When I lightly brushed the plant to see if any insect made an appearance I was greeted by little whiteflies trying to make their escape. These insects – which are not true flies – are a lot like aphids in that they suck juices from plants.
If you suspect you have whiteflies in your plot, brush the plant leaves like I did and watch. You can also confirm your suspicions by looking under the leaves for insects, frass or a shiny, sticky substance they produce called “honeydew.”
As a control, I used an organic insecticidal soap and washed the plants. I’m sure this will need to be repeated to be effective.
