The legalities - whilst we're living in crazy times we still need to stay within the law and those restrictions can be found on the label
In summary Max individual dose 3.2L/Ha and total usage in calendar year 16L/Ha. That's the law. Beyond that we go into the specific surface rates (below). These rates have been authorised by the authorities when the product was registered. So to be clear 0.4L/Ha every 7 days is your maximum allowed rate upto 28 times a year on greens.
Label recommendations are grass species, surface and height of cut dependent. It should be remembered that these recommendations are on the label and therefore the law. Huge amounts of work has been invested to ensure the best recommendations are made but every situation is different and in order to gain registrations lines need to be drawn.
