Abstract/Contents:"A putative graminicide-resistant biotype of E. indica (L.) Gaertn. and a wild (graminicide susceptible) biotype were compared with regard to their growth, development and resistance to aryloxyphenoxypropionate and cyclohexanedione herbicides in controlled environment studies. The resistant biotype produced much lower amounts of shoot biomass (46% less) but flowered earlier and allocated a higher proportion and amount of biomass into seed-bearing structures compared with the wild type. The resistant biotype survived the application of 50 g a.i. ha-1 of clethodim, tralkoxydim, sethoxydim, fluazifop-butyl, fenoxaprop-ethyl and diclofop methyl with the greatest resistance bieng shown to the aryloxyphenoxypropionates. At rates of >1000 g a.i. ha-1, trialkoxydim achieved superior control to that of fluazifop-butyl. Even at rates of 4000 g a.i. ha-1, some 50% of the resistant test plants survived the application of fluazifop-butyl. The trait for graminicide resistance did not appear to be strongly heritable, as assessed by the growth and survival of a graminicide-treated F1 population grown in isolation. It is concluded that widespread graminicide resistance in E. indica is unlikely to develop from this biotype."
