Sulfur and oil at this stage?

[saddlebronze]

Was wondering if it would still be safe to use Sulfur and horticultural oil at this stage? I am at anywhere from bud break to 4 inches and as I understand it since the temperature is low I don't have risk of sulfur damage at this point. I want to get ahead of the downy and powdery mildew now that it has begun to rain. Varieties in the signature. Thanks.

Check the label, I believe that the two cannot be used together without injury to the plant. Try something like penncozeb for the downey which can be used with oil and switch off to something like Captan around the second week in July for our area. Captan cannot be used with oil either so you will have to go to something like Nutrol or one of the strobies.
