In this study, we investigated the persistence of the introduced bacterial strain <i>Pseudomonas sivasensis</i> CF10PS3 in the wheat phyllosphere using a novel qPCR probe protocol.

Our qPCR assays, designed to specifically detect CF10PS3, distinguished it from naturally occurring <i>P. sivasensis</i> strains, providing precise insights into its dynamics in the field. The experimental results indicated that CF10PS3 was already present on the wheat leaves before its application, suggesting its natural adaptation to the foliar environment. Following initial application, a significant increase in CF10PS3 was observed, though subsequent environmental factors such as rain and wind might have caused notable fluctuations in its population. Despite these variations, the introduced strain showed considerable persistence, with population levels significantly higher than those in untreated plots by the end of the study period. This research underscores the importance of understanding bacteria dynamics in the field, highlighting the influence of environmental conditions on their efficacy. The use of specific qPCR probes proved effective in monitoring introduced strains, offering valuable insights for optimizing biocontrol agent application strategies.
