Commercial seed of glyphosate-tolerant alfalfa contains small percentages of seeds, called nulls, that do not posses the herbicide trait. Differential competitiveness of glyphosate-tolerant seedlings compared with null seedlings may be detrimental to alfalfa stand density if delayed glyphosate application allows the null and tolerant seedlings to compete with each other. The authors’ objective was to determine if delayed glyphosate application affects plant density of glyphosate-tolerant alfalfa stands.
