Main Article Content
Abstract
This study was aimed to investigate the causes of unusual pomelo leaf, wavy leaf, after flooding in Nakhon chaisi district and Sarmpran district of Nakhon Pathom Province. The wavy leaf symptoms were found in the branches of pomelo plant introduced from other areas, including Prachin Buri, Chai Nat, Samut Songkhram and some local areas in Nakhon Pathom province. Eighty pomelo leaf samples, 53 with wavy leaf symptom and 27 normal leaves were checked for Citrus Tristeza Virus (CTV) and Candidatus Liberibacter asiaticus (CLA) by polymerase chain reaction (PCR). Results showed that 29 samples were positive to Candidatus Liberibacter while 51 samples were negative including those with wavy leaf symptoms and normal leaf. All samples were negative to CTV detection.
