Published online by Cambridge University Press: 31 May 2012
Extract
During July, 1943, a number of wild and cultivated plants in the Blackwell district, near Sarnia, Ontario, were examined for parasitic nematodes. Wild host-plants of the sugar-beet nematode, Heterodera schachtii Schm., recorded in a note in the Canadian Entomologist of October, 1941, were again noted, and one new host record was obtained for this nematode in Canada.
