“…The following is the mechanism of herbicidal action for each herbicide: ACN, inhibition of porphyrin biosynthesis (Koura et al 1994); Daimuron, inhibition of seminal root elongation (Ogasawara et al 1991); Cafenstrole, inhibition of elongation at the growing point (Kanzaki et al 2001); Azimsulfuron, inhibition of acetolactate synthase (ALS), which is involved in biosynthesis of branched-chain amino acids (Shirakura et al 1995); Cyhalofop-butyl, inhibition of fatty acid synthesis by activity inhibition of acetyl-CoA carboxylase (ACCase) (Ito et al 1998); Bensulfuron-methyl: inhibition of ALS, which is involved in biosynthesis of branched-chain amino acids (Yuyama et al 1987).…”

“…1,2) Generally, the herbicidal activity and selectivity of herbicides on weeds and crops are known to be affected by various environmental factors, such as temperature, water leakage, soil texture and water overflow. [3][4][5][6][7][8][9][10][11] However, the effects of these environmental factors on the herbicidal activity and phytotoxicity of ipfencarbazone have not been verified.…”

Ipfencarbazone exhibits excellent herbicidal activity against Echinochloa spp. and is safe for transplanted rice at a dose of 250 g a.i./ha. However, the effect of various environmental factors on its activity has not been verified. The present study evaluated the factors affecting the herbicidal activity of ipfencarbazone against Echinochloa spp. and its phytotoxicity to transplanted rice. The herbicidal activity and phytotoxicity of ipfencarbazone were barely affected by temperature, soil texture, water leakage, or flooding water depth. When an overflow was conducted artificially 6 hr after application, the herbicidal activity was stable. Furthermore, ipfencarbazone completely inhibited the emergence of Echinochloa spp. for 56 days regardless of the soil texture, water leakage and overflow conditions. When the period between application and reflooding was within 24 hr of herbicide application, the phytotoxicity of ipfencarbazone on transplanted rice was slight. These results suggest that ipfencarbazone shows stable efficacy in practical use.
