Effects of Fumigant and Nonfumigant Nematicides on Pratylenchus penetrans and Yield of Potato.


In 1984-85 metham-sodium and the combination of 1,3-dichloropropene plus aldicarb decreased (P = 0.05) soil population densities of Pratylenchus penetrans at planting, midseason, and at harvest relative to the untreated control. These treatments increased (P = 0.05) marketable potato tuber yield from 27% to 46% in 1984 and from 23% to 37% in 1985, as… (More)
