ACIBENZOLAR-S-METHYL Usage And Synthesis
DescriptionAcibenzolar-S-methyl (Novartis) has attracted special attention because it acts against a very wide range of plant diseases but does not directly affect the growth or metabolism of the causal organisms. It is known to act by stimulating systemic activated resistance (SAR) in the treated plant. The well-established compound probenazole, which for some years has been the leading treatment for rice blast in Japan, is thought to act in a similar way. Pathogen resistance to probenazole has not developed, and such stability of performance may well be a general feature of SAR-inducing compounds.
UsesAcibenzolar-S-methyl is a S-methyl thioester derivative of acibenzolar. Acibenzolar-S-Methyl acts as a fungicide in pesticidal formulations.
UsesPlant disease resistance activator.
UsesCGA245704 is used to control a range of diseases in wheat and it is being developed for use on rice, bananas, vegetables and tobacco.
DefinitionChEBI: A benzothiadiazole that is the S-methyl thioester derivative of acibenzolar. It is used as a fungicide and plant activator on a variety of crops, including cotton, chili peppers, lettuce, onions, spinach, tobacco, and tomatoes.
Metabolic pathwayVery little information on the fate of CGA245704 has been published. It is readily degraded in soil and plants and it is rapidly eliminated from animals. A partial metabolic pathway is shown in Scheme 1.
DegradationCGA245704 is a stable substance and it is very stable in solution other than at high pH values. Its DT50 values (20 °C) at pH 5, 7 and 9 were 3.8 years, 23 weeks and 19 hours, respectively (PM). Hydrolysis of the thioester link and ring opening would be anticipated.
