Abstract
The objective of this work was to evaluate three strawberry cultivars in an organic production system combined with the application of biological products via leaf for the control of Botrytis cinerea aiming at increasing fruit productivity and quality. The experimental design was randomized block, in a 5x3 factorial scheme, consisting of four products and three cultivars. The treatments consisted of the biological products Onix (Bacillus methylotrophicus), Quartz (Bacillus amyloliquefaciens), Botector (Aureobasidium pullulans), Prestop (Gliocladium catenatum) and control (water application in the plot) in combination with three strawberry cultivars (Cristal, Monterey and Pircinque). Through the results it was possible to observe the superiority of the cultivar Cristal in the total fruit production when compared to the cultivars Monterey and Pircinque. The biological products Onix, Quartz and Botector provided higher total strawberry production. The recommended cultivar for planting in the southern region of Minas Gerais is Pircinque due to the high levels of soluble solids and total sugars observed. The application of biological products was effective in controlling Botrytis cinerea.
Highlights
Strawberry production in a sustainable way has been gaining ground in the markets, since consumers are looking for healthier foods that are less aggressive to the environment (Caproni et al, 2013)

Significant interaction was observed between the application of biological products and strawberry cultivars in relation to the number of fruits with symptoms of gray mold (Botrytis cinerea) and total sugars
Summary
Strawberry production in a sustainable way has been gaining ground in the markets, since consumers are looking for healthier foods that are less aggressive to the environment (Caproni et al, 2013). Gray mold (Botrytis cinerea) is an important and frequent pathogen in strawberry fruits, affecting petioles, flower buds, petals and peduncles in atypical favorable environments (Braun & Sutton, 1978). This fungus causes great damage to strawberry producers in the South of Minas Gerais, causing rot in strawberry fruits when they are still in the field, leaving the fruits unfit for consumption. This disease can cause losses of 20 to 30% in production depending on the high humidity and rainy season
