Abstract: | A study was conducted in two greenhouses with a history of Fusarium crown and root rot (Fusarium oxysporum f.sp.radicis-lycopersici, Forl) and root-knot nematodes (Meloidogyne javanica andM. incognita). During the 2005–06 growing season, the effectiveness of soil disinfestation by solarization in combination with low doses
of metham-sodium (500, 750, 1000 and 1250l ha−1) or dazomet (400 g ha−1), was tested against soilborne pathogens and nematodes in an attempt to find a suitable alternative to methyl bromide, which
is soon to be phased out. Solarization alone was not effective in the greenhouse with a high incidence ofForl. In the greenhouse with a low level ofForl, all the treatments tested reduced disease incidence, and were therefore considered to be applicable for soil disinfestation.
In addition, root-knot nematode density decreased with all the treatments tested in both of the greenhouses. |
