Weed Control
Rate:
Signal F: 0.2 L per acre
Boost: 8 g per acre
Enhance Adjuvant: 0.25 L per 100 L of total spray solution.
(One package treats 40 acres)
Maximum one application per year of Signal FSU or other products containing clodinafop, thifensulfuron, tribenuron, or
fluroxypyr.
Thifensulfuron/tribenuron may degrade if left in the sprayer for an extended period. Apply within 24 hours of mixing. Refer
to the product label for complete mixing instructions.
Application Information:
• Water Volume: Minimum 40 L per acre.
• Nozzles and Pressure: Use 29 to 40 psi (200 to 275 kPa) if applying without drift reduction nozzles. Drift reduction
nozzles may require higher pressures for proper performance. Select the nozzle and pressure combination that
produces of ASABE coarse droplets while maintaining good coverage of foliage. Keep booms lower than 60 cm from
crop canopy.
• Screens: Use of 50 mesh screens or coarser are required.
