- We learned in October of 2017 that cranberry (i.e. the bushberry and low-growing berry subgroups) received a U.S. label for Movento®. Over the subsequent years (2018 to 2024), this product proved to be our most effective one yet for killing the larvae of cranberry tipworm. Movento’s active ingredient (spirotetramat) belongs to the “Group 23” insecticides, which are described as tetronic & tetramic acid derivatives. They work by inhibiting the formation of lipids in the insects that are vulnerable to that particular chemistry. We had never had a Group 23 cranberry insecticide in our toolbox prior to this material, so this offered a brand new mode of action against tipworm.
