Response to sulfonylurea herbicides was investigated in three Lindernia weeds {L. procumbens (Krock.) Borbás, L. dubia var. major Pennell and L. dubia Pennell var. dubia} using plants from different sites in the Tohoku region of Japan. Plants of L. dubia var. dubia from a paddy field of Yuza Town, Yamagata Prefecture, were resistant to bensulfuron-methyl with a I₅₀ value (concentration of bensulfuron-methyl for inhibiting dry matter production of weeds by 50%), 5, 110 times higher than that of the plants from Shizukuishi Town, Iwate Prefecture, in the Wagner pot experiment (Fig. 1, Table 1). In the deep petri dish experiment, plants of L. procumbens from Yuza Town, L. dubia var. major from Tajiri Town, Miyagi Prefecture, and L. dubia var. dubia from Yuza Town, were also resistant to bensulfuron-methyl with a I₅₀ value, 60.7, 10, 200, and 14, 100 times higher than that of the susceptible plants of each species from Omagari City, Akita Prefecture or Shizukuishi Town (Fig. 2, Table 1).<br>The plants of L. dubia var. dubia from Yuza Town showed a cross-resistance to the other sulfonylurea rice herbicides, such as ethoxysulfuron, cyclosulfamuron, azimsulfuron, imazosulfuron and pyrazosulfuron-ethyl in the treatment of the recommended dosage in this region (Table 2, Table 4). Preemergence application of pretilachlor, bifenox and cafenstrole controlled the resistant plants effectively in the Wagner pot experiment (Table 3). Naproanilide and simetryn/thiobencarb/MCPB controlled the resistant plants effectively when applied at the 1st leaf stage of the weeds in the Wagner pot experiment (Table 3). Application of herbicides including pretilachlor or naproanilide, simetryn/thiobencarb/MCPB and bentazone controlled the resistant plants effectively in the field experiment (Table 4). Application of herbicides containing these ingredients, therefore, could be effective for the control of resistant Lindernia in paddy fields.
