Guidelines for 2020 Onion Thrips Management in Onion
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program
New York has a variety of registered insecticide products that can successfully control onion thrips. This flowchart provides several different insecticide sequence options for controlling onion thrips in 2020.
Movento® is typically used first, but what should be next? The Guidelines for 2020 Onion Thrips Management provide several different insecticide sequence options to consider for the remaining 2020 season. And remember to always use a surfactant with your insecticide sprays to improve the level of thrips control. Also, do not co-apply insecticides that need to move into the plant including Movento®, Agri-Mek®, Minecto Pro®, Radiant® or Exirel® with chorothalonil (= Bravo) as it reduces the efficacy of the insecticides.
