Conteúdo: |
Leprosis is currently considered the main viral disease for the Brazilian citrus production due to the high costs of the chemical control of its vector Brevipalpus phoenicis (Acari: Tenuipalpidae). The global importance of citrus leprosis has recently increased with the northbound spread of the virus to new areas in the Americas, presently occurring from Argentina to Mexico. Sweet orange (Citrus sinensis L. Osbeck) varieties are the most affected genotypes, while other citrus species and hybrids are considered resistant to leprosis. However, field evaluations of 34 accessions of mandarins and their hybrids revealed that approximately 60% of them exhibit leprosis symptoms, often in leaves and seldom in fruits and stems. These data corroborate the information that mandarin genotypes show some level of resistance to the disease, but most of the accessions can still host the virus and could be sources of inoculum in the field. |
