Abstract
The sticky disease was first reported in the south of Bahia in 1980 and today it is the most important disease of papaya. Its etiology is still little known in spite of the fact that isometric virus particles have been found in affected plants. In this work, we have tried to find other hosts for this disease. The plants were mechanically inoculated using leaves, latex and bark as green-fruit inoculum sources. Plants from Leguminoseae, Chenopodiaceae, Solanaceae, Passifloraceae, Graminaeae, Compositaea, Euphorbiaceae, Caricaceae, Malvaceae and Pedaliaceae were evaluated. Papaya plant were inoculated by cuts with needles and razor blades and by lateral grafit. The plants were observed over 60 days for symptom expression. To evaluate the inoculation's efficiency, double stranded RNA (dsRNA) was extrated from the tested plants. None of the evaluated indicators developed symptoms, but dsRNA of 6x10 on sisty potencial D were found in needle-inoculated papaya plants.Downloads
