It's one way to get rid of grubs!

An old adage recommended planting three seeds in every hill of corn.  The reason - "one for the grub, one for the crow, and one to grow."

Today grub damage to row crops is very low.  Grubs are the immature forms of May beetles.  The beetles lay their eggs in the soil of sod pastures or grassy areas in other crops.  Newly hatched grubs feed on plant roots for one to three years before emerging as adults.

Grubs become a problem when corn follows sod in the crop rotation.  Grubs then feed on corn plants and reduce the stand.  Because very little corn is planted following sod today, grub problems are very minor.

When it comes to grubs in corn, it's just not like it was in the good ol' days.  Thank goodness!
