Application
Apply 4-6 fl oz/ of Tebuconazole at the earliest sign of infection (rust pustules developing) or when weather conditions are favorable for rust development.

Disease Control
For optimum rust control, the lowest labeled rate of a spray surfactant should be tank-mixed with Tebuconazole. Tebuconazole must have two to four hours of drying time on plant foliage for the active ingredient to move systemically into plant tissue before rain or irrigation occurs. After this period of time, Tebuconazole will be resistant to weathering.

Remarks:
For maximum disease control, labels recommend using lowest rate of nonionic surfactant. Apply at earliest sign of infection. Do not apply more than 16 fl oz per season or within 50 days of harvest. See labels for further information or spray scheduling.
