APPLICATION
Apply when weeds are actively growing.
Ensure thorough coverage of weeds.
Where crop or weed density is high,
increase water volume.
In most situations the rate specified for
Qld, NSW, Vic, each weed size will give satisfactory
SA, WA, NT only control. However, under certain
conditions such as:
SA only
• high crop and weed density,
• late season germinations,
• abnormal weed growth (including
WA only
early flowering);
higher rates of product (up to the
maximum rate of application specified
for that weed) may be required.
Barracuda will not effectively control:
All states
• regrowth of suppressed weeds,
• transplanted weeds,
• regrowth from rhizomes or roots,
• weeds growing under stress from
previous herbicide applications.
Wild radish
Effective residual activity of this product
may be reduced where :
• rates lower than 1.2 L/ha are used;
• dry conditions prevail;
• poor coverage of the soil surface is
achieved;
• crop is grown in non-wetting sand;
• soils have a high content of clay or
organic matter.
