TreeDimension's right on it again...... I thought about mentioning it but had to go back to work.

Dilute the fertilizer (if that's the cause for the burn) by flooding the tree. Dilution works well for all kinds of chemical mishaps. Even when an herbicide is causing damage. Water's cheap and the easiest approach - you can flood an herbicide damaged tree and significantly dilute the problematic chemical - be it fertilizer, herbicide, etc. - assuming you're trying to dilute a water soluble product.

With wind burn, it's also usually related to dry conditions - wind burn is dessication - an extreme drying,

For petroleum based problems such as a diesel fuel spill, you go a different route.
