Transmission through root contact ocurred in seven of 15 plants growing around artificially inoculated plants. In another experiment, every plants was contaminated when a suspension of nematode was placed on the mechanically damaged roots. The young seedlings of nematode was placed on the mechanically damaged roots. The young seedlings did not develop the typical symptoms of red-ring nematode when planted to replace dead plants. It is suggested that seedling tissues are unsuitable for the multiplication of red-ring nematode. This study was conducted to determine if direct transmission of red-ring nematode occurs through root contact and through cultivation practices. Also, the transmission to young seedlings and its susceptibility was investigated. All the work was conducted in a screen house, free from the presence of possible vectors.  aAnel Vermelho  aCoco  aCocos Nucifera  aRaiz  aRhadinaphelenchus Cocophilus  aCoconut  aRed ring  aRoot transmission  aTransmissao1 aBEZERRA, A.
