Laurel Disease (2)

Asked October 5, 2013, 2:25 PM EDT

I have both Prunus Otto Luyken and Skip Laurel and they have some disease that is causing leaves and branches to wither and die or to cause "holes" to appear in the leaves. See pictures. (Note since I can only send one picture at a time I will repeat this request four separate times.) Is there a insecticide or/of fungicide, etc. that I can use to resolve the problems?
