Blackhawk may degrade if left in the sprayer for an extended period under alkaline conditions. Apply within 24 hours of
mixing.
Application Information:
• Water Volume: Minimum 20 L per acre up to 40 L per acre (recommended).
• Nozzles and Pressure: Flat fan nozzles operated at a pressure of 30 to 40psi (210 to 275 kPa) are recommended. Use
nozzles and pressure designed to deliver thorough, even coverage with ASABE medium droplets. Boom height must
be 60 cm or less above the crop or ground.
• Screens: Use 50 mesh or coarser on both nozzle and primary plumbing screens.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
Control may be reduced if weeds are under stress (e.g. drought, heat or cold stress). Weeds hardened off by cold weather or
drought may not be adequately controlled or suppressed.
Tank Mixes:
Herbicides:
Pre-seed and Pre-emergent:
• Glyphosate (180 to 360 g ae per acre) (no surfactant required)
Note: The above mixes are those listed on the Blackhawk label only. Nufarm Agriculture also supports the following
mixes that are not on the Blackhawk label.
• Herbicides:
º In fall: Valtera (spring seeded chickpea, field pea, soybean, spring wheat)
º In spring: Valtera (soybean only)
Adding ingredients in the correct order is critical for optimum performance. Check labels of products to be mixed for
directions. General guidelines can be found on page 8.
