How to Manage Nematodes in Cotton

July 16, 2012 10:04 PM

The following information is a Web Extra from the pages of Farm Journal. It corresponds with the article "Knock Out Nematodes." You can find the article in Farm Journal's 2012 Seed Guide.

Steps for Developing a Nematode Management Program:

  • Sample field(s) to determine if nematodes are present; if so, establish population density levels. If NO species are detected, the strategy is to make sure none are introduced.
  • If nematodes are present, the strategy is to keep them from spreading to non-infested fields and to reduce population densities.
    • Effective management practices require knowing which field(s) is/are infested, genera present, and population densities.
    • Lance nematodes should be identified by specific species.
  • Develop a Nematode Management Program well in advance of planting.
    (For more information, see Nematode Soil Sampling).
  • Review analysis of soil samples taken last fall to identify nematode species, their locations, and their densities.
  • Review nematode control options -- cultural and chemical practices -- that are available or practical in your situation.
  • Design and follow a strategy that suits your special situation. Consider factors such as history of cropping patterns, soil types, single/multiple nematode species present, and weather anticipated.
