SUMMARYIn four trials in sandy soils where beet had previously grown poorly, only slight improvements in growth and yield were obtained after fumigating the soil with dichloropropene‐dichloropropane mixture or chloropicrin. Sugar yields from D‐D treated plots, however, tended to be depressed. Neither the needle nematode (Longidorus attenuatus) nor stubby root nematodes (Trichodorus spp.) were abundant at the four sites.
