ダゾメット微粒剤と太陽熱利用土壌消毒の組み合わせによるトマト青枯病に対する防除効果

抄録

Dazomet combined with soil solarization showed a superior control of tomato bacterial wilt to methyl bromide. One month after the treatment, the residue of dazomet in the soil was reduced to 0.2% of that immediately after treatment, which was almost the same at transplanting time of tomato seedlings. The results suggested that dazomet combined with soil solarization could decrease the phytotoxicity by the residue of dazomet and the number of times of removing the gas from the soil.
