Abstract

Two hundred and eighty-three compounds were tested for their hatching activity for Heterodera schachtii Schmidt, 31 of these, at the given concentrations, gave hatches equal to or greater than that obtained with beet root diffusate. No correlation was found between hatching activity and redox potential for the 25 redox compounds examined. The structure of the artificial hatching agents and the mechanism of hatching are discussed.
