High Winds Snap Susceptible Corn Stalks
Aug 01, 2010
Question: I’ve got some stalk breakage in my corn because of storms that rolled through here last week. This isn’t a problem I normally see. Any suggestions?
Answer: I’m not sure where you’re located, but since this problem isn’t something you normally see, I’m going to guess you’re somewhere east of Illinois? This issue, called green snap, is fairly common in those states that experience thunderstorms containing high winds. Corn that is in the pre-tasseling stage, when it’s rapidly growing, seems most vulnerable to strong winds no matter where you’re located. Also, some hybrids are more affected by high winds than others. If yield loss is significant—and you’ll know for sure at harvest—ask your seed provider about other hybrid options for 2011. Another thought: using growth regulator herbicides like 2,4-D late in the season or when temperatures are high have also been associated with snapped stalks. Review your agronomic practices from this year and jot down some notes to refer to so you can make adjustments, if need be, next season.
