Reduction of lodging in cereals and maizeSpecific scope: This Standard describes the conduct of trials for the efficacy evaluation of plant growth regulators used to reduce lodging in cereals (excluding paddy rice which is covered by EPPO Standard PP1/145 Reduction of lodging in paddy rice).

Abstract In 2022, a suspected incursion of Oryctes rhinoceros (coconut rhinoceros beetle, CRB) was reported in Bahía de Banderas, Nayarit, México, based on damage symptoms observed on coconut palms and photographs of beetles on a social media site. This prompted collaboration with local biologists and land managers, and a survey of the area with the suspected invasion was carried out in 2024. Adult beetles and larvae were collected, and morphological features were consistent with taxonomic characteristics of O. rhinoceros . Damage to coconut palms consistent with that caused by O. rhinoceros was observed and photographed in the locations where the beetles were captured. Molecular analysis confirmed the specimens' species identity as O. rhinoceros , belonging to the CRB‐G (clade I A ) haplotype grouping. The Oryctes rhinoceros nudivirus, a biocontrol agent which is widespread in coconut rhinoceros beetle populations in some Pacific islands, was not detected. Reports of O. rhinoceros on iNaturalist, the results of this survey and DNA analysis confirm that O. rhinoceros has established for the first time in the Americas in Bahía de Banderas on the border between Nayarit and Jalisco. While the current infestation area is limited, a thorough delimiting survey should be carried out as soon as possible, and a response plan should be prepared to contain or eradicate the pest before it spreads.

Abstract Preparedness for plant pest outbreaks through contingency planning is an effective approach to ensure a rapid response. Within the European and Mediterranean Plant Protection Organization (EPPO) region, Xylella fastidiosa has significant economic, environmental and social impacts in some member countries, as well as its potential for spread to other member countries. To enhance preparedness for this pathogen, a contingency planning simulation exercise workshop was jointly organized by EPPO and the Near East Plant Protection Organization. The event took place over 3 days in May 2025 in Tunisia. A total of 69 participants from 21 countries attended the workshop. The attendees came from diverse plant health backgrounds, including experts from National Plant Protection Organizations, international organizations, plant health scientists, policy officials, inspectors, quarantine officers, and pest control specialists. Participants were divided into six groups, each acting as an outbreak management team tasked with addressing the challenges of an X. fastidiosa outbreak. The scenario was based on the first detection of X. fastidiosa at an olive nursery in a fictitious country called Surveyland. As the scenario progressed over a simulated one‐year timeline, each team had to organize themselves to manage a range of issues designed to mimic the fictitious but realistic development of an X. fastidiosa outbreak.
