Destroy Ragwort in record time with Barrier H.

Designed as a spot spray treatment, it can be used ALL YEAR ROUND even in winter. Applied to flowerheads, it will stop the seeding process.

Licence: Barrier H is the world's first herbicide made using only natural plant derivatives from sustainable resources

Application: Apply in accordance with the instructions on the Container

Cost effectiveness: Barrier H will destroy ragwort at all stages of growth any time of year. It is more cost effective to treat when at small rosette stage. The stems of larger plants and flowering plants become thick and woody and so need more Barrier H. We advise people to cut, bale and burn/remove from site at the height of summer as it will take up too much product. Winter application is a good time to apply Barrier H because Ragwort is easily visible. Traditional weeds and grasses die back and Ragwort seedlings and re-growth from older plants appear. Ensure the whole plant is well wetted but not to the point of run off.

Exclusion From Grazing: After application, we recommend that animals are kept away from treated pasture for 2 weeks, or until the ragwort is completely dead and any debris (with more mature plants) has been removed. This is not because Barrier H is in any way harmful, but because the dying ragwort as it releases sugars becomes palatable and so possibly dangerous to animals. Remember the root is the last part of the plant to die, so be careful not to remove any dead tops too soon.

Cutting or Pulling: Time spent cutting or pulling may be wasted as it often results in encouraging the spread of Ragwort. Tiny pieces of root left behind can lead to the growth of bigger and stronger plants.

Flowering Ragwort: Barrier H can be applied to flowering Ragwort to stop seed setting but we still advise to cut, bale and burn/remove all that plant growth.

Spot Treatment: Barrier H comes in a 5L container with spray attachment and is used as a spot treatment for Ragwort. It is easy to apply holding the container handle in one hand and the spray gun in the other. One single squirt is sufficient to cover a tiny seedling. Users often prefer to use a knapsack sprayer with a longer lance.

Seeds: Ragwort Seeds can lay dormant in the soil for up to 20 years. Each plant can produce up to 150,000 seeds with a 70% germination rate.

Summer application: Late June, July and August are normally when Ragwort flowers. For every flowering Ragwort, there are around 10 small seedlings or rosettes close by which need to be treated before they too become large flowering plants.

Winter Ragwort: Autumn, Winter and Spring are when rosettes are most visible. Grasses die back and most other weeds die off leaving the bright green Ragwort easy to see and to treat. However, to achieve the very best results, Barrier H is best applied in dry conditions.
