CABRERA MEDEROS, Dariel; GARCIA HERNANDEZ, Dahert; GONZALEZ, José Efraín  e  PORTAL, Orelvis. Epiphyte management of Papaya ringspot virus using Zea mays L. barriers in Carica papaya L. Rev. Protección Veg. [online]. 2013, vol.28, n.2, pp. 127-131. ISSN 1010-2752.

The objective of this research was to evaluate the effect of corn (Zea mays L.) barriers intercropped in plantations of papaya (Carica papaya L.) var. Maradol roja on the progress of Papaya ringspot virus (PRSV) epiphytes. For this purpose, evaluations of symptomatic plants were developed every 15 days during 240 days after transplanting. Two treatments were used: the inclusion or not of intercropped corn (MIP-Corn) in the integrated management of papaya with nursery protection and edge barriers of forage sorghum. In the MIP-Corn, a reduction in the area under the disease progress curve (audpc) was observed in comparison with MIP. The intercropped maize barriers had a reducing effect on epiphytes and decreased the incidence and final severity of PRSV in 25 and 17% respectively, compared with MIP. It was demonstrated that the addition of intercropped corn barriers in papaya plantations reduced the damages caused by PRSV in endemic areas of this viral disease.
