We recommend using concentrates such as Quadris Fungicide within 3-5 years of purchase and to store out of direct sunlight and extreme temperatures. You should use diluted solution within 24 hours.
Quadris Fungicide can be applied to apple trees, but can be photo toxic to certain varieties. Please review the label prior to application.
Quadris Flowable Fungicide is applied at 6.2 fl oz per acre in enough volume of water to cover the acre as directed (using a minimum of 10 gallons of water per acre).
