Dagana,
Bhutan 
when is the best time to spray 2year old grafted walnut plants with Bordeaux mixture to control blight and die back disease, here the altitude is at the range of 1500-1700masl?
thanks

Blight comes in with the onset of wet and warm weather so I would spray whenever that time is where you live.
