Shredding and Spraying Honey Mesquite

Abstract

Shredding and spraying honey mesquite is an effective method of control. Overall, the highest percent root mortalities were obtained from treatments applied in May, but shredding and spraying were effective when applied during other months of the year, even during the fall and winter. Root mortalities obtained from aqueous solutions of either 2,4,5-T amine or picloram plus 2,4,5-T during the year were dependent upon water content and temperature in the upper 15 cm of the soil (2,4,5-T, R=0.88; picloram plus 2,4,5-T, R=0.82). Average root mortalities for all months were consistently the greatest from picloram plus 2,4,5-T (57%), followed by dicamba (34%) and dicamba plus 2,4,5-T (31%). Root mortalities obtained from 2,4,5-T amine (26%) and 2,4,5-T ester (25%) were the lowest obtained in the study.
