OCP Slasher Weedkiller Concentrate is a contact weedkiller made from plant extracts, with no glyphosate in it. It burns off the green tissue the spray lands on, and most weeds show visible damage within an hour. The 1 litre bottle is a concentrate, and it also controls moss, algae and lichen.
What it does
-
Visible within the hour. Most weeds show damage within one hour of a thorough spray, which makes it obvious what you have covered and what you have missed.
-
Glyphosate free chemistry. The formulation is plant extract based and contains no glyphosate.
-
More than weeds. Moss, algae and lichen are controlled as well, so the green film on shaded paths and pavers is dealt with by the same bottle.
-
Nothing to wait out. There is no withholding period required, so it can be used around a vegetable patch without a delay before picking.
How to use it
Dilute with water according to the label instructions, then spray directly onto the weeds, moss, algae or lichen you want gone. Rates, the situations it is registered for and every restriction are on the label, and the label directions must be followed. Coverage decides the result: this is a contact product, so any leaf the spray misses carries on growing. Choose a still day, wet the foliage properly rather than misting over it, and repeat as required on regrowth.
What it suits
Paths, pavers and driveways. Hard surfaces are where a contact weedkiller does its best work, because the weeds there are shallow rooted and there is nothing nearby to damage by accident.
Beds and the vegetable garden. Around edible plantings it has a genuine place, given there is no withholding period, though a still day and a shield over anything you want to keep are worth the trouble.
Clearing before mulching. Knocking weeds down ahead of laying mulch is faster than pulling them. It is delivered Australia wide, with delivery from $29.95.
Be clear about what it is not. It is non-selective, so it damages any green tissue it touches, lawn and garden plants included, and it works on contact rather than through the roots, so established perennial weeds regrow from below and need repeat treatment.
