Citrus stubborn disease orchard. In addition, it is important to closely monitor the weeds in young orchards to ensure that they are not susceptible to "Spiroplasma citri", and if susceptible ones appear, to remove them as soon as possible"." Citrus stubborn disease The Citrus stubborn disease is a plant disease affecting species in the genus "Citrus". "Spiroplasma citri", a Mollicute bacterium species, is the causative agent of the disease. It is present in the phloem of the affected plant and transmitted by several leafhoppers including "Circulifer tenellus" (beet leafhopper) and "Scaphytopius nitridus" in citrus-growing regions of California and Arizona and "Circulifer haematoceps" in
