• Do not make more than one application per season to:– Hydrangea, Impatiens spp., crotons (Codieum spp.), Fuschia

hybrids, Petunia, Peperomia, stock, or cyclamens (Cyclamen spp.).

• Extensive phyto screening has been done with Kontos, however, it is always a good idea to test tank mixes prior to commercial applications.


• Application tips:– Apply early in the cropping cycle, prior to

heavy infestations– Root system must be present for effective

control as a drench.– Applications may benefit from the addition of

a surfactant.
