Managing Nematodes in the Southeastern Coastal Plains Without EDB

Ralph Motsinger and Johnny Crawford


 
ABSTRACT

After the loss of DBCP researchers quickly provided rates and application techniques for use of EDB for nematode control in cotton. Thus, cotton farmers still had an effective, low-cost nematicide that could be applied at planting without phytotoxicity. With these materials farmers have over the years tended to develop a "chemicals alone" approach to nematode control. Many growers applied these materials as an insurance policy against "possible" nematode damage rather than according to recommendations based on a nematode assay.

With the loss of EDB, nematicides which have potential for nematode control in cotton include 1,3-Dichloropropene (1,3-D), fenamiphos, aldicarb and carbofuran. All of these materials are cleared for nematode control on cotton except carbofuran. When compared with EDB, these materials have some shortcomings: they are more expensive and, with present rates and application techniques, are less effective.

The 1,3-D nematicide must be applied pre-plant unless research can demonstrate an effective rate that can be applied at planting without phytotoxicity. The other chemicals are non-fumigant, or contact materials, which need additional research on rates and application techniques to determine the role they should play in a cotton nematode control program.
