Usage

Uses

Different sources of media describe the Uses of 71626-11-4 differently. You can refer to the following data:
1. An acylamino acid fungicide.
2. Agricultural fungicide.
3. Benalaxyl is used for the control of Oomycetes on a wide range of crops, fruit, flowers, ornamentals and turf.

Metabolic pathway

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.

Degradation

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.
