Wet weather has delayed wheat planting in many areas of the state. Generally, the best time to plant wheat is the 10-day period starting the day after the fly-free-safe date. When wheat is planted more than 10-days after the fly-free-safe date, there is an increased chance of reduced fall growth and reduced winter hardiness. The effect of planting date on wheat yield is shown in Figure 6-2 of the Ohio Agronomy Guide.
As cold weather approaches this week, livestock owners need to keep in mind the few forage species that can be extremely toxic soon after a frost. Several species contain compounds called cyanogenic glucosides that are converted quickly to prussic acid (i.e. hydrogen cyanide) in freeze-damaged plant tissues. A few legumes species have an increased risk of causing bloat when grazed after a frost. Each of these risks is discussed in this article along with precautions to avoid them.
Leaving corn to dry in the field exposes a crop to unfavorable weather conditions, as well as wildlife damage. A crop with weak plant integrity is more vulnerable to yield losses from stalk lodging and ear drop when weathering conditions occur. Additional losses may occur when ear rots reduce grain quality and can lead to significant dockage when the grain is marketed. Some ear rots produce mycotoxins, which may cause major health problems if fed to livestock.
