Box blight is a debilitating disease affecting the leaves and stems of box trees. Leaves turn brown and fall leading to bare patches while the stems develop black streaks and are prone to die back.

The condition is caused by infection by two often coexisting fungal species - Cylindrocladium buxicola (syn. Calonectria pseudonaviculata) and  Pseudonectria buxi. Both species are quite host specific with P.Buxi only affecting box.

No chemical control is effective against box blight bit improvements can be made by cultural means and by improving the health of the affected subjects' growing media.

The whole subject is explored in detail in a new publication by industry expert Pius Floris entitled the PHC Box Programme.  The disease is described fully and the use of a number of PHC products are highlighted that will help prevent and reduce the severity of blight attacks.  These include Biovin, Natural Green and Healthy Start Tablets.
