More water may lift herbicide hit

Plain text source: 
Preliminary results from a trial in the south-east region of South Australia suggests higher water rates (of up to 100 litres per hectare in a trifluralin/Avadex Xtra mix or 150L/ha for other products) can improve the efficacy of pre-emergent herbicides in stubble-retained systems... Early results from the project suggest higher water rates do improve the efficacy of ryegrass control, particularly with Sakura ... We want to look at the differences between herbicide mixes, so we are hoping to conduct the trial again this year as there may have been environmental effects on herbicide efficacy...
