View our brand NEW and EXCLUSIVE Marestail / Horsetail killer Diamond
Pearl is a soluble concentrate formulation containing 150 g/l (13.52% w/w) glufosinate-ammonium. It is a fast acting desiccant herbicide used for controlling many grasses & broadleaved weeds, including troublesome weeds such as Horse-tail. Pearl can be used around the following areas; Fence lines, Natural surfaces not intended to bear vegetation, Permeable surfaces overlaying soils, Hard surfaces & Managed amenity turf for line-marking preparation.
Although Pearl is mainly a contact herbicide, there is also some translaminar movement within the plant (moving around the leaf). This makes it a safer alternative to glyphosate when spraying near wanted vegetation. Stems of trees & shrubs are largely un-affected by a treatment of Pearl, although care should be taken as some speckling may occur. Effects of Pearl™ can be seen within 48 hours making it an ideal total herbicide choice.
Pearl is available exclusively to Agrigem and also is available in a smaller bottle as Pearl 500ml. Pearl is an alternative brand to third party brands such as Whippet, Harvest®, Finale® 150 & Kurtail Gold®
On large or tough weeds two treatments may be needed, the first to kill the top growth, and the second to kill the stems or any lower leaves, the interval between treatments is usually within 14 days. For best results, we would also recommend the use of a water conditioner & herbicide enhancer which is called Activate-g
- If you want to control grass around trees, then try a graminicide called Falcon.
- For best results use with a fine-medium nozzle, this ensures good coverage over weeds.
- Mix in with Blue Dye to ensure no areas are missed.
