A 1:1 mixture of Paraquat and Picloram at 12 lb./A. or 2,4-D:2,4,5-T (1:1) at 24 lb./A. generally desiccated and defoliated more leaves during the first month after treatment, but Picloram at 6 lb./A. caused more defoliation 12 months after treatment. Camasey was more susceptible to the herbicides tested than guava, mango, and rose apple. ER -
