Senstar Insecticide protects against woolly apple aphid, pear psylla

Apple and pear growers now have a unique new option to protect fruit from damaging insects. A new Product from Valent U.S.A. is now available for use in pome fruit  

According to a news release, Senstar Insecticide from Valent U.S.A. equips growers with two effective modes of action which each act in unique ways to prevent young insects from growing into adult form to offer growers long-lasting control of soft-bodied insects. Key pests include aphids (woolly apple aphid), mealybugs, and pear psylla. With both translaminar and systemic properties that disrupt all life stages of targeted pests, Senstar helps achieve high-quality, clean fruit from the start. 

“The two modes of action in Senstar have been skillfully formulated to give growers a reliable and user-friendly product that ensures effective mixing and application while providing long-lasting pest control. The dual-action of Senstarprovides effective control of woolly apple aphid like products from long-ago, but instead with two effective and IPM-compatible modes of action,” said Greg Clarke, Valent field market development specialist for the eastern U.S.

Senstar controls pests to protect fruit quality in the following ways:

·      Prevents sticky pears or black sooty mold russet from pear psylla infestations and supports stronger trees by preventing woolly apple aphid feeding on roots and limbs

·      Systemic activity controls pests hiding in bark crevices and colonizes new vegetative growth as well as existing foliage 

·      Fast translaminar movement penetrates leaf tissue to help reach pests that feed on the underside of leaves 

“Growers need to protect their fruit at key points during the season,” added Clarke. “Senstar can be used at petal fall or later as a follow-up to Esteem 35 WP Insect Growth Regulator when needed.”

“For pests like pear psylla, it is important to have a season-long program to keep nymphs from feeding and producing honeydew,” said Allison Walston, Valent field market development specialist for the Pacific Northwest. “Senstar is an effective tool at petal fall to inhibit all life stages from developing and feeding.” 

Senstar is an excellent fit for integrated pest management (IPM) programs by helping growers effectively manage key insect pests with low impact to beneficial arthropods. By combining two different modes of action, Senstar targets all pest life stages, from eggs to sterilizing adults, resulting in long-lasting control. The systemic and translaminar properties of Senstar help to reach out within the canopy where insects feed and breed to optimize control, preventing insects from damaging fruit, protecting yield and delivering marketable apples and pears.

Senstar is part of the Bud to Box product portfolio of solutions from Valent and Pace International that features more than 20 crop production solutions, including new Excalia Fungicide, ReTain Plant Growth Regulator Soluble Powder, MycoApply EndoMaxx, DiPel DF Biological Insecticide Dry Flowable, Esteem 35 WP, and Raynox Sunburn Protectants.
