Product Detail

Barbarian XL is a professional strength herbicide suitable for all types of annual and perennial grass and broad-leaved weed spraying or management of large areas.

Key Points:

  • Large 20L pack containing profession strength glyphosate (360g/l) for use in a wide variety of agriculture, horticulture, forestry and amenity situations.
  • Approved for use in knapsacks and boom sprayers.
  • Ideal for non-cropped areas such as roadsides, paths, hard surfaces and along fences and walls. Great for cleaning up weedy ground prior to planting or sowing plants and vegetables. Barbarian weed killer is a natural choice for total weed control on industrial sites and waste ground.

Barbarian XL is absorbed by the weed foliage and translocated to the growing points in the roots and to the underground rhizomes/stolons of perennial weeds. Best results are obtained from applications made under good growing conditions (adequate soil moisture and warm/humid conditions), when the weeds are actively growing and at the recommended growth stages for treatment.

* Always follow the Aftercare advice


Boom sprayer application rates vary from 1.5Lt/ha for cotyledon weeds up to 10Lt/ha for forestry use. Typically a 20L pack with cover 40,000m2 or 10 acres.

20L per 40000m²

After applying Barbarian XL 360 Full-Strength Glyphosate Weed Killer, avoid disturbing the treated area to allow the product to work effectively. Monitor the site over the next few weeks and only re‑treat if fresh growth appears.

Glyphosate is strongly adsorbed onto the soil particles and becomes practically immobilised within the soil. As a result, the weedkiller is subsequently broken down by microbial activity. New crops can be sown or planted at very short intervals after application.

Rinse application equipment thoroughly with a suitable tank cleaner and dispose of washings safely on treated ground. Keep pets and people away from the area until foliage has dried.

Orders placed by 1pm Monday to Friday are typically delivered within 3 to 5 working days (express delivery 1 to 2 days).
