Ilderton, Ontario | basagran is contact only, and pursuit has residual, but isn't strong on ragweed (but it is on the label), especially if you have any pursuit resistance. As far as the foxtails, not sure, but I did have some reachback with grasses earlier this year with pursuit prowl. In our situation we didn't have rain prior to the weeds emerging. When the grasses were 2 leaves we got a rain to activate and the grasses then died. I would think that the rains should have activated with your rains. In another field I have already resprayed for ragweed where pursuit prowl was applied. In another I have resprayed for foxtail with pursuit prowl down. I have had good rains too. | |
