An acylamino acid fungicide.
Benalaxyl is used for the control of Oomycetes on a wide range
of crops, fruit, flowers, ornamentals and turf.
ChEBI: Methyl N-(2,6-dimethylphenyl)-N-(phenylacetyl)alaninate is an alanine derivative that is the N-phenylacetyl derivative of methyl N-(2,6-dimethylphenyl)alaninate It is an alanine derivative, an aromatic amide, a carboxamide and a methyl ester.
The fate of 14C-benalaxyl as affected by mancozeb is
determined on the surface and in the tissues of grape
leaves 7 days after the single foliar application of a
mixture with mancozeb. The main oxidative scheme
with rat liver microsomes is quite similar to that
observed in plants. The only differences are
represented by a further hydroxylation on the second
ortho methyl group, and only traces of the meta
hydroxylation take place on the xylene ring.
Benalaxyl is stable in aqueous media over a wide pH range but it is hydrolysed
in concentrated alkali. Its DT50 at pH 9 and 25 °C is 86 days (PM).
It is reasonably stable to sunlight in aqueous solution. When irradiated
in solution with UV light (254 nm) it is degraded with a half-life of
55 minutes (Pirisi et al., 1996). Products were compounds 2 and 3 (see
Scheme 1) which are common also to metalaxyl and furalaxyl. These
were detected in a non-labelled study. Under simulated sunlight its
half-life was 167 days.
