 note = {1 ) Nematodes were greatly (upmost 99%) reduced in top10 cm soil of a field after the solarization for four-weeks by 0.02 mm polyethylene-film mulch in July, but survived in the deeper soil. 2 ) Effect of solarization (four week treatment) to nematodes was highest in August, higher in June and July, but low in May and September. 3 ) Root-knot nematode, Meloidogyne incognita, was not isolated from soil in a polyethylene bag after treatment by a water bath in 50℃ for 1 hr., 45℃ for 4hrs. and 40℃for 72hrs. 4 ) Root-lesion nematode, Pratylenchus penetrans, was not isolated from soil in a polyethylene bag after treatment by a water bath in 50℃ for 1 hr., 45℃ for 72hrs. and 40℃ for more than 120hrs. 5 ) Free-living nematodes (mainly Rhabdlitida) were isolated from soil in a polyethylene bag after treatment by a water bath in 50℃ for 24hrs., 45℃for 72hrs. and 40℃ for 168hrs. This shows that these nematodes are more tolerant to high temperature than plant-parasitic nematodes, and the former can be used as the indicator to check the solarization effects to soil nematodes including plant-parasitic forms. 6 ) According to these results, no nematicidal treatment are needed for plant-parasitic nematode control in carrot production in the Kanto district (central Japan) by the four-week solarization by polyethylene-film mulch before sowing in fine/hot weather condition (year). In this case, it is necessary that the field is fertilized and tilled before the solarization, and sowed the carrot seeds without tillage after this treatment for preventing contamination of the deeper soil of high nematode density to the top soil},
