Full Name: Demonstrations of residual summer weed control for the Mid North, South Australia
Funding Body: GRDC
Duration: 2024 – 2026
Project Lead: UNFS

Site Locations: Booleroo, Pt Germain, Balaklava
AIM: To identify different residual summer weed control options, in order to reduce the number of summer spray passes required in the Mid North, South Australia.
Background: “NGN forums in the Mid and Upper North highlighted summer weed control costs as an important area of concern. Summer weed control can be costly, with some growers reporting three to four passes in order to conserve moisture and nutrients for the following season. This investment will assist growers in making informed summer weed management decisions around the utilisation of knockdown and residual herbicides in summer fallow situations and how they stack up against regional practice. The investment will also link into other investments to leverage their impact and ensure that growers are aware of best practice summer spray management and limit off-target damage to other crop types in the region, namely horticulture.
Beginning in the Summer of 2024/2025 UNFS will deliver three herbicide demonstrations conducted in small plot trials to compare the efficacy and longevity of control of summer weeds. These demonstrations will build on the information delivered through the current investment with Hart Field Site, HFS2306-002SAX.”
