Fenhexamid Resistance in the Botrytis Species Complex, Responsible for Grey Mould Disease
نویسنده
چکیده
The three major fungal pests of grapevine, powdery and downy mildew and grey mould are mostly controlled through the application of fungicides. Some of those are particularly active against the grey mould agent Botrytis cinerea. The panel of fungicides authorized in France comprise since many years anilinopyrimidines, benzimidazoles, dithiocarbamates, dicarboximides, phenylpyrroles and pyridinamines. Lately, the panel has been completed by fenhexamid, a sterol biosynthesis inhibitor (SBI) and the pyridine boscalid, a succinate dehydrogenase inhibitor (SDHI). In addition, a biofungicide based on the Bacillus subtilis strain QST 713 (Serenade) has been authorized in 2010 against grey mould in vineyards. The compounds authorized against grey mould in French vineyards are listed in Table 1.

The hydroxyanilide fenhexamid, one of the latest antibotrytis fungicides, active especially against leotiomycete plant-pathogenic fungi, inhibits 3-ketoreductase of the C-4-demethylation enzyme complex during ergosterol biosynthesis. We isolated Botrytis cinerea strains resistant to various levels of fenhexamid from French and German vineyards. The sequence of the gene encoding 3-ketoreductase,...

In the mild and humid climate of northwestern Europe, fungal pre-harvest rots are a major factor limiting the production of soft-fruits such as strawberries and raspberries. By far the most important fungal disease is grey mould caused by Botrytis cinerea Pers.:Fr., now known to be an aggregate of at least two distinct species (Fournier et al., 2005; Giraud et al., 1999). Primary infections are...

There are several agrochemicals to control Botrytis cinerea, the causal agent for gray mold in grapes, and new ones are being developed. The fungicides used to control Botrytis in vineyards of the Champagne are presented together with some of their deleterious effects on non-target species. Until recently, fungicides basically belonged to three groups: the carbamates, the benzimidazoles, and th...

The effects of the climatic changes more and more frequently, favour the emergence and the development of plant diseases. Botrytis cinerea and Oidium spp. spores are often responsible for enormous productivity losses in cultures with high commercial interests such as the grapevine. This work aims to detect these airborne spores, before the emergence of lesions in Vitis vinifera. In the rural ar...
