Fusarium Head Blight (Scab) of Wheat: Things to Consider When Harvesting

By:  Darcy Telenko, Purdue University

Wheat harvest has begun in Southern Indiana. Fusarium head blight (FHB) or scab is one of the most important diseases of wheat and most challenging to prevent. In addition, FHB infection can cause the production of a mycotoxin called deoxynivalenol (DON or vomitoxin).

Wet Weather and Soybean Stand

By:  Laura Lindsey and Alexander Lindsey, Ohio State University

Saturated soils after soybean planting can cause uneven emergence and stand reductions of varying extent depending on the stage of the soybean plant and other environmental factors including temperature and duration of saturated conditions. Additionally, increased disease incidence may further reduce plant stand.Flooded soybean field Continue reading

I have been getting many questions (and theories) about the how the wet spring will impact insects. My thoughts are below, divided by insect. Continue reading

You May Not Like the Rain, but Water-Molds Do

By:  Stephanie Karhoff, Ohio State University

Late-seson field symptoms of Phytophthora root and stem rot on a susceptible soybean variety.

A rare appearance from the sun allowed farmers in Northwestern Ohio to progress with soybean planting, but with more rain in the forecast (see the most recent weather outlook in the C.O.R.N. newsletter here), there is concern that early-season seedling diseases may develop.

The two main diseases of concern are Phytophthora root and stem rot and Pythium seed and root rot. Continue reading

Feed Prices in 2019

By:  Brenda Boetel, University of Wisconsin-River Falls

The USDA Crop Progress report released June 3, 2019 showed that as of the week ending June 2, 2019 only 67% of corn has been planted, compared to 96% in 2018. The July, September and December 2019 CME corn futures market contracts have increased an average of $0.59 since May 1. The average May change over the last 5 years has been a decrease of $0.11. Given the significant decrease in plantings and the percentage of corn that has been planted late, corn price may continue to increase. While the trade concerns with Mexico are the bearish indicators the decrease in acres will likely have a greater impact. Continue reading
