Herbicide treatment programme

Foiler spray application
Foliar spray application
Foliage spray application can be carried out through a number of different mechanical means, e.g by knapsack, quad-bike sprayer etc. For larger scale infestations and for works Japanese Knotweed Ireland carries out on public roads, we have a number of specially equipped vehicles acting as mobile spray units.

Weed wiping application
Weed wiping has significant advantages over foliar spraying or spot spraying when treating sensitive areas. The rope or sponge contains concentrated herbicide that can e applied to the targeted plant. With no off spray, wildlife habitats and species rich protected areas are less affected and it makes weed control healthier for you too. The downside is this method of control is far more time consuming, and may not be suitable for large infestations. Larger weed wipers can be towed behind a quadbike, taking adavantage of different heights of plants to apply the herbicide to the target plant.

Stem and Rhizome injection
Stem injection works by injecting a calibrated dose of herbicide directly into each cane of the weed, The herbicide is quickly absorbed by the plant and is translocated through the roots, giving effective control of notoriously difficult weeds. The most effective time to apply herbicides to woody plants is in autumn. At this time, before plant wintering, the remaining nutrients in the plant are drawn back down into the rhizome, thus making it a particularly good stage for it to draw the herbicide into the root also.
