Then there are products containing potassium nitrate, which are often referred to as ‘stump removers’ not ‘stump killers’. Use potassium nitrate to speed up the decaying process of the stump, which makes it easier to remove . However, be aware that unlike glyphosate and triclopyr, potassium nitrate doesn’t aim to kill the roots of the tree. Apply a tough formulation of glyphosate (e.g. Roundup Ultra or Doff Weedout Extra ToughWeedkiller) to the foliage of the section you want to kill. Alternatively, cut canes to the ground and treat with a stump and root killercontaining glyphosate (e.g. Roundup Stump Killer, Doff Tree Stump & Tough Weedkiller orWestland Resolva ProTree Stump killer). Treat foliage of any regrowth appropriate personal protective equipment (PPE) – the operator must be trained and certificated to PA6 D

Bio-Chemical Mode of Action: Glyphosate belongs to the Inhibition of Enolpyruvyl Shikimate Phosphate Synthase (ESPS) group of herbicides. Glyphosate (e.g. SBM Job done General PurposeWeedkiller or Doff Advanced Concentrated Weedkiller)damage shows as leaf yellowing and browning, and shoots collapse on soft-stemmed plants. Roses and raspberries are particularly sensitive to glyphosate from July onwards. This causes stunting and leaf malformation, which may not be evident until the following season. Roses produce clusters of short, often pale shoots that resemble mini witches’ brooms. Residual weedkillers

Herbicides that contain glyphosate are generally the most effective against weeping willows. If you have a light infestation, a glyphosate-based herbicide like Roundup can be used to kill the willows. For a more severe infestation, a stronger glyphosate-based herbicide like Rodeo can be used. Other chemicals, such as potassium nitrate, can be found in different types of stump killer. Potassium nitrate will cause the wood of the stump to go soft which can make it easier to remove. However, if you don’t successfully remove all of the roots, they may continue living and spawn another tree. Ease of Application
