Floppy corn syndrome is a root development issue that can occur between the V4 to V8 growth stages. This syndrome results in plants “flopping” or tipping over for a period of time and may lead to yield loss if the plants don’t recover. Interestingly, the plant usually shows visual signs before the physical tipping of the plants.
Corn experiences this syndrome as a direct result of poor nodal root development. Poor nodal root development can be caused by:
Rain! Getting moisture to the plants is the main way we can help alleviate the condition. If irrigation is available, it can be used as a tool for moisture relief. Otherwise, decent rainfall is needed. Some farmers have had success with row cultivation as this field pass tosses soil over the rows and conceals moisture over the nodal roots to aid the effects of shallow planting.
