Delving into the Latest Updates on Syngenta Agro AG with Synapse

Overview

An overview is given of cooperative studies designed to minimize ochratoxin A contamination of wine.Aspergillus carbonarius was identified as the fungus responsible for ochratoxin A formation in grapes.Fluazinam, cyprodinil, and fludioxonil were active against the fungus in vitro and in vineyards.Damage from grape caterpillars was an important factor promoting ochratoxin A formation.Application of insect growth regulators (lufenuron and fenoxycarb) reduced ochratoxin A levels.Effects of agronomic factors are also considered.Recommendations for integrated pest control are made.

Author: Bac, Valerie ; Gueunier, Monique Martins ; Albert, Jean-Philippe ; Drouillard, Jean-Baptiste

Grape fruit and wine quality can be damaged by Botrytis sp., Penicillium expansum, Aspergillus carbonarius and Trichothecium roseum.An in vitro assessment of IC50 germinative and mycelium growth was carried out on these fungi for the main botryticides of the market.The botryticide activity of these fungicides is confirmed.Cyprodinil, fludioxonil and fluazinam showed high levels of activity against all the tested fungi.Practical solutions for vineyards are discussed.The assessed references present a tighter spectrum or even a specific botryticide activity.
