It would be a shame to waste such a good crop of borers!

Don't depend on fall tillage or stalk chopping to reduce next year's corn borer problem.

Stalk destruction reduces the number of corn borer larvae that survive the winter in that field.  Larvae exposed outside the stalk are more likely to freeze or be eaten by birds.  Fall plowing also reduces the number of moths next spring.  Moths can't get out of the soil.

However, unless all farmers in an area follow these practices it's not likely to reduce the potential damage next year.  Winter temperatures and the weather during corn borer flights next June are more important.  Unless you can persuade your neighbors to keep "their" corn borer moths home next spring, damage can show up in fields that were disked, chopped, or plowed.

Remember, high corn borer infestations this year may not mean problems next year.  It's a little like the weather.  We'll just have to wait and see.
