ABSTRACT

Vapam (sodium methyldithiocarbamate) is being considered as an alternative to Telone II (1,3-dichloropropene) for control of root-knot nematodes (Meloidogyne incognita) in cotton. Two separate test plots were established to compare Vapam and Telone II for nematode control and cotton yield. Vapam was applied at the manufacturer recommended rate of 6 gallons per acre; Telone II was applied at 3 gallons per acre. An untreated check was provided. There were four replications in each field. Both Telone II and Vapam resulted in lower numbers of root-knot nematodes. Yields were increased by both the Vapam and Telone II with no significant difference between the two.
