Not too bad, not too bad

July 4 came and went, and a few Iowa corn fields are now at VT, with tassels just emerging. Soybeans are also progressing well, and many fields are now reproductive (R1-R2). Although there are a few minor disease and insect issues around, including bacterial blight and brown spot on soybean and soybean aphids and corn rootworm beetle adult emergence, so far none of these has become a major problem.

Remember, soybean aphids do merit watching and will each year. Each week a new generation can be born, and populations can grow quickly. Remember soybean rust? Another week of no news is good news, but the disease is being found in a few more places in the South, so stay tuned.
