When nematodes are suspected, soil and root samples must be analyzed to confirm the problem. 1100 gives detailed information on how to collect and ship soil samples for nematode analysis. The use of crop rotations or nematicides will be of little value for corn already planted. However, an awareness of corn nematode problems is essential for planning control strategies for the next growing season. For planted corn, try to maintain optimum growing conditions.
Nematode damage is greater on plants stressed by other factors.
Controlling other diseases and insects also reduces plant stress. For more information on corn nematodes, see Report on Plant Diseases Nos.
