Description
Vitax SBK Tough Weedkiller is a professional-strength systemic herbicide formulated to eliminate stubborn woody and deep-rooted weeds that standard weedkillers often fail to control. Designed for both domestic and commercial use, it penetrates foliage and stems before travelling throughout the plant’s system to destroy growth from the inside out, including the roots. This makes it especially effective against persistent invasive species such as brambles, nettles, docks, thistles, woody shrubs, and tree stumps.
The concentrated formulation is based on powerful selective active ingredients that target broad-leaved weeds while leaving grass unharmed when used as directed. Its versatility allows application by spraying or painting directly onto cut stumps and woody stems, making it ideal for garden clearance, fence line maintenance, and reclaiming overgrown areas. The product is rainfast once dry, ensuring long-lasting performance even in unpredictable weather conditions.
Coverage Rate
Coverage depends on dilution strength and application method. When diluted for general spraying, one litre of concentrate typically treats up to 400–500 square metres. For spot treatment or stump application, coverage extends significantly further due to direct placement on targeted plants.
Drying and Action Time
Drying time varies with weather conditions but is usually achieved within a few hours. Visible results such as wilting and browning generally appear within 1–6 weeks depending on plant type, maturity, and season. Tough woody weeds may take longer as the formulation works through extensive root systems.
