Like all the new products using “natural” nonanoic acid’s, it doesn’t truly kill weeds. The majority of what’s in Bunnings now is the same. Just an acid that burns the exposed weeds but doesn’t actually kill the roots. Weeds are back again a week or two later. Huge waste of money. Also the product choakingly stinks once applied. I had to leave the property for 8 hours after applying it was that bad, not just the smell, but the chemical/acid burning smell in the air.

This was the second weed killing product I purchased from Bunnings. The first one did nothing, but this one certainly does the trick. You can see results within a couple of hours. I have since purchased the bigger container of this product. Highly recommend.

I purchased this spray just to test it as all other Seasol products we have used over the years have been really good. This is no exception, in fact I will use this for weed reduction from now on as it’s better than everything I have tried in the past.If you spray on a hot sunny day you will see dramatic results later the same day, never had that happen before.

This really works, weeds have started to die
I only picked this stuff up as all other options were sold out. I was dubious, it’s organic… but this stuff is liquid death. Weeds started wilting within 30 mins, 24 hours later and you can see on photos the exact place I ran out out of zero and switched to this organic agent orange… just wow
I was happy at first when within hours the weeds shriveled & died. But within a week the weeds came back healthier than ever! I am back to square one.
Recently purchased and am amazed at how effective it has been. I found that making sure the spray nozzle was held lower than the bottle when spraying aided with consistent delivery (similar principle to siphoning from a car right?). Also, smells like coconut oil.
Applied this product as I would have with regular glypho and was super impressed by the speed in which it worked. The weeds were brown and wilted within 48 hours and crumbling to dust after 7 days. It killed a wide range of weeds and grass types too!
The Seasol organic weedkiller is very effective. Unfortunately the method of application in the 3L container is not. The trigger spray mechanism leaks and loses solution from the cap. The nozzle has to be constantly adjusted to maintain a flow.
Couldn't get fluid to end of nozzle. Inspected hose- was broken just before handle. Removed broken piece and reinserted into handle. Still couldn't generate spray beyond 2 cm. Put into to another spray bottle. Very messy. Not sure if it works yet.

Seasol Earthcare 1L Organic Weedkiller
EarthCare Organic WeedKiller is a glyphosate-free herbicide. Its rapid, non-selective formula kills and controls weeds including: barnyard grass, camel melon, capeweed, chickweed, common storksbill, couch grass, clover, fat hen, giant brome grass, indian hedge mustard, lambs tongue, peppercress, potato weed, perennial ryegrass, sowthistle, stinking roger, whorled pigeon grass, algae, moss and lichen. It’s ideal to use in the garden, on driveways and paths, around buildings and as a spot spray in lawns. It works quickly to kill and control weeds, however, it must come into contact with the green part of the plant to work effectively. EarthCare Organic WeedKiller is an organic contact herbicide containing pelargonic acid (nonanoic acid), natural plant oils converted into a natural acid. Pelargonic acid occurs naturally in plants including geraniums. It acts on the plant foliage causing it to quickly dehydrate and collapse. Visible results are seen as browning and wilting, usually within hours of application. Non-residual and biodegradable, it breaks up rapidly in the soil, leaving no lasting residue. It is safe to use around edible produce as there is no withholding period when used as directed. Seasol EarthCare is proudly Australian Made and Owned.
