My thought process is to spray this on the leaves just after they sprout while it is still tall and not spray directly on the ground - I would get more into the soil I guess if I cut first then sprayed when they sprout. May not make any difference I don't know if the active ingredients get into the soil via the root system of the dead plant. I'm not that technically savy with chemicals. I'll run over it with the bush hog soon as I get a kill. I should be able to get anything that subsequently sprouts with probably 2,4-D and Roundup as a second round of spraying early summer. 2,4-D does better IMO if the plant is actively growing.

Goatkiller, you need to wait until leaves are fully developed before spraying for best results. Spraying too early will result in poor control.

Also, mowing most any brush species down before spraying is not a good practice. You end up treating the resprouts which have less leaf area than if left alone. So basically you end up treating a small cluster of branches to control a fully mature root system. Again, results usually are not food. Just an fyi.

10-4 I'll wait to spray and understand that you want to spray first then mow. That's how I do all my spraying typically.

Good advice. Need lots of foliar contact to carry chemical to roots. Label specifically says do not mix with 24D. Also not a good idea to mix with gly as it can interrupt adsorption. Arsenal and most brush killers work best in late summer and fall. The floum (sap) translocates the chemicals down into the roots for complete kill. Spraying in the spring often just top kills and plant will resprout
