not as good as advertised

10 days ago
I applied this to the weeds on the east part of my backyard and at first they all became a dull green then after 2 days their color all came back and they all started growing again. Im afraid this was not a good product as my weeds are all growing again.

Great product

6 months ago
I’m a little confused at the negative reviews, I have personally use this product this weekend. I mixed up 6 ounces per gallon and was very pleased with the results. I applied the product to grass and weeds and within 24 hours it worked just fine. As an over-the-counter product, you cannot beat this.

Poor quality

This product isn’t worth a dime. A waste of time and money. Mixed it as specified and sprayed an area two times and still hasn’t killed nothing. Totally worthless

Is not fast acting and does not kill weeds

9 months ago
I bought this product twice, did not come close to what the product claims to do. I’ve used Diquat many times in the past and was pleased with the results. This formula just doesn’t do the job. Burns foliage but does not eradicate as described. I’ve added surfactant to it and that doesn’t help.
