Completed my second test with MO Bactor and can confirm that it was a dismal failure. Out of an area of 200sq.metres there was a small patch about the size of two dinner plates where the moss turned grey.
I think that whoever gave this product an award should be taken to task. They should publish the results of any independant tests that were carried out. (or did they just accept the word of the manufacturers and distributers).
There is another company in Belgium that makes a very similar product but they do not claim that it eradicates moss - I wonder why?
There must be a reason why MO Bactor works to eradicate moss on a few lawns but fails on the majority. Is it to do with the ph of the soil?
