The pathogen has a cosmopolitan presence that includes Southeast Asia, but to date, bud rot has not been reported in this region. This study provides an overview of the potential risk of Malaysian <jats:italic>P.\u00a0palmivora<\/jats:italic> isolates cross\u2010infecting other host species, including cocoa, durian, rubber and Malaysian oil palm planting materials (<jats:italic>Dura<\/jats:italic>\u00a0\u00d7\u00a0<jats:italic>Pisifera<\/jats:italic>, D\u00a0\u00d7\u00a0P). On cocoa pods, the durian isolate PP7 caused dark brown necrotic lesions. Detached leaf bioassays showed that <jats:italic>P.\u00a0palmivora<\/jats:italic> isolates PP3 and PP7 infected different hosts, except rubber foliage without wounding. Inoculation tests on cocoa, durian and rubber seedlings caused brown necrotic lesions when stems were wounded, with 10% mortality in cocoa and durian at 17\u00a0days post\u2010inoculation (dpi). However, no further infection was observed, and lesions closed within 14\u201328\u00a0dpi on the non\u2010wounded seedlings. Pathogenicity tests of oil palm seedlings inoculated with isolates PP3 and PP7 indicated that Malaysian <jats:italic>P.\u00a0palmivora<\/jats:italic> isolates were not pathogenic to oil palms based on localized infection observed only through wounding. Overall, the work demonstrated that Malaysian <jats:italic>P.\u00a0palmivora<\/jats:italic> isolates were able to cross\u2010infect multiple hosts but did not show severe infections on oil palms.<\/jats:p>","DOI":"10.1111\/efp.12557","type":"journal-article","created":{"date-parts":[[2019,9,18]],"date-time":"2019-09-18T17:57:21Z","timestamp":1568829441000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Pathogenicity of Malaysian <i>Phytophthora palmivora<\/i> on cocoa, durian, rubber and oil palm determines the threat of bud rot disease"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7946-7097","authenticated-orcid":false,"given":"Intan Nur Ainni","family":"Mohamed Azni","sequence":"first","affiliation":[{"name":"Ganoderma and Diseases Research for Oil Palm Unit Biology Division Malaysian Palm Oil Board Kajang Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7912-828X","authenticated-orcid":false,"given":"Shamala","family":"Sundram","sequence":"additional","affiliation":[{"name":"Ganoderma and Diseases Research for Oil Palm Unit Biology Division Malaysian Palm Oil Board Kajang Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasagi","family":"Ramachandran","sequence":"additional","affiliation":[{"name":"Ganoderma and Diseases Research for Oil Palm Unit Biology Division Malaysian Palm Oil Board Kajang Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,9,18]]},"reference":[{"key":"e_1_2_6_2_1","volume-title":"1944","author":"Alibert H.","year":"1959"},{"key":"e_1_2_6_3_1","unstructured":"Bunting B.
