摘要

Of 78 biotypes of wild radish(Raphanus raphanistrum)collected from Western Australia (WA), 42/100 were resistant and 14/100 intermediate to acetolactate synthase(ALS)-inhibiting herbicides. Based on the LD_50 and GR_50 ratios. The resistant biotype K96071 was 81-fold more resistant to Chlorsulfuron and 114-to 116-fold more resistant to metosulam than the susceptible biotype K96041. More resistant biotypes were found in northern zones than in southern zones of WA.
