Tandem provides spotted lanternfly control

By Mike Agnew, technical services manager, Syngenta

The spotted lanternfly was first identified in Berks county Pennsylvania in 2014. Since then, the USDA has reported that this invasive planthopper, which is native to China, Bangladesh and Vietnam, has spread from Pennsylvania to Delaware, New Jersey and Virginia.

These pests damage trees causing oozing sap, wilting, leaf curling and tree dieback. They also excrete a sugary substance when they feed, called honeydew, that promotes the growth of black sooty mold, which damages plants and can cover patio furniture, cars and more. These insects also affect quality of life and the ability to enjoy the outdoors during the spring and summer as they cover trees, swarm in the air and coat decks and play equipment with honeydew, which is an attractant to other unwanted pests like ants and wasps.

In addition to damaging trees and affecting quality of life, spotted lanternflies are a huge threat to the agriculture industry. They damage crops such as grapes, apples, hops and hardwood trees.

An adult spotted lanternfly is approximately one inch long and half an inch wide. The forewing is grey with black spots and the wings tips are reticulated black blocks outlined in grey. The hind wings have contrasting patches of red and black with a white band. The legs and head are black; the abdomen is yellow with broad black bands. Immature stages are black with white spots, and develop red patches as they grow.

Syngenta has recently registered a FIFRA Section 2(ee) recommendation for Tandem® insecticide for control of spotted lanternflies on plants and structures. With the power of two proven active ingredients, lambda-cyhalothrin and thiamethoxam, Tandem provides a double assault on spotted lanternflies and other pests. Thiamethoxam moves through the plant systemically to help control honeydew-producing pests and any ants tending to spotted lanternflies. For control of spotted lanternfly on ornamental plants, apply Tandem at a rate of 13.9 fl. oz. per 100 gallons.
