Fluopyram has a pronounced action against adults of nematodes. In addition, it causes a delay in the development of eggs which are at an advanced stage and limits their hatching. At the biochemical level it presents a new mode of action as it blocks mitochondrial breathing by blocking the transfer of electrons to the respiratory chain of Succinate Quinone Reductase (complex II- inhibitor SQR). The first symptoms appear about 30 minutes after application as the nematodes begin to move more slowly while after 1-2 hours they are finally completely paralyzed.
