This systemic weedkiller is designed for the toughest perennial and deep rooted weeds including ivy, nettles and invasive species such as Japanese knotweed. The formula travels through the leaves and directly into the root system to deliver a complete kill so the plant cannot return. It is suitable for stump treatment and can kill up to sixteen tree stumps when used as directed from February to November. The pack includes a reusable pipette for precise application on knotweed and other problem plants. Each bottle makes up to twenty five litres of spray solution for broad garden coverage. The concentrated formula is ideal for clearing ground before replanting or tackling stubborn growth that standard weedkillers cannot shift. This makes it a useful choice for gardeners who need a specialist product for targeted, high strength control.
