Kuk YI, Jung HI, Kwon OD, Lee DJ, Burgos NR, Guh JO: Sulfonylurea herbicide-resistant Monochoria vaginalis in Korean rice culture. Pest Manag Sci. 2003 Sep;59(9):949-61.
In vitro acetolactate synthase (ALS) activity of the R biotype was 183, 35, 130 and 31 times more resistant to imazosulfuron, bensulfuron-methyl, cyclosulfamuron and pyrazosulfuron-ethyl, respectively, than the S biotype.
Sulfonylurea-based mixtures, except ethoxysulfuron plus fentrazamide, did not control resistant M. vaginalis. |
