I placed an order with my local FS supply (Division of Growmark) for PBI/Gordons Q4, because I wanted to try it. When I came to pick up my order they told me that Quincept was just as good and was $20.00 a gallon less expensive. It does not have the 0.69% sulfentrazone Q4 has, so it's not really a 4 way herbicide, but all other AI ingredient in Quincept are the same except in higher percentages. I liked the price so I took it. FYI - I went to NuFarm's website and was quite impressed with the array of products. I would like to hear from anyone that has used this product. I will share my experiences with Quincept on my test plots.
