Roundup Tree Stump & Root Killer MAPP13850 (contains Glyphosate)
Roundup Tree Stump and Root Killer is a non-selective, translocated weedkiller that is absorbed by leaves and freshly cut, woody surfaces and moves throughout the entire plant, above and below ground to control standing coniferous and deciduous trees, newly cut tree stumps, tree saplings, brambles, bracken, nettles, Japanese knotweed and other tough and woody weeds. It will also kill grasses and other weeds including deep rooted perennials. It is inactivated on contact with the soil and is then broken down by soil micro-organisms to allow replanting.
When to use: Apply as a foliar spray to weeds and saplings at any time when the weeds are actively growing and have adequate leaf area to absorb the spray. Freshly cut tree stumps and standing trees should be treated from November to March to avoid the period of active sap flow in spring / early summer. Avoid spraying when rain is imminent. Rain within 6 hours of spraying may reduce effectiveness so repeat treatment may be necessary. Avoid spraying in windy conditions as spray drift to lawns and other wanted plants will damage or destroy them. Avoid all other contact with cultivated plants. If cultivated plants are treated by mistake immediately and thoroughly wash off the weedkiller with ample water.
Where to use: Roundup Tree Stump and Root Killer controls annuals and most perennial weeds and trees around the garden and on areas not intended to bear vegetation such as hard surfaces, patios, drives, tarmac, path and gravel areas. Do not use on lawns or other wanted plants. Do not use under polythene or glass.
How to use: Although not a requirement, as good practice, we recommend wearing waterproof gloves and gardening footwear. Roundup Tree Stump and Root Killer - Tree Stump Dilutions: Deciduous trees – 10% solution in water (e. g. 100ml in 1 litre of water). Coniferous trees – 20% solution in water (e. g. 200ml in 1 litre of water). Areas not intended to bear vegetation such as hard surfaces, patios, drives, tarmac, paths and gravel areas apply 15ml per 1 litre (or 5 litres in a watering can) per 30m2. After application rinse the sprayer/watering can 3 times, pouring rinse water over bare ground. Triple rinse the empty bottle and poor rinse water over bare ground.
Freshly cut tree and shrub stumps – cut the tree or shrub stem close to the ground in November to March and thoroughly treat the cut surface of the stump as soon as possible after felling. Use a paint brush to apply the diluted Roundup Tree Stump and Root Killer on to the cut stump. Ensure the whole cut surface is saturated particularly around the edges and bark of the stump. Ensure the brush is thoroughly cleaned before and after use.
Standing Trees (Coniferous and Deciduous) – In November to March, use an axe to cut angled notches that completely penetrate the bark of standing trees. Cut at approximately knee height, one notch for trees up to 10cm in diameter and use two or three notches in trees over 10cm diameter. Using a ¾ or 1 inch standard paint brush apply 2ml (thorough wetting of the inside of the notch) per 10cm trunk diameter of neat Roundup Tree Stump and Root Killer to each cut. Do not treat in the period of active sap flow in the spring / early summer.
Japanese Knotweed – Apply as a foliar spot application using a 2% solution (20ml in 1 litre of water). For best results apply when the plant is flowering (usually August / September) but before autumn dieback. Good coverage is essential. Spray the underside as well as the upper surface of the leaves. Repeat treatment may be necessary if re-growth appears. If Japanese Knotweed is growing amongst wanted plants apply 10ml of a 20% (200ml Roundup Tree Stump and Root Killer in 1 litre of water) solution with water per stem using the following method: After mid August but before leaf fall, cut the stems of the plants approximately 200mm above the base of the cane and 40mm above a node. Rupture the central stem tissue with a screwdriver and apply 10ml of a 20% solution of Roundup Tree and Stump Killer into the hollow stem within 15 minutes of cutting using the 10ml disposable pipette supplied with the pack. Gently dispense pipette avoiding splash back. Stems must be larger than 8mm diameter.
Do not apply through, or store in, galvanised or unlined steel sprayers or watering cans. Weeds show effects within 2 – 4 weeks. Dead of dying weeds can be dug in or composted without harming future crops. Users should be aware that dead standing trees are a potential hazard and therefore should be felled before they fall over. Don not walk into treated areas until the product has dried on leaves to avoid transfer to lawns and other desired vegetation. Replanting and sowing: leave at least 7 days for the weedkiller to move to underground roots and shoots before digging or cultivating soil.
Deep rooted weeds (foliar application) – Roundup Tree Stump and Root Killer to be added to: Sprayer: 1 litre of water / Watering can: 5 litres of water. Tough perennial broadleaved weeds: bindweed, dandelion, docks, ground elder and thistles – 15ml, area to be treated 30m2, best time of year to treat dandelions, docks: April – October, best time of year to treat bindweed, ground elder, thistles: around the flowering time. Some tough weeds (e. g. horsetail, ground elder and Japanese knotweed) may need a repeat treatment if re-growth appears.
Brush weeds and saplings (foliar application) – Roundup Tree Stump and Root Killer to be added to Sprayer: 1 litre of water / Watering can: 5 litres of water. Brush weeds: brambles, nettles, horsetail and bracken – 20ml, area to be treated 30m2, best time of year to treat brambles, nettles, scrub: June – September, horsetail and bracken: July – August, fully grown nettles: cut back in early summer and treat re growth in September. Some tough weeds (e. g. horsetail, ground elder and Japanese knotweed) may need a repeat treatment if re-growth appears. Saplings – beech, sycamore, oak, hazel, willow and ash – 20ml, area to be treated 30m2, best time to treat: June – August before leaf senescence.
Guide: 1 litre is approximately 2 pints, 5 litres is approximately 1 gallon, the output of a watering can is about 5 times greater than that of a sprayer. The same amount of Roundup Tree Stump and Root Killer is required to treat 30m2 when diluted in 1 litre of water in a sprayer or in 5 litres of water in a watering can.
