Post-emergent in Tribenuron Tolerant Sunflowers:
• Express SG only at 6 g per acre (one package of Express SG treats 80 acres) plus Hasten NT adjuvant at 0.5L per 100L
of spray solution will control:
º Lamb’s-quarters

†
Express SG only.
* Up to the 3 leaf stage
** Suppression only
*** Up to 6 inches
Allow 10 days between treatment and tillage.
Fall rosettes and spring seedlings.
Addition of a non-ionic surfactant at 0.2 L per 100 L of spray solution is required.
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. A general guide to mixing can be found on page 8.
Application Information:
• Water Volume: 22 to 40 L per acre.
• Nozzles and Pressure: Use appropriate pressure for nozzle. Low drift nozzles may require higher pressures for proper
performance. Use a combination of nozzles and pressure designed to deliver thorough, even coverage of ASABE
medium droplets or larger.
• Screens: Use a 50 mesh or coarser screen and filter system.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
Warm, moist growing conditions promote active weed growth and enhance the activity of tribenuron. Weeds hardened off
by environmental stress such as cold weather, drought or excessive heat may not be adequately controlled.
