Brown rot: Many fungicide materials are effective on both brown rot and powdery mildew. Powdery mildew requires more sprays, and resistance is always a risk. Use the above products on brown rot, as they are effective, and mildew sprays are not effective at this stage of tree growth. Neither iprodione nor fenbuconazole are first-rate powdery mildew materials.


Abound 2.08F: Abound is extremely phytotoxic to certain apple varieties. See Application Directions, Resistance Management, and Attention information on label. Do not apply more than 2.88 quarts product per acre per season.

OSO 5%SC: Apply ever 7-10 days.

Ph-D: Apply every 7-10 days.

Procure 480SC: Do not apply more than 96 fl. oz. of PROCURE 480SC per acre per season.

Quadris Top: The azoxystrobin component of Quadris Top is extremely toxic to certain apple varieties.  See label for further information.

Rally 40WSP: Place into solution before adding oil. Make a second application at petal fall if disease-conducive weather occurs.

Topguard: Azoxystrobin component is very phytotoxic to some apple varieties (ie those with a gala heritage).

petroleum oil, summer: Do not apply to oil-sensitive varieties. Do not spray wet foliage. Do not spray when freezing temperatures are anticipated within 48 hours of an oil application, above 90° F (32° C) or when plants are under heat or moisture stress.

Vivando: Max 2 aplications per year (30.8 fl oz.). Do not apply with petroleum oils. Do not exceed 2 sequential applications.
