Bacterioses are a significant global problem in plant production. Controlling phytopathogenic bacteria is complex and mostly preventive. Most antibacterial active compounds are copper-based, which are becoming limited in agriculture due to ecological restrictions and the development of resistance in bacterial pathogens. The use of ecologically acceptable natural compounds (plant extracts, essential oils) remains an alternative and insufficiently- considered aspect of plant pathogens, but also animal pathogens contaminating surfaces of plant products. It is known that pawpaw (Asimina triloba L.) preparations have an antimicrobial effect on certain pathogens in medicine and veterinary medicine, and this paper tests their effect on bacteria from the genera Pseudomonas and Escherichia, present on plants. The antibacterial activity of different aqueous extracts of pawpaw tissues was tested in vitro against Pseudomonas tomato and Escherichia coli. A bactericidal effect was found against the P. tomato (the strongest with the seed extract: 92.6% reduction in bacterial colonies compared to the control), while the effect on the E. coli was bacteriostatic (highest with the leaf extract: 34% smaller area of colonies in comparison to the control). In the case of the P. tomato, a bacteriostatic effect was also detected (highest with the twig extract: 92.1% smaller area of colonies compared to the control). The results of the conducted research indicate the perspective of the pawpaw tissue extracts as an agents for combating plant pathogenic and plant contaminating bacteria. |
