Very Effective
By Tom on 08/21/2015
I have used Princep in every form available for over 25 years because it works and the product I bought here is equally effective. Great for parking lot cracks, fence lines and areas where no growth is wanted. Using the highest labeled rate works fine in these places.

Princep Post emergent Qualities
By Bill on 12/09/2019
Put down Princep about 3 weeks ago and have had surprisingly good results with post ermget knock down of annual bluegrass as well as some clovers and Parsley - Piert. Will do a follow up at the start of spring for full performance.

FOLLOW INSTRUCTIONS! It will work as claimed
By Cobia on 07/14/2022
I think most people who don't think it works do not follow the instructions. Three things MUST be done for successful results. 1. Application rate designed for square footage (area) of treated areas. 2. TIME OF APPLICATION! Most important. Do not expect this product to work after you have a forest of weeds growing in your driveway. This product is designed to PREVENT emergence of broad leaf, and with higher concentrations upon application, most any kind of plant you don't want growing in your parking lot, driveway, rock garden etc. etc. 3. Also VERY important. You have to apply this product, at proper concentrations, at the proper time of year, and make sure you also have at least 1/4" - 1/2" rainfall in the next two or three days, and if not, water it yourself. Read and follow instructions..... I love this product, but I know how much, what time of year, and how to "put it to bed" properly after I followed 1 & 2 above.

Great product

I have used this for many years. Weather is the biggest problem . To much rain or to little will greatly affect how good it works. I just wish punture vine was one of the plants it would suppress. It's not a weed killer. If weeds are growing they will need to be hit with 24D or Roundup to kill them.
