Please Note: The CTAHR publications database reflects over a century of study by researchers and extension agents in the College. Much of the information contained in earlier publications is still of practical and technical use, and the documents are an unparalleled resource for Hawai'i agricultural and horticultural history. However, some publications also make recommendations that are no longer in accordance with more recent advances in understanding. For instance, they may specify pesticides or methods of using them that are no longer allowable under current State or federal regulations. Before using any pesticide, always read its label for approved uses, and follow label directions for application. Other publications may advocate the use of particular plant species that are now considered invasive. The Invasive Species Council is continually making assessments on this matter; see their Web site at http://www.hawaiiinvasivespecies.org for the latest recommendations on identification and control of these species.
