Dual Functional Salts of Benzo[1.2.3]thiadiazole-7-carboxylates as a Highly Efficient Weapon Against Viral Plant Diseases

Nowadays, plant protection against viral diseases is one of the most challenging tasks faced by modern agriculture. One of the possible ways of plant protection is utilization of systemic acquired resistance phenomenon. In this approach biological or chemical factors interact with plants and stimulate their immune system against infections before infection occurs. This paper presents 11 ionic derivatives of benzo[1.2.3]­thiadiazole-7-carboxy-S-methyl ester, a synthetic plant resistance inducer, with counterions specifically selected to modify the physical and biological properties of the resulting salts. We present the synthesis methods, as well as physical and biological properties, of these newly obtained anionic bifunctional salts.
