Diamond is a brand new product exclusive to Agrigem which offers excellent results on many tough annual and perennial weeds including horsetail. It is a soluble concentrate containing 160g/L 2,4-D + 240g/L glyphosate.

As well as treating weeds such as bindweed and ragwort, Diamond is one of the few products on the market that will successfully control horsetail. Previous products containing glufosinate-ammonium used to control this difficult weed are no longer permitted for sale in the U.K making Diamond the go to product following its launch in spring 2019.

Often seen in spring and summer, horsetail (otherwise known as marestail) is an extremely invasive perennial weed with deep roots. If left untreated horsetail will spread at a fast rate and crowd flower beds, borders, lawns and patios.

Diamond is approved for use on amenity vegetation, orchards, hard surfaces (railway ballast), and green cover not being used for crop production. After application the 2,4 - D will break down leaf tissue which enables the glyphosate to translocate around the plant far quicker and deeper. It will deliver total weed control to both grasses and broad-leaved weeds, controlling them swiftly and penetrating deeper into the root system than glyphosate alone. For increased results, mix with Activate-g 1L to penetrate waxy & hairy leaves.

This product is also available in a bigger pack size called Diamond 5L.
