my lost lot I was told I need to persevere for 3 or 4 years the stuff goes black on the outside very quickly but is still fine inside.
Any help or recommendations as my customers think I am stupid and I cannot charge them for something that doesn't work.
It's probably killing me quicker than the mares tail.
I know about the silica etc and am giving up
