Effect of viral inhibitors in the control of Papaya ringspot virus and productivity in papaya (Carica papaya)

Abstract

The papaya (Carica papaya) is a fruit tree very accepted in the export market for generating high profitability, growing in Mexico in tropical and subtropical areas. The Papaya ringspot virus (PRSV) causes the most restrictive diseases of production of this crop in Mexico and the world, therefore, the effectiveness of Inhibitovir® and Virus Stop® was evaluated on field to 3 mL L-1 and 6 mL L-1, on incidence, intensity and control of virosis, plant height, stem diameter, number of flowers and fruits, fruit weight and yield. The PRSV was detected until the fifth moth after the transplant, time for the plantation to achieve a good mooring of fruits, however, the efficacy of the viral inhibitors did not have significant differences on control plants infected with PRSV, as well as on plant height, stem diameter, number of flowers and fruits, fruit weight and yield.
