Spanish Moss on Pecans: Epiphyte, Not Parasite

Spanish moss (Tillandsia usneoides) is an epiphytic bromeliad, not a true moss. It uses trees for support, absorbing water and nutrients from air. It doesn't kill trees but heavy infestations can shade leaves and weigh down branches.

Control is rarely needed. If desired, copper fungicides labeled for ball moss (e.g., TC Tribasic Copper Sulphate) work. Apply before bud break or mid-summer to avoid tender leaf damage. Hand removal is labor-intensive. Baking soda (40 lb/100 gal) shows efficacy but isn't labeled. Light infestations are harmless and indicate clean air.
