Distribution of glyphosate-resistant and glyphosate-susceptible hairy fleabane (Conyza bonariensis) in central California and their phenological development

A survey of central California was done for distribution of glyphosate-resistant and glyphosate-susceptible hairy fleabane. Some populations from this collection were grown in pots in the full sun, their growth and development was monitored, and a degree day model for the phenological development of spring-emerging hairy fleabane was developed.
