, I am sure you must be thinking about, what is the utility of the product? Well, as been told earlier, that farming land if not sprayed properly remains as good as not been sprayed. Hence, this solution which produces visible foam actually gives an indication on which area has already been sprayed, and which has not been sprayed at all. This process actually ensures the full coverage of the total farming area, so that you don't miss a single inch. This method is extremely useful when the farming area is large enough.
