Anthracene Technique for Evaluating Canopy Density Following Application of Herbicides
Abstract:A quantitative means for evaluating absolute or relative light intensity under a forest canopy is described. The method makes use of 5 ml vials of anthracene in a benzene solution placed at selected locations. The polymerization of anthracene to dianthracene is dependent on the amount of incident light. The remaining anthracene can be determined in a spectrophotometer. The method is particularly designed to measure the reduction of leaf canopy after herbicidal sprays. This permits a quantitative evaluation of the effectiveness of the herbicide.
