Roundup Biactive Weedkiller

Roundup Biactive is a powerful, professional-grade systemic herbicide designed to control a wide range of annual and perennial weeds, including difficult and invasive species such as Japanese knotweed. Trusted for its reliability and cost efficiency, it is suitable for use with both knapsack and boom sprayers, making it ideal for gardeners, land managers, and large-scale weed control.

Formulated with glyphosate, Roundup Biactive works by penetrating the leaves and moving through the plant to the roots, ensuring thorough, long-lasting weed control. Its highly concentrated formula delivers excellent coverage, making it a cost-effective choice for treating larger areas.

⚠️ Not clover safe – avoid use where clover is present or required.

Always use plant protection products safely. Read the label and product information before use.
