Ultor Insecticide Registered

Ultor insecticide from Bayer CropScience was recently registered for use by EPA for control of sucking insects such as aphids, mealybugs, psylla and scales on pome fruits, Christmas trees and hops.

Kevin Adam, insecticide product manager with Bayer, said Ultor is applied to foliage and is distributed throughout the plant by “two-way systemicity.”

Ultor is a lipid biosynthesis inhibitor (LBI). It is active by ingestion against immature insect pests feeding on treated plants.

“Soon after exposure to Ultor, immature target insect pests are trapped in the quiescent stage between molts, and death occurs shortly thereafter due to their inability to progress into the next development stage,”Adam said.

In addition, studies have shown significant impact on exposed female adult target insects by reducing fecundity as well as the survival of offspring, providing more effective overall reduction in pest pressure, he said.

Good coverage of the target plant parts is recommended, as is the use of a spreading, penetrating adjuvant to facilitate uptake by leaf surfaces. However, due to its systemic nature, lower water volume can often be used, Adam said.
