 Veltema, Dilauro, Trivapro, or almost any soybean fungicide pre-mix, you've been spraying a strobilurin. One of the few pre-mixes that does not have a strobe is Lucento. What Lucento contains is a great triazole and an SDHI. The triazole is TopGuard, which we believe is the longest lasting, most systemic triazole, and the SDHI component is Bixofen, which is really good too. Lucento is also reasonably priced compared to many of the other fungicides, so it's one of our favorites.
