• Shelterbelts:
º Princep Nine-T: 1.8 kg per acre.
º Simazine 480: 3.8 to 5.7 L per acre.
* Rate of application to corn is dependent on soil texture. Refer to specific labels for correct application
rates on corn.
Application Information:
• Water Volume: Minimum 121 L per acre. In shelterbelts, use a minimum of 202 L per acre.
• Nozzles and Pressure: For conventional flat fan nozzles use a maximum pressure of 30 to 45 psi (200 to 300 kPa).
Low drift nozzles may require higher pressures for proper performance. Use a combination of nozzles and pressure
designed to deliver thorough, even coverage with ASABE medium droplets.
• Screens: Use 50 mesh or coarser nozzle screens and filter system.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
When applying to forage stands, dry soil conditions at the time of weed emergence may result in reduced weed control.
Tank Mixes:
None registered.
Note: The above mixes are those listed on the simazine labels only.
Adding ingredients in the correct order is critical for optimum performance. Check labels of both products to be mixed for
directions. General guidelines can be found on page 8.
Restrictions:
• Rainfall: Moderate rainfall after application enhances activity.
• Re-entry Interval: DO NOT enter treated areas for 12 hours following application.
• Grazing Restrictions: In forage stands, allow 30 days between application and grazing, 60 days between application
and cutting for feed. DO NOT graze or cut corn for feed prior to ear emergence.
• Re-cropping Interval: Simazine is persistent and residues may persist for several years depending on soil pH, available
soil moisture, number of yearly applications, and the sensitivity of the following crop. Simazine will break down in soil
more slowly under conditions of high pH and/or low rainfall. Corn will tolerate soil residues of simazine and may be
planted the year of application. Navy beans, onions, peas may be injured 12 month after application.
• Aerial Application: DO NOT apply by air.
• Storage: DO NOT freeze Simazine 480. Princep Nine-T may be frozen. Store in a cool, dry place.
• Buffer Zones:

* Buffer zones can be reduced by 70% when using shrouds and by 30% when using cones mounted less than
12 inches from the crop canopy.
