Vapam (sodium methyldithiocarbamate) is being considered as an alternative to Telone II (1,3-dichloropropene) for control of root knot nematodes in cotton. Three separate test plots were established to compare Vapam and Telone II for nematode control and cotton yield. The Vapam was applied at the manufacturer recommended rate of 6 gallons per acre; the Telone II was applied at 3 gallons per acre. An untreated check was provided. There were four replications of each plot in each field. Nematode numbers were similar at all sampling dates within each site. Telone II resulted in lower numbers of root-knot nematodes at the time of first bloom in two of the three locations, and at harvest in one location. Vapam resulted in lower nematode numbers at harvest in one location. Lint yields were only improved by fumigation in one of the locations. [ABSTRACT FROM AUTHOR] |
