spray for apple scab

Asked May 4, 2018, 10:52 AM EDT

I am not sure at what stage to begin spraying. Advice is when first green leaf tips emerge. Right now my tree is just beginning to "pop out" with reddish buds but upon inspection there is green also. Do I wait until the tree flowers, petals drop, or start now?
