Common Pest Control Methods for Populus Trees

Common pests affecting Paulownia trees include aphids and red spiders. The Paulownia shield aphid is one of the common insect pests affecting Paulownia, belonging to the Homoptera order and the Aphididae family, a monophagous pest that only infests Paulownia trees.
To combat aphids, spray with a 1000-1500 times concentration of oxamyl solution. For red spiders, use a 1000 times concentration of dimethoate emulsion. To prevent and control various pests and diseases, mix furamidine with the soil and gradually infiltrate it into the tree trunks.
