Phytophthora Management in Newly Planted Citrus Groves
8000
Presidio fungicide effectively controlled Phytophthora root rot when applied to a newly- planted orange grove. At the end of the two-year study, Presidio -treated trees had greater canopy area as a result of reduced damage to the trees’ root systems. Means followed by the same letters are not significantly different (P≤0.10). Source: University of California

How To Use New or Established Plantings
Spray directly on soil beneath canopy or apply through drip or micro-sprinkler irrigation Mix 3–4 fl oz of Presidio in 20 gallons of water. Apply up to 10 fl oz of finished solution uniformly around the base of each tree, directed at the root zone. If rainfall does not occur within 24 hours after application, irrigate with sufficient water to move product into the root zone (0.5–1 inch of water).

MRLs
The U.S. tolerance for the Presidio soil use pattern is 0.01 ppm. No international MRLs are needed because the U.S. soil use tolerance is at or below global defaults.
Other Important Information Do not make more than one application per year Do not apply more than 4 fl oz/A per application or per year If additional fungicide applications are required to maintain adequate control of disease, follow Presidio with a labeled fungicide with a different mode of action
