Replication Data for: Integration of mathematical modeling and target-based application of biocontrol agents for the control of Botrytis cinerea in vineyards

Biocontrol agents (BCAs) were used both in calendar- (based on four growth stages, i.e., flowering, pre-bunch closure, veraison, and before harvest) and predictive model-based strategies (only when Botrytis cinerea infection risk was predicted by the model). The BCAs applied during the seasons were selected considering the grapevine growth stages. Treatments performed with BCAs were compared with synthetic fungicide treatments and an untreated control. The trials were conducted in three experimental vineyards with four epidemics. To evaluate the level of gray mold control of each treatment, disease severity was assessed at harvest and the presence of latent infection was evaluated.The integrative use of the predictive model and BCAs provided satisfactory levels of gray mold control, with gray mold severity levels significantly lower than those of the untreated control, which had severity values similar to those observed with synthetic fungicides following both calendar and model-based strategies.生防制剂（Biocontrol Agents, BCAs）的施用方式分为两类：一类为固定周期施药，基于开花、果穗封闭前、转色期及采收前四个葡萄生育阶段实施；另一类为基于预测模型的防控策略，仅当模型预测到灰葡萄孢（Botrytis cinerea）侵染风险时方可开展施药操作。本试验季所使用的生防制剂均依据葡萄生育阶段进行筛选确定。将生防制剂处理组与合成杀菌剂处理组及空白对照组进行对照比较。试验在3个试验葡萄园中开展，共涉及4次灰霉病流行事件。为评估各处理的灰霉病防控效果，于采收期调查病害严重程度，并检测植株组织内潜伏侵染的发生情况。将预测模型与生防制剂整合使用可获得令人满意的灰霉病防控效果，其灰霉病严重度显著低于空白对照组；而无论是按固定周期策略还是基于模型策略施用的合成杀菌剂，其病害严重度与空白对照组相近。
