Subdue MAXX Fungicide would have a 3-5 year shelf life if stored at room temperature with no extreme heat or cold, and no moisture got into the bottle.
Here are a few tips for getting rid of Pythium Blight:
Per the product label of Subdue Maxx Fungicide: You would use 0.50 – 1.0 fl oz per 1,000 sq ft in 1-5 gallons of water. The amount of water is not set as it is just the carrier and will be however much it takes you to cover that area. For best efficacy, 1/2 inch irrigation or rainfall is required within 24 hours after application. Within the rate range given for turf, use the lower rate for the shortest interval listed and the higher specifi ed rate for the longest interval. Under severe disease conditions, use the specifi ed highest rate and shortest interval. Please refer to the product label for complete instructions though depending the target disease you want to prevent.
Subdue MAXX Fungicide is not labled for a soil treatment when treating for phytophthora. Per the product label it should be applied as a foliar treatment only. Also this would not be a product that we would recommend for that either as you would have to use such a miniscule amount when treating hedges as the label states to use it in 100 gallons of water. To be able to break that down would not be worth using.
You could use Monterey Agri-Fos Fungicide. It is labeled for a soil drench at a rate of 2 to 4 tsp per gallon of water, and you would apply 1 gallon per sq yard. Follow the application with irrigation to get the product down to the roots of the plant. You can do repeat applications at 14-21 day intervals.
While Subdue Maxx Fungicide is labeled for numerous ornamental plants, it does not specifically list ferns as a tolerant plant. There are many plants the product has not been tested on to know the outcome, so for this reason we recommend contacting the manufacturer, Syngenta, at 1-866-796-4368 for more information regarding using it on ferns.

Subdue Maxx Fungicide can be applied as a preventative treatment against downy mildew in St. Augustine grass, and for Pythium blight and yellow tuft in bluegrass, according to the product label. For preventative applications, apply at 0.50 – 1.0 fl oz per 1,000 sq ft as a foliar application to established turf in 1-5 gallons of water. Re-treat at 10- to 21- day intervals based on level of disease conditions.
The use rate of Subdue Maxx Fungicide will completely depend on the type of disease you are treating for, and the type of application you are making. You should refer to the product label, which provides rates specific to disease and treatment type, and use as directed.

However, proper management practices can significantly reduce problems that may possibly occur. Generally, avoiding tree stress and maintaining an overall healthy tree is the best way of avoiding the canker.
