This week, I noticed the appearance droplets of sticky sap spotting the leaves of our pecan trees (photo at right). In fact, when standing in the shade of one of our pecan trees, I could feel tiny droplets of plant sap hit my arms and face. It seems we have begun our annual outbreak of pecan aphids and they are covering the tree and everything under the tree's canopy with honeydew.
Rain is forecast for this weekend and a heavy rainstorm can often cause a dramatic drop in aphid populations. If we do receive significant rain, we will need to spray for pecan weevil next week and if aphid populations persist we probably add an aphicide to our weevil spray.
