POWDERY MILDEW

WHEN WE SEE THE WHITE ON LEAVES, 
THE PM IS MOST ACTIVE.

RUBBING PM OF THE LEAF IS THE EASY WAY 
TO DETERMINE IF THE WHITE IS PM.

PM IS OFTEN MORE OF A PROBLEM IN JUST 
WARM WEATHER RATHER THAN WARM AND
 WET.  SO WE EXPECT MORE PM THIS NEXT WEEK.

IN SMALL INFESTATIONS, PRUNE;  IN LARGE
 INFESTATIONS, CHEMICAL CONTROLS MAY 
BE NECESSARY.
