Due to regular cultivation of strawberries in the same location, growers have encountered problems with soil-borne pathogens and pests in strawberry production. In recent years, new products with antagonistic or biostimulant activity have entered the market. The objective of this study was to evaluate the potential for reducing crop damage by using a combination of products. The experimental plot was established on the Jarkovič farm in Brod v Podbočju in 2020 and 2021. The trial was divided into three plots. The control plot was untreated, in the second plot products of the company 'Atens' ('Team horticola' and 'Condor shield') were used, and in the third plot products of the company 'L.G. Italia' ('Ken', 'Klozer', 'Sphera', 'Carbogen', 'Start' and 'Algalis') were used. The products of 'Atens' were used after planting during vegetation and the products of 'L.G. Italia' were used before planting. We measured vegetative growth, yield and quality of yield. Vegetative growth was better in the plots where the products were used, root weight and plant weight were higher. The treated plants had a 33% higher yield than the control plants, and the fruits were also larger. The content of dry matter, vitamin C, sugars, acids and phenols was higher in the fruits of the control plants, they also had firmer skin. The fruits of the control plants and of the plot 'LG Italia' reached a high taste quality, while those of the plot 'Atens' reached a medium taste quality. The products used had a good influence on vegetative growth and yield. However, due to the higher yield, the quality of the fruits was lower. Although the quality was lower, the fruits achieved the desired flavour. Higher yield with medium and high flavour quality means that the use of products is a good method to reduce soil pathogen problems in strawberry production and a solution for better farm management.
