Control of Meloidogyne chitwoodi in Potato with Fumigant and Nonfumigant Nematicides
During 1993-94, several fumigant and nonfumigant nematicides were tested alone and in combination at various rates for control of Columbia root-knot nematode (Meloidogyne chitwoodi) in potato. Ethoprop, oxamyl, or metam sodium alone did not adequately reduce tuber infection. Metam sodium plus ethopr...

| Zusammenfassung: | During 1993-94, several fumigant and nonfumigant nematicides were tested alone and in combination at various rates for control of Columbia root-knot nematode (Meloidogyne chitwoodi) in potato. Ethoprop, oxamyl, or metam sodium alone did not adequately reduce tuber infection. Metam sodium plus ethoprop reduced culled tubers to 3%, and metam sodium plus 2 or 3 foliar applications of oxamyl reduced culls to </=10% in all but one instance. Fosthiazate provided excellent control of tuber infection with or without metam sodium. Rates of 1,3-dichloropropene (1,3-D) below 234 liters/ha did not always adequately control tuber damage, but 140 liters/ha of 1,3-D plus ethoprop reduced the percentage of culled tubers to zero. 1,3-Dichloropropene plus chloropicrin did not provide better control than 1,3-D alone. Combinations of 1,3-D at 94 liters/ha or greater plus metam sodium at 374 liters/ha or greater consistently provided excellent control of tuber damage by M. chitwoodi and would be the treatment of choice where soilborne fungal pathogens are also present |
