Relationship of Drop Size and Surfactant to Efficiency of Herbicide

Purpose

To test the effectiveness of various surfactants in five herbicide mixtures. The mixtures will be sprayed over Kromkote cards and magnesium osice slides. This is only testing the effect of surfactants on drop spread. There will be no need to spray any
