split stem

I made a minor crack/tear in one of my stems during super cropping (flowering is starting or about to start outdoors). Will spraying a diluted cold-pressed neem oil solution onto the wound and surrounding healthy foliage help prevent fungal infections and other problems or? I did this earlier...

Here's my current injury, will see how it goes plant will end up being moved too big final coco air pot soon, I'm hoping this branch holds on and thrives dripped honey on it. I feel like painting it with glue but I'm just going too leave it and see how it goes
