Bayleton (triadimefon)
Bayleton is a systemic fungicide with protective, curative, and eradicant action, which is very effective for controlling apple powdery mildew and cedar apple rust. Bayleton should be first applied at the green-tip stage and continue applications at 7- to 14-day intervals or as needed until terminal growth stops. Bayleton is also recommended for the control of powdery mildew on pear. The first application should be made at the budburst stage and continue applications at 7- to 14-day intervals or as needed. Bayleton is recommended at 2 to 8 ounces per acre, depending on disease severity. If mildew is severe, other fungicides that are effective against mildew should be applied at the tight cluster bud stage and at first cover.
