More about Shot Hole Borer (PSHB)
PSHB is a tiny borer beetle that attacks live wood. It comes with a fungus that kills the tree. There are currently over two hundred species of trees in Johannesburg under attack and over 20% of the trees in Johannesburg are already sick or dead!
Trees and shrubs need to be sprayed with a fungicide and surfactant every year. The sooner a tree is treated, the better the chances of survival. Preventative treatment is highly recommended. Very valuable trees should be given injections every year until a better solution is found. Gets pricey if you have multiple sick trees.
