<i>A priori</i> contrasts used to determine toxicity of extracts relative to controls and differences of extract toxicity within plant species following analyses of <i>Phoma</i> hyphal growth, <i>Fusarium</i> hyphal growth, and <i>Artemia</i> survivorship in response to plant extracts versus controls.

<p><i>Notes:</i> Plant extracts are only compared within plant species for each bioassay.
