I have moved into a new property and found i have mares tail just about everywhere so i did the research found out what i needed to do and then found your website which seemed very professional in its total approach to the particular problem i had (and others as well). I purchased what was recommended (small pack) and tried it out, worked a treat. Then found i had more come up as time went on and so i purchased a larger pack - i could see it was going to be a long job and so have continued to spray as its appeared. But it works very well so if i keep spraying as the new growth appears i will beat it. Good product, useful and correct information explaining things clearly including H & S info as well.
