This was recommended by our arborist to treat Red Push trees suffering form Texas Root Rot. The tree is about 4 years old, still relatively small, and sits in soil covered in rock in about 4' x 4' space.
Unfortunately, there is no effective treatment once the infection is established; the best course of action is usually to remove the affected tree and prevent further spread by planting resistant varieties in the area, as the fungus is soil-borne and can infect other plants. While the Monterey Garden Phos Systemic Fungicide is not specifically labeled for Chinese Red Push Pistache trees, it does have labeling to control root rot on a variety of edible and ornamental plants and trees. In the tree section, it states to " Use 2 to 4 tsp. per gallon of water. Apply one gallon of solution per sq. yd. Follow application with irrigation. Application intervals: 14 to 21 days. Repeat as required"
