Goosefoot (Chenopodium pumilio) was investigated to minimise its toxic effects on crops and pastures in Western Australia. It was clearly demonstrated that the toxic effects were mitigated by early control of goosefoot followed by adequate rainfall. The critical amount of rainfall was found to be between 50 and 65 mm. Post-seeding rains were also effective in diluting and leaching the toxins from the seed zone, as noted in a time of sowing experiment. A delay in sowing of only one week resulted in the est lishment of healthy wheat and lupin crops in contrast to two weeks for the more sensitive canola and legume pastures. The differential sensitivity to the toxins was also noted at the varietal level of each species. However, no outstandingly tolerant spe
