 Because if the plant is greener later in the season, I would hope that we would gain a little bit of yield from that. 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.
