The objective of this work was to evaluate the effect of different
techniques to modify grape cluster architecture on the incidence and severity
of botrytis bunch rot, as well as on the viticultural performance of the
'Sauvignon Blanc' grapevine (Vitis vinifera). Associated with fungicides, four
treatments were tested: control, 30 ppm gibberellic acid sprayed at full bloom,
1,000 ppm prohexadione calcium sprayed at full bloom, and berry thinning at
the stage of beginning of berry touch. The experiment was carried out in the
2015, 2016, and 2017 vintages. Clusters were treated with fungicides during the
stages of full bloom, beginning of berry touch, veraison, and around 15 days
before harvest. Berry thinning does not cause losses in the yield and quality
of 'Sauvignon Blanc', and, despite having little effect on cluster architecture,
is effective in reducing the incidence and severity of Botrytis cinerea.
Prohexadione calcium improves grape phenolic maturation, is effective
in reducing the incidence and severity of B. cinerea, and reduces cluster
compactness by decreasing berry diameter. The application of gibberellic acid
spray at full bloom is not recommended because it decreases yield and bud
fertility and increases berry susceptibility to B. cinerea infection. |
