Bonide Mancozeb Flowable with Zinc Concentrate is not labeled for phomopsis blight on a juniper shrub.
Propiconazole 14.3, is labeled for juniper phomopsis blight and a few other blights on ornamental plants. For phomopsis blight, make the first application as soon as the junipers start to grow, and repeat the applications every 14-21 days during periods of active growth.
