Kerb Flo Residual Weed Killer 5L

Kerb® Flo is a residual herbicide that can be used as a pre or post-emergence weed killer in forestry and amenity plantings. It is predominantly used to kill grass weeds, but can also control troublesome weeds such as chickweed, cleavers, bindweed, fat hen, and will offer some control against horsetail.

Kerb® Flo can be used on ornamental shrubs, roses and is also widely used near trees and hedges. As it is mobile in the soil, it is important to apply it in cooler conditions (the soil temperature being cooler than 8 degrees) and when there is plenty of moisture. This best time for this is usually between November & January.

We have this product available as a spreadable granule which can be easier to apply. If this interests you take a look at Gem Granules.

If you want to increase the spectrum of weeds which Kerb Flo will control, mix 42ml Kerb Flo + 5ml Flexidor per 5L of water. This mix will now control mayweed, poppy, nettle, speedwell & buttercup.

It is important that you only apply one dose of Kerb Flo per year. For a full list of controllable weeds and the tolerant lists of Trees & Shrubs, please download the product label.

For a cheaper alternative, look at Propyz.
