Several new herbicides and herbicide combinations were evaluated in the greenhouse for control of honey mesquite, huisache, whitebrush, live oak and Texas persimmon. Sprays of picloram, triclopyr ester and 3,6-dichloropicolinic acid at 0.56 kg/ha were the most effective herbicides in reducing the canopy of honey mesquite. Picloram at 0.14 to 0.56 kg/ha effectively defoliated huisache. At 1.12 kg/ha tebuthiuron, buthidazole, hexazinone and 3,6-dichloropicolinic acid also defoliated huisache. Whitebrush was effectively controlled with picloram, triclopyr ester, tebuthiuron, buthidazole, hexazinone, dicamba and ethidimuron at 0.56 kg/ha. None of the treatments was effective against live oak or Texas persimmon. Certain combinations of picloram plus triclopyr effectively defoliated whitebrush and honey mesquite. Picloram plus 3,6-dichloropicolinic acid was also effective for honey mesquite control.
