The miticide/fungicide Magister (Fenazaquin) has been labeled by Gowan on melons, fruiting vegetables, hops, legumes, and fruit trees. Only one application can be made per year, and applications should be made in at least 50 gallons per acre. It is a group 21A miticide, same mode of action group as the miticide Portal (Fenpyroximate) and the insecticide Torac (Tolfenpyrad). For resistance management, do not apply either product before or after applying Magister. It also has pollinator protection language on its label. Be sure to consult the label and the special pollinator language before making applications.
