Botrytis bunch rot (BBR) – caused by Botrytis cinerea – is usually managed by a routine application of fungicides at: (A) fowering; (B) pre-bunch closure; (C) veraison and (D) pre-harvest.
A 4-year experiment carried out in Italy showed that Trichoderma atroviride, Aureobasidium pullulans and Bacillus subtilis, applied at B, C and D, respectively, provide efficient control of BBR.
Recently, a new epidemiological model for B. cinerea was developed and validated. The validation showed that infections occurring during flowering play a key role in determining the severity of BBR on mature bunches.
New experiments were performed to verify whether BCA applications, based on the disease model, could provide satisfactory disease control when applied in A too.
The paper reproduced in this video-seminar was presented at the International Congress on Grapevine and Wine Sciences - ICGWS (Logroño, Spain, November 7-9, 2018) organized by ICVV.
