Citrus

Sucker Control with Naphthalene Acetic Acid (NAA)

(Reviewed 9/08, updated 9/08)

In this Guideline:
Variety Amount to Use Time
A. NONBEARING CITRUS Direct application of the undiluted see comments below
    formulation (1.15% ethyl 1- naphthaleneacetate)  
  COMMENTS: Restricted entry interval (REI): 12 hours. Use ethyl 1- naphthaleneacetate to control sprouting from scaffold limbs, sprouting from trunks, and sprouting from rootstocks. See label regarding details. Results of research conducted in California and Florida suggest that applications should be made before or during early sprout growth. Heavy application may result in tree damage. In Florida, growers are cautioned not apply after Sept. 1. Use may inhibit sprouting desired for tree recovery following freeze.
