A citrus fungicide that manages the damaging effects of citrus disease is a strong defense against threats like Greasy Spot. 

A proactive approach to fungicide management helps you stay one step ahead to protect your citrus leaves and prevent the costly impact of disease.    

Luna Flex is recommended to be used preventively as part of a full-season program with two to four foliar applications, but the recommended timing is between late May until late June—prior to bloom, before conditions occur that allow diseases to thrive if left untreated. Luna Flex excels in avoiding vulnerabilities and protecting your investment from the start.

Trials conducted in Waynesville, NC and Vero Beach, FL in 2021 by NC State University and an independent research organization, respectively. For head-to-head comparison, fungicides were applied as a full season program with five to seven applications. Please follow the label for rates and timings for commercial applications. Nonionic surfactant was used with all spray applications. Other fungicide applications in the programs were similar across all the treatments. Luna Flex @ 8 fl oz/A and Miravis Prime @ 11.4 fl oz/A treatments were not evaluated in Waynesville, NC trial. The severity of early blight was evaluated at regular intervals and data were used to calculate areas under the disease progress curve (AUDPC). Means within series followed by the same letter are not significantly different according to Fisher’s Protected LSD (P<0.05).
