New Crop Protection Recommendations for Spotted Lanternfly
February 14, 2019 Grape, apple, and stone-fruit growers in at-risk states have a new option for spotted lanternfly control. Valent U.S.A. LLC has announced a FIFRA Section 2(ee) recommendation for the use of Danitol 2.4 EC Spray on spotted lanternfly. This Section 2(ee) for Danitol 2.4 EC Spray (EPA Reg. No. 59639-35) is now available to grape, pome, and stone fruit growers in New York, Delaware, Kentucky, Maryland, Massachusetts, New Jersey, North Carolina, Pennsylvania, Tennessee, Virginia, and West Virginia.
While spotted lanternfly has been found in apples, it appears to be capable of more damage to grapevines.
Danitol is a fast-acting, broad-spectrum insecticide that kills pests rapidly, providing results within hours. In addition, Danitol has a notably short 24-hour restricted re-entry interval.
“Spotted lanternfly can cause overwhelming damage to a grower’s operation very quickly during the early stages of the growing season, but Danitol is an excellent option for growers needing a strong level of control of this invasive pest,” said Carlos Granadino, Product Development Manager at Valent. “Danitol, when sprayed timely, can provide consistent, reliable and fast knockdown of these pests before they cause physiological damage to the crop.”
In the fall and early winter, adult spotted lanternflies lay their eggs on host-specific species, such as the Tree of Heaven, or Ailanthus, and other tree and vine bark. After the eggs hatch in early summer, the nymphs start feeding by sucking the sap out of the plants, depleting the nutrients and significantly weakening the trees and vines. If the nymphs and adults are left to feed on the crops without using any control tactics, the trees and vines will begin to wilt and eventually die, resulting in devastating damage and yield loss.
To avoid permanent damage to the crops, Granadino said growers should spray Danitol early when populations are beginning to build up.
“Growers should apply Danitol as soon as nymphs begin to appear on the trees or vines and repeat as needed. For resistance management, rotate different types of chemistry and use non-pyrethroid products in rotation with Danitol,” said Granadino.
