Abstract/Contents:"Florida golf courses usually contain a large number of pines as a tree component of the ornamental landscape. There are four native species of pine i.e., slash pine (Pinus elliottii var. elliotti), South Florida slash pine (P> elliottii var. densa), loblolly pine (P. taeda), sand pine (P. clausa var. clausa; P. clausa var. immuginata), and longleaf pine (P. palustris), and each is affected by the similar set of soil-related circumastances leading to foliar yellowing. Unless corrected, affected trees continue to exhibit worsening foliar symptoms and reduced annual growth until premature mortality occurs...the use of a triazole fungicide, tridimefon, otherwise known as Bayleton^DR^DG, was investigated due to its interesting plant growth-regulating effects. Chemicals belonging to the triazole class of compounds have been shown to have profound effects on annual as well as perennial plant growth and development depending on the 1) exact compound investigated, 2) rate of application, and 3) host plant treated. In particular, triazoles such as paclobutrazol and tridimefon were shown to affect conifer seedlings by 1) increasing the green color of foliage of treated trees, 2) retarding shoot growth as well as root elongation yet, 3) promoting increased numbers of roots. The shoot growth retardation effect has been shown to be temporary with shoot growth resuming as the triazole is metabolized over time ()...The results of the microinjection trials were initially encouraging but the full potential for canopy re-greening was not realized presumably due to the late start of the injections, i.e., May. Recent research described the maximum rate of slash pine fine root biomass formation occurring during the late Fall and early Spring periods...The second year of the FTGA-sponsored project will begin in January, 1992, to coincide with the optimum period of slash pine fine root biomass production. This should reflect the traditional period for pine injection in Florida."
