Acibenzolar- S-methyl (abbreviation BTH ) is a chemical compound that is used as a fungicide. BTH is derived from Acibenzolar. The active ingredient is engaged with the salicylic acid synthesis and thus leads to the triggering of systemic activated resistance.

It is considered safe for consumers and is already used in tomato against bacterial diseases. In grapes showed experiments that BTH -treated grapes ( presumed antioxidant activity ) contained more anthocyanins than untreated.

After the Maximum Residue Level Regulation of the Federal Ministry of Consumer Protection, only 0.02 mg / kg of BTH may be present in eggs, meat and dairy products.

History
