Sakura 850 WG influence of rainfall after sowing for annual ryegrass control under heavy stubble conditions locations
Aims
  • To demonstrate the influence of rainfall on Sakura uptake.
  • To highlight the influence of a drying top soil when weeds have already germinated prior to application of Sakura.
  • To influence of rainfall to carry herbicide to soil active zone.
  • To make a comparison between root (Sakura) and shoot uptake herbicides (trifluralin, Boxer Gold®, Avadex® Xtra) efficacy including residual control over time.
Key messages

Using an effective knockdown with broad spectrum pre-emergent grass herbicide like Sakura can deliver excellent weed control, yields and return on investment not just in the year of application but in following seasons due to a reduction in the seed bank when combined with a complete integrated weed management program across the farm.
