Demonstate the effects of water rate on velocity and Jaguar for the control of wild radish (10WE16) locations
Aims
  • To evaluate the effect of water rate using a medium spray quality on bromoxynil based herbicides under conditions where coverage is not optimal.
  • To evaluate the effect of coarse droplets.
  • To evaluate the effect on wild radish control at different water rates with MCPA in tank mixtures with Velocity.
Key messages
  • The wild radish population was consistent and of high density (303 /m2) across the site. Spray coverage was affected due to the high weed density and with 65% of the wild radish 4 leaf or larger across the site at application shading was also an influence.
  • This trial was applied immediately after rainfall so soil moisture was good but the weeds had just endured a fortnight of frosts with very dry conditions and were still highly stressed.
  • Coverage issues and the seasonal conditions prior to application coupled with ongoing dry and stressed conditions following application have contributed to lower than expected wild radish control from all treatments in this trial.
