Mix this concentrated roundup accordingly to the specified dilution ratio in my sprayer backpack. 7 days later I started to notice the weeds turn yellow and eventually brown. Highly recommend this item for larger jobs as this 5L container will last a long time.

No good value here! 20L is $180. This equals to $456 for 20L.

Check the dosage - for me it was not strong enough.The booklet says for general home garden weeds the ratio is 10mL of Roundup for 1L of water. I have followed it and sprays all around the garden in a dry day.10 days later, the weeks are looking stronger than ever!I will try again doubling the dosage to see - my I am afraid I will damage everything else around it.

Had to use more per litre than recommended on Singapore Daisy. Effective on repeat spraying
Changed brands to Roundup. Spent 4 hours spraying and after a week, the weeds seem to be thriving well. Checked our mix and it was perfect. Not Happy!
Despite spraying in fine weather, dry conditions, and 10+ hours before the rain resumed, this bottle of roundup does not seem to have been effective as past batches. I've used roundup for years but not impressed with this batch.
Roundup herbicide although expensive works extremely well, just be careful of garden plants.
Glyphosate is a safe and brilliantly effective herbicide. My garden is better for its efficient capacity to kill unwanted plants - weeds!
Kills everything, as stated. But bad for the soil, so make sure you don't want to grow anything special there afterwards. Grass and weeds will still come back after a few months.
The best product of it's type on the market. Works every time.
