more thorough search of the literature. The table should only be used for making rough comparisons and for noting the order of magnitude of the values given
The acreages are from Strickland (1966) and calculated from Woodford ( 1964). the LD50 figures principally from Negherbon (1959). Woodford and Evans (1965
and Martin (1963). J S. Alabaster (personal communication) and J. H. Stevenson (personal communication).
