Pecan Tree Lawnmower Injury?

[Canyon Angler]

Hey all,

I have a young mahan pecan tree that I whacked w/ lawnmower and knocked bark off. (See photos.) I cut away the flap and am leaving it alone, but should I spray it with anything? I have sowbugs already going under the loose bark.

I have borax, Captan and Immunox anti-fungals; sevin, malathion, dursban; if needed.

Injury is on the WNW side of the tree, if that matters. Also, I took off a 1" dia branch straight above the injury (it was ready to go, anyway) to maybe lessen the water need on that side of the tree.

Is there anything else I should do, besides not hit it again? My hunch is that you'll say to just leave it alone and keep an eye on it, but wanted to check.

Thanks for any help.

Yep, leave it alone, if you must do something expose the root flare.
