Spring Sampling OK for Two Corn Nematode Species
Plant-parasitic nematodes can damage corn. Each year, several instances of this are discovered in Iowa. More frequent cropping of corn following corn and less frequent use of soil-applied insecticides that might have provided some nematode control may result in more instances of nematode damage to corn this growing season. Also, nematodes are more damaging to corn (and other crops) during hot, dry conditions, so if a drought occurs in Iowa in 2008, damage to corn from nematode feeding may be more common.
