Lane 9 bp molecular weigth marker. Control of Botrytis bunch rot of ripening grapes: Con el tiempo y el avance de la enfermedad las hojas se arrugan por los bordes y se abarquillan. The fungus Botrytis cinerea Pers.

The cinerrea differentiation between the Mendoza and Champagne populations showed P values of less than 0.

Allele not reported for this population. Due to the fact that no boty -only, flipper- only, or vacuma -type isolates were identified in this study, we cannot conclude that these sibling species are sympatric in Mendoza vineyards. Considering the amount of data previously published at the time of the study, PCR-RFLP and presence of transposable elements were chosen as genotyping methods.

Reductions in bunch rot in Rhine Riesling grapes from bunch thinning. Conclusions These comparisons between fungal populations, led to the detection of a high level of diversity and the differentiation between local and French groups of isolates. Midseason bunch rot of grapes: The isolates that shared the same haplotype were not related geographically.

Integrated disease management The considerable increase in the understanding of B. PCR amplification was performed using primers for the ribosomal intergenic spacer IGSthe nitrate reductase and ATP synthase genes previously reported by Giraud et al. Authors have nothing to declare. This isolate was kindly supplied by Dr. There is a long history of studies on Trichoderma spp.

For the 36 samples that were analysed 35 local strains and the previously genotyped vacuma foreign strainthe amplified PCR products showed the expected size for all the targets tested.

Recently, Vercesi et al. These comparisons vic fungal populations, led to the detection of a high level of diversity and the differentiation between local and French groups of isolates.

Microbial Vd of Botrytis spp. A significant difference in allele frequency was recorded between the local and French populations. Therefore, these areas act as completely isolated regions.
