Summer Weed Time of Removal Trials locations
Aims

Assess the yield impact of different summer spray application timings at four trials in March 2017, following a widespread summer rainfall event.

Key messages
  • Time of weed removal at the high rainfall site did not affect canola yield but the canola had a higher biomass when weeds were removed earlier.
  • The medium rainfall site had consecutively higher wheat yields with earlier times of weed removal; however these were not significantly different.
  • At the low rainfall site plots sprayed for summer weeds had significantly higher oat yields than unsprayed plots. Timely control of summer weeds increased soil moisture and nitrate conservation.
