Cani use Malathion 55% as a root Drench ?
Can I use Malathion 55% on my bonsai trees as a root drench for root aphids and other harmful insects in the soil?
Also, what would the mix rate be for this type of application?
Thanks

Hi-Yield 55% Malathion Insecticide Spray is labeled for treating aphids as a foliar application only to established ornamental shrubs/trees. It would not be applied as a soil drench and would not be effective in this application.
