A guide to the susceptibility of some tropical crop and pasture weeds and the tolerance of some crop legumes to several herbicides

Abstract

From data generated in replicated pot experiments and validated where necessary in replicated field experiments, a chart of the susceptibility of a range of dicotyledonous and graminaceous weeds of wet tropical Queensland to several herbicides has been prepared. The results are based on percentage dry matter reduction of above ground parts compared to untreated controls. In a similar manner, a chart of the tolerance of a range of arable crop and pasture seed crop legumes grown in Queensland has been prepared and presented. The data in both these charts is continually under experimental review by the authors and represents the state of our knowledge at the time of writing.
