PHYTOTOXICITY OF SOME FUNGICIDES USED

The need for accurate information regarding fungicide safety on
foliage plants continues to expand as new pesticides and plants are added
yearly. Very little cumulative information exists on phytotoxicity of
many fungicides commonly used on foliage plants. Many growers develop
their own lists of safe fungicides for their crops through trial and error,
but results of testing under controlled conditions would be beneficial to
these growers as well as those with limited pesticide experience.

The following chart was developed to partially fill the gap in
this formation. It does not include all pesticides available to ornamental
producers or all of the plant species currently produced in Florida. The
chart is, however, a compilation of available data on phytotoxicity trials
conducted with tropical foliage plants, both previously reported and those
unreported to date. The inclusion of products which are not labeled for
foliage plants does not imply recommendation of their use but is meant to
provide information only. Those fungicides which are labeled for use on
specific foliage plants are shaded gray. The response of the plant to the
recommended rate of the pesticide applied at recommended intervals is noted
as either S (safe) or U (unsafe), with the number of letters in each square
denoting the number of separate trials involving that combination. The
type of phytotoxicity (U) is categorized by a number which is indexed at*
the end of the chart.

Several points should be stressed regarding the use of this infor-
mation. First, only shaded squares represent legal uses. Second, only the
plant listed was tested, and other species of the genus may or may not
respond similarly. Third, in cases in which the fungicide or bactericide
is not specifically named, several similar compounds were included over the
years in which these tests were conducted. Finally, some combinations were
safe in some trials and unsafe in others. These situations must be
considered as questionable, and use of the product on that plant considered
marginally -safe.
