“…) and laboratory experiments (Calvo‐Garrido et al . ) and, to our knowledge, the present research and the client reports on PRT published by Henry Manufacturing Ltd (http://www.henrymanufacturing.co.nz/products/protectorhml/) are the only studies showing efficacy of fatty acid–based NPs against B. cinerea of grapes in the field and in laboratory studies. Nonetheless, other fatty acid–based products effectively controlled B. cinerea in other fruit crops, such as ECO‐100 SC applied postharvest on apples (Montealegre et al .…”

Aims: To investigate the efficacy and mode of action of the fatty acid-based product Foodcoat â (FC) against Botrytis cinerea. Methods and Results: In vitro, in vivo and field experiments were carried out to investigate the effect of different concentrations of FC on B. cinerea germination and infection of grape leaves and berries, using three selected isolates and comparing results with those achieved by the commercialized product Protector HML (PRT). Furthermore, the effect of field applications of FC on the grape berry microbiota was investigated. FC reduced B. cinerea germination and grape berry severity by up to 54 and 96%, respectively, compared with the untreated controls. Conclusions: Foodcoat demonstrated efficacy that was equal or greater than the registered product, PRT. A multiple mode of action was hypothesized for FC suppression of B. cinerea, including: inhibition of germination and germ tube alteration, protection of host green tissues and enhancement of the natural yeast populations on the berry surface. Significance and Impact of the Study: The efficacy of both products has been quantified and their modes of action described, suggesting them for field applications against B. cinerea, alone or in combined strategies. This is also the first report of a fatty acid-based product stimulating natural yeast populations on grape berries.

“…Actually, B. cinerea incidence is favored by high humidity and long wetness duration . Additionally, in the present study climatic conditions could be considered more favorable for C. sake CPA‐1 survival and efficacy than in other growing seasons (2009 and 2010) in the same experimental field when BCA efficacy was significantly higher with coating additives . Despite the mean averages of temperature and RH being very similar, during 2009 and 2010, accumulated rainfall was 28.0 mm and 30.2 mm, respectively, whereas during 2015 and 2016, accumulated rainfall raised to 56 mm and 34 mm, respectively.…”

“…Following this concept, several new approaches to strengthen biological control are being studied. These approaches include the combination of two or more antagonistic strains, the induction of natural biological processes (e.g., inducing systemic resistance) (El Ghaouth et al, 2003;Reglinski et al, 2005), the use of natural antimicrobial products (e.g., chitosan, lysozyme) and plant resistance (Calvo-Garrido et al, 2013, 2014bDroby et al, 2009). In addition, the identification and use of yeasts, which are normal components on the surface of grape berries, have been studied for their capacity as biocontrol agents (Nally et al, 2012;Parafati et al, 2015;Vargas et al, 2012).…”

Gray mold caused by Botrytis cinerea limits grape production in Chile

2015

View full text Add to dashboard Cite

by Botrytis cinerea is a major disease of grapes (Vitis vinifera) that substantially reduces the yield and quality of grape production in temperate and humid regions of the world. B. cinerea is a necrotrophic fungus that attacks the non-lignified aerial organs of grapes; in particular, berries are highly susceptible during ripening. The polycyclic nature and exponential progress exhibited by GM at the beginning of the its epidemic, as well as the abundant inoculum production, the high dissemination efficiency, the wide host range and the high genetic variability of B. cinerea, explain the difficulties encountered in attempting to control GM. At present, integrated disease management, including cultural and chemical control, is the main control strategy. These control measures can be used to reduce the initial inoculum or to lower the disease infection rate. However, control measures that reduce the infection rate are the most effective means of controlling GM. Important progress toward understanding the complexity of the biology and epidemiology of this pathogen has occurred in recent decades. This has allowed the improvement and development of more effective and sustainable control strategies against B. cinerea. This review article provides a recent update regarding grape GM, with special emphasis on Chilean production conditions.
