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. The purchaser or end users are responsible for ensuring that Barrier H is used in line with industry approved Codes of Practice. All operators must be trained and certificated to apply Barrier H. By proceeding with your purchase, you are confirming that you hold the the necessary Certificate.

Licence: Barrier H is the world's first herbicide made using only natural plant derivatives from sustainable resources - licensed on the 14th April 2000. MAPP no. 17145

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.

Endorsements: Barrier H was awarded a Major Commendation under the Business Commitment for the Enviroment Awards 2002. 'Languard have been using Barrier H as part of our ragwort control programmes for several years. It is a highly effective tool in the campaign against ragwort, and we shall continue using and recommending it' LanGuard Ltd., Specialist Weed Management for Highways and County Councils (2008) 'By far and away the best Ragwort treatment I have come across. Safe to both operator and environment and totally effective' Johnny Peter-Hoblyn, Stud Manager, Shadwell Estate Company (2002). 'The results are just as good as you predicted and the Ragwort seems to be killed almost overnight' Michael Elwick, Centre Manager, ILPH (2000) I would just like to say that your Barrier H has been an excellent product in controlling the ragwort within the Army ranges. It works extremely quickly and the applicators are easy to use. There is no doubt that we will be using Barrier H in the future on this 7,500 acre MOD estate. - Major M H Burgess, ARMY Range Control, Lulworth Camp, Wareham, Dorset. I used Barrier H during the trial period at Roudham Stud. In both damp and dry weather there was the same effect - instant kill within several hours. This year there is no sign of regrowth. Tim Phillips, Roudham Stud, Roudham, Norfolk.
An amazing cure, to a very big ragwort problem. I have 87 acres across the Salisbury plains, up and down dale. For 9 years we have tried to get rid of this plant, but every year it comes back with force. For the first year using Barrier H, the plains have not been a blaze of yellow, from the dreaded Ragwort. As we keep a large number of horses grazing on the plains, it has always been very worrying for us and it is nice to know there is little of the plant left, and very reassuring to know, if it does come back, we will be ready with the Barrier H Spray - Lesley Miles, White Horse Equestrian Centre, Westbury, Wilts. I felt I must write and congratulate you on the Barrier H ragwort spray; you have saved me from insanity! The first summer following the purchase of my property I found to my horror my 3 acres looking like a carpet of yellow. The first year I removed 50 bags, the second 40, I broke 5 trowels and it nearly broke me. Then I saw an article about Barrier H. I used over two containers and was so amazed that I rang my friends and my mother! I even went and sprayed a sample area at a friends. THANKYOU its well worth the money, if your company had shares I would invest all my money in it, what an excellent product, congrats to you. Miss D Masters-Brown, Alpington, Norfolk. I am not in the habit of writing to companies, mainly due to lack of time. Suddenly, I find, I have time to ride everyday, paint gates, fences and do all sorts of things. I have been digging our ragwort on some land that has been set-aside for several years. I finally had to concede that the ragwort was getting the better of me and in desperation purchased Barrier H. Within hours of spraying, the ragwort has disappeared, leaving only small brown circles to mark its passing. It is almost like a miracle, I can hardly believe it! I shall sing the praises of this amazing product at all the horsey related gatherings that I attend. Mary Potter, BHS District Rep. For Romney Marsh, Kent. I am writing to you after using Barrier H, to let you know how impressed I was at the result. My wife and I walked the land numerous times before buying and saw no signs of ragwort. When spring came, the lower part of my field was covered, and we were horrified to think that we had put the horses in this kind of danger. We pulled as much as we could using a ragfork but even this was back-breaking and the roots didn't always come out, leaving the chance that the plants would come back. I surfed the net and stumbled across Barrier H and although rather sceptical we decided to give it a try. The weather was hot, it was ideal, and I managed to spot spray about a quarter of it. To my surprise by the time I had finished one container, I could see the first plants sprayed were dying. After 6 hours all the plants on that patch had collapsed and turned brown and within 3-4 days the plants had died back into the ground. It has now been 10 months and the patch treated with Barrier H shows no signs of re-growth. The beauty of Barrier H is that you do not have to spend a backbreaking weekend pulling ragwort when you could spray in a fraction of the time, and then you can spend time enjoying your horse knowing that Barrier H is fighting the battle for you. - Stephen Smith. Melksham, Wilts. I feel compelled to write and congratulate you on your ragwort spray. I have to admit that when I first read about your product I was very sceptical. I was at a loss to understand how a plant-derived spray could be effective and work to my benefit. The alternatives remained traditional toxic sprays, which are dangerous to horses and they don't seem to stop the plants returning on mass every year! Thus I cautiously ordered your Barrier H. It worked! I have found the advantages of using Barrier H numerous: the ragwort was killed very quickly, plants turned black and 24 hours withered and brown - Amazing to see! I was very impressed and would have no hesitation in recommending it as a very effective way to help in the fight against this horse killer!! - Miss S Shaw-Browne, Sherwood Forest Livery Stables, Mansfield, Notts. What an excellent product Barrier H is. We used it for the first time on our paddock and within a day the rosettes had wilted and two weeks later there was no sign of the plants at all. This is going to make our paddock maintenance so much easier as we can deal with the rosettes as they appear. Well done the team at Barrier for another excellent product. Jenny Haywood, Petersfield, Hampshire. I have worked tirelessly to eradicate this awful ragwort, that we inherited. I have, through blood, sweat and tears reduced it but every year it tries again to give us the run around. In despair we bought Barrier H with the knowledge that all of your products have been excellent for horse care, could they be as good for pasture care? Well, I think so. It really seems to be working and so far I'm extremely impressed.' Carolyn Cummings, Penrith, Cumbria.
