treated area. DO NOT apply to soils that are permeable, have sinkholes, or lie over limestone bedrock. DO NOT apply to
soils whose surfaces are composed of fractured rock or unconsolidated gravel. Application to these sites may allow the
movement of herbicide to underlying water sources or aquifers. When applying Grazon XC over sandy soils ensure that
aquifers are not within 1.8 m of the soil surface. If shallow aquifers are present, DO NOT APPLY Grazon XC. Grazon XC
must not be applied on range and pasture acres that are irrigated. DO NOT compost or mulch clippings or manure from
grass treated with Grazon XC unless being reapplied to the treated area.
Effects of Growing Conditions:
Nothing listed on the Grazon XC label. Avoid application when pasture and target weeds are under stress from drought,
flooding, extreme heat or cold, as injury to grass or unacceptable control may result. Avoid application when temperatures
exceed 28°C.
Tank Mixes:
None registered.
Restrictions:
• Rainfall: DO NOT apply if rainfall is forecast. No specific time frame is indicated on the label. Contact manufacturer for
more information.
• Re-entry Interval: DO NOT re-enter pastures within 3 days of application.
• Grazing Restrictions: DO NOT allow lactating dairy animals to graze treated areas within 7 days of application.
Withdraw meat animals from treated fields at least 3 days before slaughter. DO NOT harvest forage or cut hay within
30 days of application. Feed livestock untreated forage for 7 days prior to moving onto land that produce broadleaf
crops; otherwise, urine or manure may contain picloram. See restrictions in “How it Works” section above.
• Re-cropping Interval: Legumes may not be established in a pasture for several years after treatment. If legumes are
essential in a pasture, DO NOT use Grazon XC. DO NOT break up treated pasture and plant to sensitive broadleaf crops
for at least 5 years after application.
• Aerial Application: May be applied by air.
• Storage: Store product in original containers in a secure, dry, cool area. DO NOT freeze.

* These distances can be reduced by 30% using cones on individual nozzles and by 70% using a full shield
(shroud, curtain) that extends to the crop canopy.

Distance measured as metres from the downwind edge of the spray boom to sensitive habitat. Refer to the label
for buffer zone requirements for aerial application.
º Heavy rains can move this product from its application site down slope toward sensitive areas. DO NOT load or mix
near wells, dugouts or other water bodies.

Sprayer Cleaning:
There are no sprayer cleaning recommendations on the product label. A combination of Method A and B found on the
general page on sprayer cleaning on page 9 and 10, or the use of a commercial tank cleaner, completed immediately after
application is finished may be the best cleanout option.
Hazard Rating:
Caution – Poison
May cause skin and eye irritation
