Foliar vs. basal bark application?

[hayray]

Want to use some Crossbow to control autumn olive on some fence rows and pasture. Label states that basal bark treatment for dormant application using a whole lot of diesel. Concerns is that diesel seems to be expensive, and probably kill grass also, and is it easier to in labor to spray basal bark if it is thick and hard to get to, also on basal bark do you need to cover the whole circumfrance of the trunck, or just do a foliar applicaton. The foliar rate is using water and lower %v/v. On the foliar applicaiton how much leaf do you need, can this be applied in partial bud stage or bud stage if complete coverage? Have a guy with a ATV and sprayer that will do the spraying since I am putting in some food plots for him. This area to spray is thick, pretty inaccesible on a 130 acre new lease so I don't have time to cut everything by hand right now. Any advice would be appreciated, Thanks in advance.

For anything over an inch in diameter, if possible I prefer the basal treatment. The band has to be all the way around, I prefer about a 6 inch wide band. With basal you can better select what you're actaully spraying unless you want t o kill everything in the area. The diesel won;t kill the grass for the simple reason that you don;t spray any on the grass. Make the band a foot or more above the ground.

Thats is beginning to sound like as much labor as cutting. I am now wondering if it would be better to cut, and then treat cut stump or sprouts. Can this be done later with a broadcast spray and boomless nozzles?

Don't know. When I cut and spray I use the basal spray on the cut stump. I doubt the foliar spary mixture will work after the things are cut unless you wait for them to resprout and get some grwoth on them

I don't know about Crossbow, but have had good luck using Remedy in a basal bark treatment. Mix 25% Remedy, 10% penetrating surfactant like Cide-Kick II and 65% diesel. The Cide-Kick helps the mix wrap around the trunks. Works really well on honey locust, mesquite and huisache.

Here is a recipe for 3 gallon mix for back pack sprayer
3/4 gal. Remedy
38 ozs. Cide-Kick II
1.95 gals diesel

Open noozle to shoot a straight stream. Pump up about half pressure.

I would question the cutting and waiting to folar spray resprouts. Might not be enough folage to transfer enough to the root to kill it.

I agree. The plant goes into some sort of protectin mode and sprouts are hard to kill. I've been told you should wait a couple of years to spray sprouts to get good kill so you really havent' done anything. I like the basal spray too. If the canopy is too thick to get to the stems you might consider chemically defoliating one side of the hedge and once its defoliated hit it with the basal treatment.
