Uptake, distribution and persistence of systemic fungicides in large palms
2010 | Monica Elliott, University of Florida
The overall objective of this research is to determine the uptake, distribution and persistence of selected systemic pesticides in large palms (mature palms with trunks) over a defined time period. The initial focus is on currently registered systemic fungicides that have the potential for management of the two Fusarium wilt pathogens (F. oxysporum f. sp. canariensis and f. sp. palmarum).
Study Results
We have clearly demonstrated that it is possible for xylem-mobile fungicides to move passively into the palm canopy (via trunk infusion) and persist for at least 120 days if the formulation is compatible with palm uptake and a sufficient quantity of fungicide is applied. Furthermore, the fungicides are moving into leaf tissue that was in development (not yet emerged) at the time of the fungicide application. Issues with formulation and application method still need to be resolved, and it still needs to be determined if the fungicides would be efficacious against specific palm diseases. However, simply knowing that these fungicides are present in palm tissue provides the first step in developing fungicide management programs.
