I was wondring if anyonge out there has used a product called CONFRONT? The active ingredient is (clopyralid) for post emergent control. <p>I also saw an add for two pre-emergents named PORTRAIT and WIPEOUT. Has anyone had experience with these two products. I am looking for a pre-emergent with broadleaf weed control. Also, I dont want to get the vasoline out when I go to buy these type products.
