| Abstract | ||
| The potential of soil solarization with double cover of transparent and black polyethylene sheets at different thickness to control the root-knot nematode Meloidogyne incogaita on tomato plants was studied in a field trial during July – August 2006. All soil solarization treatments either transparent polyethylene upper or black sheets upper greatly suppressed the nematode counts in soil reduced numbers of galls, developmental stages, egg masses per root, nematode final population and nematode reproduction as compared with the nonsolarized plot. All solarized treatments significant decreased nematode criteria when compared with the nonsolarized ones. The highest percentage reductions in such nematode criteria were obtained from soil solarized with 300 µm black upper 300 µm clear, 300µm clear upper 300µm black and 200µm black upper 300µm thickness clear sheets, respectively. Whereas, the least reduction was obtained from soil solarized with 120µm black upper 120µm clear, 120µm clear upper 200µm black and 120µm clear/120µm black sheets respectively. Moreover, all solarized treatments improved tomato growth parameters. The highest percentage increase was observed in soil solarized with black sheets 300µm upper 120, 200 and 300µm thickness transparent sheets. | ||
