Old Pathclear GREAT ! new Pathclear a total waste of time and money. No effect after several weeks and new weeds come through very quickly after application. Ridiculous price for a poor product. Should be withdrawn or reformulated so it works as well as it used to do. Avoid.
The new Pathclear is very inferior to the old much-appreciated product.a) Weeds are still alive after 10 days. The used to die after 2-3 daysb) The same size box covers a much smaller area - very sneaky!c) The instructions admit it is inferior. Old Pathclear was still effective if it rained after 10 mins. New Pathclear says it mustn't rain for 6 hours - and even then it still doesn't work!
Weedol & Roundup on the borders, Verdone on the lawn. That leaves the drive, patio and path without their own tailor-made chemical cure-all. This is where Pathclear comes in. Sitting alongside all the other weedkillers in B&Q was a dark blue box with a picture of a weed-free gravel drive and immaculate lawn with the label "Pathclear" in a big sunburst. "Weed-free paths, drives and patios" boasts the front of the box. "Fast acting. Long Lasting" it continues. Claiming that it could keep paths etc clear of weeds for up to 3 months at a time, it sounded like I could find a use for it somewhere so in the basket it went, to be put to the test alongside the Weedol, Roundup and Verdone (see opinions in the relevant sections). Opening the box revealed that, almost identically to Weedol, Pathclear comes in granular form, packed in individual sachets (5 in all). As with Weedol, the granules dissolve quicker if you use warm water and I strongly advise this or you will be waiting forever for the stuff to dissolve! Pathclear actually has a lot in common with Weedol, it contains both Diquat and Paraquat (as does Weedol) but has the added 'benefit' of simazine and amitrole. My guess is the latter two are what give it the 3 month staying power. According to the instructions, one sachet should be added per 4.5litres of water meaning I'd need two for my 9litre watering can. This should give me enough diluted weedkiller to treat 34sq metres (17sqm per diluted sachet)... it may not sound a lot but looking at where the weeds grow, it's usually only around the edges or in cracks in paving so 34sqm actually goes quite a way. Once I started 'watering' it became evident that I probably had more than enough to do what I wanted. Concentrating on where the weeds were growing and giving them a thorough soaking I had more than enough to do my drive, patio and the garden path. Now to sit back and see if it actually
works which, considering it contains the same stuff as Weedol, I had high hopes of. I am pleased to say that I was not to be disappointed. The claims of fast action were verified within 2 days. Weeds started to turn grey in much the same way as the Weedol treated weeds and after 4 - 5 days the majority were all but gone. Quite where the weeds actually go after this treatment is still a bit of a mystery, but I have yet to actually pull out any dead weeds. I suppose the decomposition must be extremely rapid once the chemicals have done their stuff. I did say that the majority had gone... there were still some tougher weeds (most notably clover) that were unaffected and needed digging out by hand. The real test was yet to come though. Would it really keep my drive free of the green menace for 3 months? No. Not on your nelly. After about a month or so, the green stuff started to reappear in exactly the same places I'd soaked to the bone with Pathclear only 4 weeks earlier. Had I done something wrong? I went back and re-read the instructions... Pathclear should be applied in Spring, I'd applied it in May. "Long Term effect will be reduced if used under hot/dry conditions". May was nice this year, but to reduce the efficacy from 3 months to barely 1 month? I think that's pretty poor. So that was it, I may as well have used Weedol for all the 'long lasting' effects it had. Maybe the weeds in this part of the world are particularly vigorous but I doubt it. Do I still use it? Nope. The original box still has 3 sachets left in it. During the same time I've gone through several boxes of Weedol/Roundup/Verdone etc. Pathclear was the only one I tried that didn't do what it claimed. Words of Warning. This stuff is sold for use ONLY on hard ground, my guess is if you use it on soil you'll not be able to grow anything in it for a fair old time. It's safe for pets & kids once it has dried but it
9;s NOT safe for fish/ponds. If you do use it, you're not supposed to use anything else (other than further doses of Pathclear) containing atrazine or simazine on that patch of land within a year. That's a MAFF requirement, not a marketing ploy.
