Cut stump treatments are also useful for managing invasive vines, such as Oriental bittersweet, which climb into the canopy and can be difficult to reach with foliar applications. If after three weeks the seeds fail to emerge, the seedlings or cuttings are distorted, show less growth than in the controls or exhibit fern-like growth in the suspect growing media, while control plants are normal, there are strong grounds to believe weedkiller residues are present.

The number required will vary depending on the species being treated. SBK Tree Stump Killer comes as a 250 ml concentrate, which states that it’s capable of treating up to eight stumps. However, large stumps will likely require repeat applications, so this number is reduced.

Cut Surface Treatments: This technique involves creating a pathway through the bark so that herbicide can be introduced into the plant's vascular tissue. Start by making a series of downward cuts around the circumference of the tree with an ax or hatchet, leaving the frill (cut section of bark) connected to the tree. Immediately apply the selected herbicide into the cuts. Avoid spring applications when sap flowing from the wound will prevent good absorption. Conventional vehicle mounted or handheld spray equipment - apply at a rate of 1.5-10 l/ha in 80-250 l/ha water using a medium or coarse spray quality nozzle. If you perform proper stump treatment with Roundup and do not spray surrounding plants directly then a Roundup application will leave nontarget plants and trees unharmed, while killing target plants down to the root. Is Tordon Safer than Roundup? Clearing out underbrush or removing woody shrubs and trees can leave unsightly stumps that must be removed before the area can be used for other purposes. Stump killers are designed to either kill a green stump that might otherwise send up shoots or decay an already dead stump, softening it and making it easy to remove. For those looking to use this type of product for the first time, some questions are to be expected. Q. Should I remove my tree stumps?

However, Grazon also kills other plants including grasses so be careful when using it near your garden or lawn. If you suspect a problem with a particular batch of peat-free or peat-reduced compost or manureit is possible to do a simple test for weedkiller residues.

Picloram: Picloram is a systemic herbicide that destroys woody-type plants. This herbicide is found in products designed to both kill and decompose the stump.

Tordon can kill surrounding trees in the area of application, even if the the tree was not directly exposed to the chemical spray. This is because Tordon enters the soil by penetrating the stump of the treated tree and spreading to the roots. Once there, it may “jump” from the treated tree’s roots to another tree’s roots. Herbicides applied at this time are also moved downward to roots during this process of translocation, enhancing the effectiveness of the application.
