Hexazinone (Velpar) injury
Eric Hanson, Horticulture
The risk of hexazinone injury is relative high. Excessive rates result in irregular yellow patches on leaves, which later turn dark brown and die. Affected areas are not confined to certain parts of the leaves or consistently shaped. Darkening along some leaf veins is sometimes seen. In severe cases, bushes may drop nearly all leaves.
Bushes are typically dead the following spring.
Velpar injury symptoms usually appear in the middle of the summer. Leaves may eventually fall off.
