Group 29 Fungicide
For resistance management purposes, please note that Allegro contains fluazinam, a Group 29 fungicide, which is considered to have a low risk of resistance development. However, as a general principle, it is recommended not to rely exclusively on the same product for pest control. To prolong effectiveness of this product, consult the label for resistance management strategies.
Allegro has a multi-site mode of action making development of resistant fungal strains extremely unlikely. This product is an excellent rotation partner for single-site mode of action products like Quadris® fungicide.
