Unfortunately, typically once the plant is impacted or showing signs of root rot disease, there is no cure or remediation to save the plant. It is recommended to immediately discard infected plants after a positive diagnosis is made and then discard unwanted plants at the end of the season. Disinfect all gardening tools, prep surfaces, as well as gloves and washing your hands when handling soil, clippings or matter from the infested plant to prevent spreading.
Regarding the use of Monterey Garden Phos Systemic Fungicide and since it is not labeled for this application treatment, the advised ornamental rate they provided would be the only thing to go by even though it is a broad range of 0.5 fl to 6 fl oz per 1 to 5 gallons. The low rate is most of the time for preventative applications and the higher rate is for high pest pressure.

The Monterey Garden Phos Systemic Fungicide is safe to be mixed with a surfactant such as Pentra-Bark and applied to red oaks and other trees. We unfortunately couldn't say how effective it would be on other species of Phytophthora since its not been labeled or tested for them. The application wouldn't harm the tree and usually some form of disease treatment would help. We would recommend potentially partnering with a company local to you to see if there are any other steps they suggest based on the current look and condition of your trees.

If doing a preventative fungicide treatment for pythium using Monterey Garden Phos Systemic Fungicide, you could rotate with Heritigae SC (Class 11) or Propiconozole 14.3 (Class 3) before disease conditions are present.
If Pythium has already is already established and present in the lawn, it is more difficult to control. Subdue MAXX Fungicide would be a better fungicide for active pythium. Re-treat at 7 to 14-day intervals if conditions remain favorable for disease.
There is no waiting period for overeseeding. Make sure you are not mowing the lawn while the turfgrass is wet as this spreads the spores on the mower blades, reduce thatch and improve drainage with core aeration, increase air circulation and reduce the amount of shade which will limit the amount of time of foliar, occasional deep watering of the lawn is better than frequent light watering, do not water at night.
Please view our Pythium Treatment Guide for more information and product recommendations.

Although we have found some conflicting information, the most recommended method and most effective way of preventing Phytophthora root rot disease is to provide good drainage and to practice good water management. Don't over irrigate the soil more than necessary and the beddings are in an area where the soil will tend to stay moist, consider planting trees and shrubs on mounds, especially in an area where you know Phytophthora is present. While Fungicides help, they recommend that you do not rely on fungicide applications alone to control root and crown rot diseases.
Please view this article by the University of California Extension on Phytophthora Root and Crown Rot in the Garden for more information and also, we would recommend contacting your local extension office and speak with the Master Gardener directly for fungicide rotation recommendations that have been studied and tested in your county.
