Chikara Weed Control is a highly effective residual herbicide for professional use, offering long-lasting control of both annual and perennial broadleaf weeds. With its active ingredient Flazasulfuron (25% w/w), Chikara provides up to 5 months residual protection when used at higher application rates. It is ideal for hard surfaces, fence lines, gravel paths, and amenity vegetation zones where long-term weed suppression is essential.
Available in 50g and 150g packs, Chikara is applied via knapsack or boom sprayer and is rainfast within 3 hours. It can also be tank-mixed with glyphosate for even broader spectrum control, making it an excellent choice for integrated weed management programmes across a wide range of public and private spaces.
