Se evaluó la incidencia y la severidad del ?Creasing? en naranja ?Washington? navel y se probaron métodos de control mediante aspersiones foliares de ácido gibérico (GA3. 10 o 20 mg.L-1) acidificado a pH 4.5 ± 0.5, fosfato monoamónico (NH4H2PO4, 2%) y nitrato de potasio (KNO3, 2%), aplicados solos o combinados, en etapas tempranas del crecimiento del fruto (41-55mm). Los experimentos se realizaron durante tres año, en dos plantaciones comerciales ubicadas de Kiyú y Punta Espinillo (35º LS). Se verificaron diferencias en la incidencia y la severidad del desorden entre años, pero no entre plantaciones. Ambas variables se correlacionaron en forma positiva. La aplicación de GA3 solo o combinado con KNO3 o NH4H2PO4 logró reducir en forma significativa el porcentaje de fruta afectada. Sin embargo, el NH4H2PO4 aplicado solo, no resultó efectivo. La aplicación de GA3 realizada al momento de cambio de color de la fruta, fue menos efectiva en el control del desorden y afectó negativamente la coloración en cosecha. La efectividad de los tratamientos fue independiente del grado de incidencia y severidad de ?creasing?. El análisis económico realizado a los tratamientos más efectivos (GA3 solo o combinado con NH4H2PO4) evidenció ganancia incremental en años de baja y de alta incidencia de ?creasing?. |

ABSTRACT.
Bovine viral diarrhea (BVD) affects bovine production and reproduction causing significant economic losses all over the world. Two viral species has been recognized: BVDV-1 and BVDV-2, both distributed worldwide. Recently, novel specie of BVDV named HoBi-like pestivirus was discovered. The presence of BVDV was confirmed in 1996 in Uruguay, however, does not exist until today a schedule of compulsory vaccination along the country. Serological studies with samples from all Uruguayan herds were performed during 2000 and 2001 demonstrating that all of them were seropositive to BVDV with a mean prevalence of 69 %. In addition, there have been no new studies done since those previously described and it is important to mention that the genetic diversity of BVD has never been described in Uruguay. Nowadays, there is strongly suspect that BVDV is one of the most important causes of reproductive failures in our herds. The aim of this study was to describe for the first time in Uruguay the genetic diversity of BVDV with samples collected from different regions along the country. Serological status of 390 non-vaccinated animals against BVDV with reproductive problems from farms of Rivera, Tacuarembó and Florida departments of Uruguay were studied. All herds were seropositive to BVDV and high proportion of animals were positive (298/390), while 4.1 % (16/390) of the animals were positive to Antigen Capture ELISA test and Real Time PCR. Phylogenetic analysis performed with concatenated sequences from the 5′UTR and Npro genomic regions revealed that BVDV-1 and BVDV-2 are infecting our herds, being BVDV-1 the most frequently found. The major subtype was BVDV-1a, followed by BVDV-1i and BVDV-2b. This is the first study that describes the genetic diversity of BVDV in Uruguay and it will contribute to the elaboration of sanitization programs.
