Tenn Valley | As a Ciba- Geigy product development rep in the early '90's, I worked on Dual as a post herbicide. The only concern that we had was with Dual giving pre control only, how much product would hit the ground. What I remember about this project was the Dual would wash off plants pretty easily & it was important to get a rain after application. Since we started using pre herbicides back in the '60's the performance has always depended on getting a rain t o get them activated. | |
