Abstract
Bacterial wilt, caused by Ralstonia solanacearum, poses a significant threat to Solanaceae crops, including potatoes. Traditionally, chemical bactericides have been the primary method of disease management. However, the excessive and repeated use of these chemicals has led to the emergence of resistant R. solanacearum strains and raised environmental and safety concerns. Therefore, the current study aimed to explore bacteriophages as a sustainable and eco-friendly alternative to chemical control. Specifically, we evaluated the efficacy of the bacteriophage RsPod1EGY as a biocontrol agent under greenhouse conditions to reduce disease severity and maintain potato productivity. To improve phage survival and activity, we tested six carrier types; compost, peat moss, clay soil, sandy soil, talc powder, and wheat bran. Our findings indicated that compost, talc powder, and wheat bran significantly prolonged the phage’s viability and activity, reducing disease severity by 90%, compared to 65% and 85% for peat moss and phage-alone treatments respectively. In contrast, pathogen control treatments resulted in complete plant mortality. Phage survival was enhanced in pathogen-infected soils, supporting its role in reducing R. solanacearum populations. Potato yield was preserved in compost and talc powder treatments comparable to pathogen-free controls. These results underscore the potential of integrating bacteriophage RsPod1EGY with suitable carriers for sustainable bacterial wilt management, highlighting the importance of delivery methods in agricultural applications.
