 However, green soybean stems make harvesting a little more challenging. If you don't like green stems, there's one easy solution. Don't use Headline or any of the strobilurin fungicides. If you've been using Veltima, 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 top-guard.
