Saved by the Scouts: June 18-22, 2018
“Saved by the Scouts” is our weekly crop report, highlighting the observations of our crop scouts. The scouts saw strong crop growth and some Japanese beetles this week. Tune in to our blog or social media each week to see the latest crop conditions for our territory. We are excited to see this growing season progress and hope you find the information to be beneficial.
Staging:
Corn is currently in stages V8-V11. Meanwhile, soybeans vary across the territory, with the most developed fields in stages V8-R1.
Weeds:
There is little weed pressure in corn, and in soybeans, weeds are responding well to herbicide treatment for the most part. There’s been a large amount of volunteer corn, giant ragweed, marestail, and waterhemp this season. Keep an eye on these weeds, as control becomes more difficult with increased growth.
Rainfall:
While our growing season started off dry, it’s been nice to see good rainfall this week for some areas of our territory.
Japanese beetles:
Adult Japanese beetles have made a strong appearance, as anticipated with the high number of white grubs earlier this season. According to Iowa State Extension and Outreach, adult Japanese beetles complete development in 1,030 growing degree days, which our territory recently met. They will continue to emerge until we reach 2,150 growing degree days, so continue the watch for Japanese beetles in both corn and soybeans. For more information, check out our video on Japanese beetles, and contact your Stutsman Agronomist if insect pressure increases.
Up Next:
Corn is nearing tassle, which means fungicide application season is coming. Our growing season thus far has been warm and humid, which is the ideal environment for disease to develop. Keep an eye on your corn fields for signs of disease and be ready to consider fungicide treatment.
Thanks for tuning in to this week’s edition of Saved by the Scouts. If you have questions or concerns, reach out to your Stutsman Agronomist.
