The need for accurate informnifo eg gOru L. safety on foliage
Hints continues to expand as new ps idas-awpTnts are tested yearly.
*y little cumulative information exists on phytotoxicity of many pesticides
imonly used on foliage plants. Many growers develop their own lists of safe
,ticides for their crops through trial and error, but results of testing
ler controlled conditions are beneficial to these growers as well as those
;h limited pesticide experience.
The chart that follows was developed originally in 1983 to partially fill
* gap in this information. It does not include all pesticides available to
iamental producers or all of plant species grown in Florida. The chart is
iply a compilation of available data on phytotoxicity trials conducted with
iage plants. Many additions have occurred in the past two years for both
i and established compounds. The response of the plant to the recommended
;e of the pesticide applied at recommended intervals is noted as either S
ife) or U (unsafe), with the number of letters in each. square denoting the
fiber of separate trials involving that combination. The type of
ftotoxicity (U) is categorized by a number which is indexed at the end of
Several points should be stressed regarding the use of this information.
'st, only shaded squares represent legal uses. Second, only the plant
;ted was tested, and other species of the genus may or may not respond simi-
rly. Third, in cases in which the fungicide or bactericide is not
ecifically named, several similar compounds manufactured by the same or
Fferent companies were included over the years in which these tests were
ducted. Finally, some combinations were safe in some trials and unsafe in
iers. These situations must be considered as questionable, and use of the
)duct on that plant considered marginally safe.
