Comparison of Fumigant and Nonfumigant Nematicides for control of Meloidogyne chitwoodi on Potato

The fumigant 1,3-dichloropropene (1,3-D) effectively controlled Meloidogyne chitwoodi on Russet Burbank potato, Solanum tuberosum. There was a maximum of 4% infected and galled tubers from the 1,3-D treatment after 2,028 degree-days with a base temperature of 5 C (DD5). This compared to 66% infected...

520 |a The fumigant 1,3-dichloropropene (1,3-D) effectively controlled Meloidogyne chitwoodi on Russet Burbank potato, Solanum tuberosum. There was a maximum of 4% infected and galled tubers from the 1,3-D treatment after 2,028 degree-days with a base temperature of 5 C (DD5). This compared to 66% infected and galled tubers in aldicarb at-plant treated plots. Soil temperature, as determined by DD5, and timing of chemical applications affected the nematicidal activity on M. chitwoodi (P < 0.05). Aldicarb was most effective when applied postplant (PP) during the nematode reproductive cycle. After 1,684 DD5 of growth, there were 59, 26, 22, and 6% infected and galled tubers from untreated control plots and aldicarb treatments of 2.1 g/m row at 600 DD5, 2.1 g/m row at 1,228 DD5, and 1.3 g/m row at 600 DD5 plus 2.1 g/m row at 1,228 DD5, respectively. No aldicarb treatments were effective over a growing period of 2,028 DD5; 34% of the tubers were infected and galled following the most effective aldicarb treatment (1.3 g/m row at 504 DD5 plus 2.1 g/m row at 996 DD5)
