Dhol,
PPE changes sound fine.
Apples: Mancozeb is almost never used by Colorado growers -- the primary disease targets don't occur in the primary apple producing area of the state.
Grapes: Mancozeb is not used by Colorado grape growers-- the primary disease targets are rarely encountered in our grape production areas of the state.
Potatoes and Sugar Beets: There is no hand harvesting of potatoes and sugar beets in Colorado and Wyoming. The maximum feasible REI is 48 hrs, but 24 is preferable. Hand weeding, mechanical cultivation, and irrigation all need to be done following an application
Cucurbits: The maximum feasible REI is 48 hrs, but preferable 24. Hand weeding, mechanical cultivation, and irrigation all need to be done following an application
Let me know if you have further questions.
