Hi Yield Malathion 55% is only labeled for tomatoes, cabbage and potatoes. It is not labeled for use on squash or cucumbers. You should wait at least 7 days before you harvest tomatoes after they have been treated with Malathion 55%. Please refer to the Hi Yield Malathion 55% product label for the complete usage instructions.
