Spot On Pro Weed and Moss Killer is a fast working, glyphosate-free, non-selective herbicide which can be used to control all unwanted grasses, broadleaved weeds and mosses on hard surfaces, natural surfaces not intended to bear vegetation and permeable surfaces overlying soil. Spot On Pro Weed and Moss Killer can be used at a rate of 25 ml/m2 up to six times per year.

Made from acetic acid, Spot On Pro Weed and Moss Killer causes plant cell membranes to break down resulting in a rapid burn down effect after application. Spot On Pro Weed and Moss Killer breaks down rapidly in the soil, leaving no residual effect once weeds have died back. When used on small weeds within 2 weeks of germination, complete control can be expected within 24 hours. On established perennial weeds and grasses repeat applications may be required. Spot On Pro also offers excellent control of mosses, particularly on hard surfaces.

Spot On Pro Weed and Moss Killer is an ideal glyphosate-free herbicide providing rapid control of weeds and mosses throughout the year. Spot On is based on natural ingredients which will biodegrade on soil contact. It is recommended for use by Royal Horticultural Society (RHS) for control of liverwort and can be used around the base of roses, trees and under established hedges.

Spot On Pro Weed and Moss Killer can be used on hard and permeable surfaces in areas such as paths, roads, playgrounds and parks, churchyards, industrial sites, fence lines and similar:

  • Hard surfaces: Any artificial impermeable surface, such as concrete or asphalt that is not intended to bear vegetation

  • Permeable surfaces overlying soil: Any artificial permeable surface such as gravel that overlies soil and is not intended to bear vegetation

When to use:

Spot On Pro can be used all year round, whenever weeds or mosses are visibly present on hard, permeable or natural surfaces.

How to use:

Spot On Pro Weed and Moss Killer should be applied using handheld application equipment such as a knapsack sprayer using a nozzle with a coarse spray quality . Because Spot On Pro Weed and Moss Killer is a contact acting herbicide it is important that leaves and stems are fully wetted to ensure a good level of control. Small weeds within 2 weeks of germination should be fully controlled within 24 hours of application. However, established perennial weeds may require repeat applications. For good control of mosses, ensure the surface is dry, repeat applications may be required if moss growth is thick.
