In the conditions of the sandy soils of Dăbuleni, in the period 2020-2022, the aim was to identify some combinations of active substances, to test their effect in preventing and combating pathogens and pests reported during the vegetation period in the sweet potato crop, but also to establish the effectiveness of the application of these products. The best control over the attack of the harmful organisms taken in the study was ensured by the variants in which the Cabrio top and Ortiva 250 SC fungicides were applied in complex with the Mospilan 20 SG insecticides. The combinations of products used in the experimental variants had different effectiveness in terms of the control of harmful organisms that appeared during the vegetation period in the sweet potato crop, depending on the year of the study. Thus, in the variants in which the Ortiva 250 SC product was used in combination, the effectiveness in combating the pathogen Alternaria spp. had values between 82.0% and 89.5%, and in combating the pathogen Botrytis cinerea the effectiveness was between 74.7% and 88.0%.
