Protection from caliche dust
Is there a product I can coat leaves of trees and plants with that will protect them from caliche dust? The oil companies are here and big trucks are throwing up serious dust (toxic) killing my plants & trees. I've lost 11 fruit trees, all my blackberries, etc. Rinsing them off does little good with trucks running 24/7. Dust control is mandated by EPA but I've been stuck in bureaucratic BS for months with no action, meanwhile losing my groceries. Any help on this is much appreciated.
