Propyz is a residual herbicide which 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.

Propyz 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 the cooler conditions when there is plenty of moisture and the soil temperature is cooler than 8 degrees. This is usually between Oct & Feb.

We also have this product available as a spreadable granule. Why not look at Gemstone Granules

If you want to increase the spectrum of weeds which Cohort will control, mix 42ml Propyz + 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 Propyz per year. For a full list of controllable weeds and the tolerant lists of Trees & Shrubs, please download the product label.

Propyz is an alternative brand to third party brands such as Cohort, Prova & Kerb®Flo. This product is also available in a larger pack size called Propyz 5L
