Extract

Four samples of D-D were tested at six dosage levels for their nematicidal activity against the potato-root eelworm Heterodera rostochiensis; the treatments were carried out on naturally infested soil in 5-in. pots, viability being estimated by hatching in root diffusate. There was no evidence of there being significant differences between the samples at 50–60% kills, but at higher and lower kills they did appear to differ appreciably from one another in nematicidal activity.
