Yellow-vein in Citrus
scales per 100 leaves varied from 3.3 to 8.7. Scales containing active forms of Aphytis numbered in excess of 18 per 100 healthy scales each month, and in one month were as high as 183 per 100 healthy scales. These figures demonstrate that Aphytis was active during each of the 15 months and present in sufficient numbers to hold purple scale at low level regardless of weather fluctuations. This ...
متن کاملA novel approach for simultaneous detection of Citrus yellow mosaic virus and Citrus greening bacterium by multiplex polymerase chain reaction
A method of multiplex polymerase chain reaction (PCR) was developed for the simultaneous detection of Citrus yellow mosaic virus (CYMV) and fastidious Citrus greening bacterium, Candidatus Liberibacter asiaticus (CLa) in sweet orange trees. Initially total DNA from individual CLa and CYMV infected citrus plants were mixed and both pathogens were detected simultaneously by multiplex PCR. Subsequ...

متن کاملCitrus tristeza virus-host interactions
Citrus tristeza virus (CTV) is a phloem-limited virus whose natural host range is restricted to citrus and related species. Although the virus has killed millions of trees, almost destroying whole industries, and continually limits production in many citrus growing areas, most isolates are mild or symptomless in most of their host range. There is little understanding of how the virus causes sev...
متن کاملPast and future of a century old Citrus tristeza virus collection: a California citrus germplasm tale
Citrus tristeza virus (CTV) isolates collected from citrus germplasm, dooryard and field trees in California from 1914 have been maintained in planta under quarantine in the Citrus Clonal Protection Program (CCPP), Riverside, California. This collection, therefore, represents populations of CTV isolates obtained over time and space in California. To determine CTV genetic diversity in this conte...
