Abstract

Citrus Vein Phloem Degeneration (CVPD) is critical diseases in citrus crops that
caused by Candidatus Liberibacter asiaticus bacteria, which transmitted through
Diaphorina citri. This study aims to examine the effect of Artemisia vulgaris and
Kaolin to Diaphorina citri. The research was carried out in the experimental
garden, Faculty of Agriculture, UPN "Veteran" Yogyakarta, Sleman Regency,
Special Region of Yogyakarta, from March 2023 up to August 2023. This research
was arranged in completely randomized design. First method was non-choice test
with 9 treatments of A. vulgaris are 0.5%, 1%, and 2%, Kaolin 1.5%, 3%, and 5%
and combination of A. vulgaris 0.5% + Kaolin 5%, A. vulgaris 1% + Kaolin 5%, A.
vulgaris 2% + Kaolin 5%. Choice test, persistence test and test for effect the
treatment to the growth of the citrus plants was used the best result from non-choice
test. The results were analyzed using analysis of variance with significant level of
5%. If there are real differences, analysis was continued using the Duncan Multiple
Range Test with significance level of 5%. The application of A. vulgaris
concentration of 1% was have the best potential to against D. citri and did not have
effect to the growth to citrus plants. The persistence test showed that the repellency
effect of A. vulgaris 1% decreased over time. The reduced repellency was because
of bio-pesticides, which are easier to evaporate, and the application better be
repeated.
