  • A series of bicyclic 4,5,6,7-tetrahydroindazole derivatives 6 have been synthesized, and their herbicidal activities were studied in flooded paddy condition. The compounds 6 showed herbicidal effects to barnyardgrass and Monochoria and good tolerance against rice at a rate of $0.063kg/ha{\sim}0.25kg/ha$.

  • A series of N-{2,4-dichloro-5-(3-pyrazolyl)Phenyl}imides 7 and 8 was prepared and evaluated their herbicidal activities. Those compounds in which either carboxylate or carboxamide moiety is on pyrazole moiety 7c-71 showed no herbicidal activity whereas, the compounds in which trifluoromethyl group is substituted in pyrazolyl moiety showed moderate herbicidal activities against barnyardgrass, monochria and flat-sedge under paddy conditions with good rice tolerance at rate 63-250 g/ha.

  • 3,4-Dimethyl-N-[4-chloro-2-fluoro-5-{(pyrazolylmethyl)oxy}phenyl]maleimides or 3,4,5,6-tetrahydro-N-[4-chloro-2-fluoro-5-{(pylazolylmethyl)oxy} phenyl]phthalimides were prepared and evaluated their herbicidal activities under paddy conditions. Those compounds which have N-methyl-5-pyrazolylmethyloxy moiety showed good tolerance in transplanted rice and strong herbicidal activities on barnyardgrass below 60 g/ha of dose.

  • New series of 9-(5-Isoxazolemethoxyphenyl)imino-8-thia-l,6-diazabicyclo[4.3.0]nonan-7-one which are the cyclic imide type compounds were designed and synthesized. The herbicidal activities of main dominant weeds to these compounds were evaluated under rice field condition. There is the possibility for a new herbicide since the most of compounds were excellent to main dominant weeds occurring in rice field without the serious rice injury.

  • Of the cyclic imide type compounds, S-275 was known to exhibit a potent herbicidal effects. We have designed and synthesized the compounds having diverse subsutuents in place of the chlorine group of bicyclic 4,5,6,7-tetrahydroindazole part of S-275. Their herbicidal activities were studied under flooded paddy conditions. The results showed that the most compounds gave relatively weak herbicidal activities, whereas tile compound substituted with methylthio group showed potent herbicidal effects against paddy weeds at a rate of 0.015 kg/ha and improved tolerance on rice compared to S-275.
