Überwachung und Bewertung der Huanglongbing-Krankheit (HLB) der Calamansi

Citrus Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is one of the most severe diseases affecting the citrus industry. Given the recent emergence of the disease and its vector, we need to be aware of the scenario of the Calamansi industry concerning the occurrence of the disease in order to formulate solutions that can help protect and save Calamansi production, especially in Oriental Mindoro, to maintain the title of 'Calamansi King.' The aim of this study was to gather initial data on the awareness of Calamansi farmers regarding the HLB disease, the extent of the disease's occurrence in five municipalities in Oriental Mindoro using the starch-iodine test, and to determine the impact of rainfall on the occurrence of HLB. The survey was conducted among 140 citrus farmers, representing 5.91% of the total Calamansi farmers in the five municipalities of Oriental Mindoro. The results showed that Calamansi farmers in the five municipalities lack awareness and familiarity with the occurrence of HLB.
