Spot On Pro Weed & Moss Killer is a glyphosate-free herbicide containing acetic acid. Also known as vinegar, acetic acid causes plant cell membranes to break down resulting in a rapid burn down effect after application. Spot On Pro Weed & Moss Killer contains a much higher concentration of vinegar compared with household vinegar (24% compared with 5%) as well as a surfactant to improve application efficacy. It controls above ground growth quickly and effectively.

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 Weed & Moss Killer also offers excellent control of mosses, particularly on hard surfaces. It is ideal for control of weeds and mosses on any surface where plant growth is not required such as paths, patios and hard standing areas. It is particularly useful for rotation with other herbicides to reduce the likelihood of resistance and for use in areas where glyphosate applications are being reduced.

Product Benefits

  • Can be used all year round
  • Approved for use on hard surfaces
  • Fast acting
  • Controls broad leaved weeds, grasses AND moss

Instructions for Use

Where to use:

Spot On Pro Weed & Moss Killer can be used on hard and permeable surfaces in areas such as paths, roads, playgrounds, parks and tennis courts, 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
  • Natural surfaces not intended to bear vegetation: Areas of soil or natural outcroppings of rock that are 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 Weed & Moss Killer 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 & 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 & 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.

Active Substances

Acetic Acid

Bio-Chemical Mode of Action: Acetic acid has a physical mode of action in which the plant cell membranes are destroyed, leading to the desiccation of the plant.

Mobility: Acetic acid is a contact acting herbicide which means that it will not move into the plant and will only affect the parts of the plant that it directly contacts on application.

Application timing: Because acetic acid is contact acting, it does not require active plant growth to translocate and can therefore be applied at any time of the year.

Resistance: There is no reported resistance to acetic acid.
