Abstract: Considering the positive and especially negative sides of the use of chemical plant protection products, attention is increasingly being directed towards finding, and using products of natural origin that have qualities that affect harmful microflora and microfauna. The study conducted tested the effectiveness of different concentrations of orange oil against Phytophthora infestans, Alternaria solani and Aphis gossypii. A variety of reactions of the tested pathogens and aphid to the tested products were established. Against Phytophthora infestans, the best results on the 7th and 9th day of reporting (over 50% efficacy) were observed in the three concentrations of the products Oo1 and Oo2. The average effectiveness for the entire reporting period was highest for Oo1 – 1% - 63.76%. Against Alternaria solani, it was found that the initial effect of the tested products was very good, but a gradual decrease in the effect was observed in the following days. On average for the reporting period, the highest efficiency was registered with product Oo1 – 1% (47.91%). The results obtained in the experiments against Aphis gossypii show that the relatively best efficiency of the four tested variants is the product Oo1 in a concentration of 1% - 56.02% on the 5th day after the third treatment. It proves that with the increase in the concentration of the tested products, the sensitivity of the tested pathogens and enemies also increases. Best results against Phytophthora infestans, Alternaria solani and Aphis gossypii show product Oo1 in highest test concentration 1%.
