和歌山県におけるトマト葉かび病菌の薬剤感受性と各種薬剤の防除効果

抄録

This study investigated the sensitivity of 92 isolates of Passalora fulva from tomato plants in Wakayama Prefecture to thiophanate-methyl, penthiopyrad, boscalid, azoxystrobin, and triflumizole using agar dilution methods. All isolates exhibited reduced sensitivity to more than two fungicides. Bioassays using tomato seedlings showed that mancozeb WP (wettable powder), TPN WP, and iminoctadin-albesilate WP were effective against two strains resistant to multiple fungicides.
