The Effect of the Method of Plant Protection on the Quality of Remontant Strawberry Cultivars Grown in a Gutter System under Covers

To maintain a constant supply of fresh fruit from May to November, producers increase the area of strawberry cultivation under shelters and grow strawberries that repeat fruiting. An additional problem is the reduction of available pesticides caused by the recommendations of the European Green Deal. For these reasons, the authors undertook to compare cultivars to determine which had the best quality fruits and whichplant wasmost resistant to the most dangerous pests.The purpose of this study was to evaluate the effect of the method of plant protection on the health and quality of the fruit yield of three remontant strawberry cultivars grown in a soilless medium. This study evaluated fruit yield and fruit quality as well as the contribution of pathogens to yield losses. For this purpose, standard phytopathological methods were used to identify the causes of disease symptoms on the fruit. At the same time, laboratory tests were carried out on the quality of the harvested strawberries, i.e., firmness and acidity of the fruit, soluble solids content, and respiration rate. The applied protection methods had little effect on the marketable yield and fruit size but had a significant impact on reducing fruit losses caused by the most common diseases. The effectiveness of individual protection methods inreducing the incidence of the tested pathogens and the effect on fruit quality parameters depended on the cultivar and growing season.
