Ridomil

RIDOMIL GOLD/BRAVO , chlorothalonil, 115 Riedel-deHaen, See Sigma-Aldrich Laborchemikalien GmbH (Germany), 165... 

Ridomil, with which the treatment with starch solution was not carried out, is said to yield brown chromatogram zones on a pale yellow background [14]. Hence, it may be assumed that this detection is based not on the iodine azide reaction but on the physical adsorption and enrichment of iodine in the lipophilic chromatogram zones (cf. Iodine Reagents ).

Three acylalanine compounds, metalaxyl (Ridomil), cyprofuram (Vini-cur) and benalaxyl (Galben), have been tested extensively for control of grape downy mildew in New York. None of these compounds are currently registered in the US. They are narrow spectrum, but highly effective compared to standard protectants such as captan, folpet or mancozeb. They have local systemic activity and possess protectant and antisporulant, as well as after-infection activity. Similar to the EBI compounds, the after-infection capabilities and their activity over extended intervals (14-21 days) make the acylalanines desirable tools for IPM programs.

Even the relatively non-nucleophilic 2,6-dimethylaniline reacts with the methyl 2-trifloxy ester analog 191 (17 h at room temperature) to give the oW-arylalanine ester 192 in high yield. Acylation with methoxyacetyl chloride gives the fungicide Ridomil (193) [70].
