Mode pyridalyl

New agrochemicals introduced in the past five years include new chemistries with known modes of action, such as the protoporphyrinogen inhibitor bencarba-zone, the phytoene desaturase picolinafen and beflutamid, and sodium channel pyrethroids new chemistries with possibly new modes of action, such as flonic-amid and pyridalyl and new chemistries with established new modes of actions, such as flubendiamide, which activates ryanodine-sensitive intracellular calcium release channels, ryanodine receptors RyR, in insects.

Thus, the symptoms and diagnoses in insects or cells described above suggests that pyridalyl has a different biochemical mode of action from any existing insecticides. The lack of cross-resistance between any existing insecticides also supports such a presumption. Studies to clarify the biochemical mode of the action are on-going. 

Pyridalyl resulted from a major synthetic program based on a series of lead conq)ounds and has proven to be very active against the larvae of some inq>ortant pests of cotton and vegetable crops. Pyridalyl also controls insecticide-resistant strains of lepidopterous pests as well as susceptible strains. It produces unique insecticidal symptoms so t it may have a different mode of action from any other existing insecticides. Pyridalyl is safer to mammals and various beneficial arthropods so that it Avill provide an mq)ortant tool in IPM and insecticide resistant management programs. Pyridalyl will become a safer chemical, and certainly contribute to establishment of sustainable chemistry.
