Control of leaf rust (Puccinia
recondita), stem rust (P. graminis);
suppression of powdery mildew
(Erysiphe graminis)
Control of early blight
(Alternaria solani)
Control of late blight
(Phytophthora infestans)
Control of brown stripe
(Cercosporidium graminis), leaf
streak (Drechslera phlei), and purple
eye spot (Cladosporium phlei)
Application Timing:
160 to 270 mL Apply prior to disease development. If
disease conditions exist, apply again 12 to
14 days later with a fungicide that contains
a different mode of action. Use higher rate
and shorter interval when high disease
pressure.
180 to 270 mL Apply prior to row closure or when
conditions become favourable for disease
development. Apply on a 7 to 14 day
interval. Under high disease pressure, use
higher rate or tank mix with Bravo 500.
It is recommended that no more than 1
application of Headline EC is made before
switching to a fungicide with an alternate
mode of action.
180 to 270 mL Apply prior to row closure or when
conditions become favourable for disease
development. Apply on a 5 to 7 day interval.
Under high disease pressure, use higher rate
or tank mix with Bravo 500. If using a tankmix,
apply on a 7 to 10 day interval. DO NOT
make more than 1 application of Headline
EC before switching to a fungicide with an
alternate mode of action.
162 to 271 mL Apply prior to disease development. Use
higher rate when disease pressure is high.
If disease persists or weather conditions are
favourable for disease development, apply
a second time 14 days later, with a fungicide
with a different mode of action. In absence
of an alternative fungicide registered for the
specific diseases to be treated, for resistance
management purposes, the maximum
number of applications is limited to one.
DO NOT apply more than 162 mL per acre
by aerial application.
*BASF Canada does not recommend use of Headline EC alone on potato due to potential for fungicide resistance.
** Minor use label expansion.
Application Information:
• Water Volume:
• Ground: Use a minimum water volume of 40 L per acre on oilseeds, cereals, pulses, alfalfa and grasses; use 80 L per
acre on potatoes. Ensure thorough coverage of foliage.
• Aerial: Use a minimum water volume of 20 L per acre. Ensure thorough coverage of foliage. DO NOT apply more
than 160 mL per acre by aerial application.
• Pivot or Sprinkler irrigation: DO NOT exceed 0.64 cm (1/4 inch) (63,500 L) per hectare. DO NOT apply registered
tank mixes in potato, chickpea, and canola by pivot or sprinkler irrigation. Apply only through overhead sprinkler
systems including centre pivot and lateral move containing low pressure drop nozzles.
