ResumoSystemic Acquired Resistance (SAR) is an inducible resistance mechanism in plants that, together with other defence mechanisms, provides broad-spectrum and long-lasting disease control. With novel screening techniques the benzo[1,2,3]thiadiazole-7-carboxylic acid derivatives have been identified as a new class of chemicals which stimulate the plant's own defence mechanisms. The synthesis and biological activities of various benzo[1,2,3]thiadiazoles and related structures are described. S-Methyl benzo[1,2,3]thiadiazole-7-carbothioate is the first synthetic chemical ‘plant activator’ that has been developed for this novel disease control concept. © 1997 SCI
