“…Biocontrol agents have been mainly applied at postharvest conditions due to their narrow range of activity; however, the BCAs application at preharvest conditions could improve their commercial success . In this way, some coating additives as Fungicover® were required to improve C. sake CPA‐1 efficacy under environmental stress conditions . Fortunately, a high compatibility with phytosanitary products commonly used in viticulture has been also confirmed for C. sake CPA‐1 …”

“…demonstrated the potential of Candida sake CPA‐1 for biocontrol of BBR of grapevine with heat‐adapted cells and especially with the addition of a fatty acid‐based additive called Fungicover® (FC) as an edible coating. Later, biological control efficacy of CPA‐1 with FC was confirmed in an organic vineyard under both Mediterranean and Atlantic climatic conditions . Recently, the efficacy of C. sake CPA‐1 plus FC has been demonstrated in commercial conditions and their compatibility with the phytosanitary products commonly used in viticulture has been studied .…”

“…The reduction of CPA‐1 cells in the PS formulation was significantly lower after 72 h of establishment. The benefits of an establishment period before exposure to limiting conditions or simulated rainfall were also demonstrated for the liquid formulation of CPA‐1 blended with Fungicover®. Promoting an effective establishment of BCAs could be crucial, and several studies also tested some protectants to enhance the viability of cells after application and to protect BCAs against abiotic factors …”

BACKGROUND The efficacy of Candida sake CPA‐1 as a biocontrol agent against several diseases has been studied since it was isolated 20 years ago. However, it was only recently that two suitable and effective film‐forming formulations based on potato starch and maltodextrins were developed using the fluidized‐bed spray‐drying system. The present work aimed to confirm the capability of both novel formulations by testing their resilience on grapes at different temperatures (0, 22, and 30 °C), relative humidities (40% and 85%), and simulated rainfall levels. Another objective was to examine the control of Botrytis cinerea in different hosts. RESULTS The CPA‐1 cells from both dried formulations survived better than the liquid formulation on grapes stored at 0 and 22 °C regardless of the relative humidity. After simulated rainfall, potato starch formulation achieved significantly higher populations than maltodextrin formulation, although the highest reduction was −1.6 log N N0−1. A positive effect of cell establishment prior to the simulated rainfall was shown, and recovered cells from the potato starch formulation were significantly higher after 72 h of cell establishment. Finally, both formulations reduced the incidence and severity of B. cinerea on pears, apples, and tomatoes. CONCLUSION The potential of these novel film‐forming formulations of C. sake CPA‐1 was verified. The resilience of formulated C. sake was better than the commercialized liquid formulation, the adherence of the formulations to the grapes improved after an establishment period prior to rain exposure, and the control of B. cinerea was verified in a wider range of hosts. © 2019 Society of Chemical Industry

The interaction between environmental factors that are expected to occur in response to climate change (CC) will have a significant impact on food security and availability. Little information exists on how elevated temperature, drought stress and increased CO will have on the efficacy of biocontrol agents. The impact of these factors on the viability of different formulations of the biocontrol yeast Candida sake on the surface of grapes berries was evaluated for the first time. Such knowledge is critical for projecting the efficacy of biocontrol under climate change conditions and to identify formulations that have the necessary resilience to perform under CC conditions.
