Application Notes
2,6-Dichloroisonicotinic acid was the first synthetic chemical found to induce SAR (systemic acquired response) (Ward et al., 1991). The mechanism by which this works is 2,6- Dichloroisonicotinic Acid binds the SA-binding protein/catalase and inhibits its enzymatic activity (Conrath et al., 1995)
