Abstract
BACKGROUND:Bacillus amyloliquefaciensstrain CPA-8 has been described as an effective biocontrol agent to control brownrot in stone fruit for both preharvest and postharvest applications. However, no information about the environmental fate andbehaviour of this strain under field conditions is available.RESULTS: The dispersion of the CPA-8 application was evaluated using water-sensitive papers, and complete coverage wasobserved on the leaves of treated trees, while<1% of non-treated tree leaves had CPA-8. CPA-8 persisted on the fruit of treatedtrees during preharvest and postharvest conditions, while a significant decrease on leaves and weeds was observed 21 daysafter treatment. On non-treated trees, CPA-8 was detected on leaves until 180 days after treatment, and on weeds, the CPA-8population was dependent on the distance from the treated trees. A high persistence of CPA-8 was detected on inert materials,suchasclothesandgloveswornbyhandlersandplasticharvestingboxes.Morethan99%ofthesampleswithaCPA-8phenotypewere confirmed as CPA-8 using polymerase chain reaction (PCR).CONCLUSION: This work demonstrated a good distribution, persistence and adaptation of the CPA-8 strain to field andpostharvest conditions. Monitoring of dispersion and persistence is an excellent tool to determine the time of application andprovides valuable information for registering issues.© 2017 Society of Chemical Industry
