GENERAL INFORMATION
Mesotrione 480SC Herbicide is a suspension concentrate herbicide that has soil residual activity and provides selective control or suppression of annual broadleaf weeds in field corn. Mesotrione 480SC Herbicide has a high level of crop safety to allow for flexibility in application timing in field corn.
In post-emergent applications, Mesotrione 480SC Herbicide is absorbed through the leaves and is rapidly translocated to the plant's growing points.

DIRECTIONS FOR USE
FIELD CORN – EASTERN CANADA ONLY
1.) Pre-emergent Application
Apply Mesotrione 480SC Herbicide at 0.30 L per hectare in a spray volume of 200 L and a minimum pressure of 206 kPa (refer to the “MIXING AND SPRAYING INSTRUCTIONS” section of this label).
2.) Early Post-emergent Application - Spike to 2 leaf stage of corn and cotyledon to 2 leaf stage of weeds
Apply Mesotrione 480SC Herbicide at 0.30 L per hectare in a spray volume of 200 L and a minimum pressure of 206 kPa (refer to the “MIXING AND SPRAYING INSTRUCTIONS” section of this label).
3.) Late Postemergent Application - 3 to 8 leaf stage of corn and up to 8 leaf stage of broadleaf weeds
Apply Mesotrione 480SC Herbicide at 0.21 L per hectare in a spray volume of 100- 200 L of water and a minimum pressure of 206 kPa (refer to the “MIXING AND SPRAYING INSTRUCTIONS” section of this label).
Always add a spray surfactant. Use the non-ionic surfactant AGRAL 90 at 0.20% v/v.
For best results, apply Mesotrione 480SC Herbicide to actively growing weeds. Weeds that emerge after an application of Mesotrione 480SC Herbicide will be controlled after they absorb the herbicide from the soil provided there is sufficient moisture for uptake.

GROUND APPLICATION ONLY:
Water Volume:
Apply in 100-200 litres per hectare.
Spray Pressure:
206 – 300 kPa
Spray Nozzles:
Flat Fan with 50 mesh or larger screens. For uniform coverage and increased penetration of the crop canopy, set the nozzles at a downward angle of 90 degrees (90).
Surfactant:
Postemergent applications of Mesotrione 480SC Herbicide must be applied with the non-ionic surfactant AGRAL 90 at 0.2% v/v (2.0 L for each 1000 L of spray mixture).

Mixing Procedure:
1. Ensure that the sprayer is totally clean.
2. Fill the sprayer half full with water. Engage gentle agitation.
3. Ensure that the agitation system is working properly and that it creates a rippling or rolling action on the water surface.
4. Add Mesotrione 480SC Herbicide slowly and agitate until completely dispersed. To ensure complete dispersion, wait 2 or 3 minutes after the last of the herbicide has been added to the tank.
5. Fill the tank to three quarters full with water.
6. Add the non-ionic surfactant if applicable (e.g., AGRAL 90) at 0.2% v/v.
7. Continue agitation while completing the filling of the sprayer with water.
8. Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time.
9. If agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. Mesotrione 480SC Herbicide must be sprayed the same day as mixing.
10. Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems. 

RECROPPING GUIDELINES:
Certain crops have been shown to be sensitive to low residues of Mesotrione 480SC Herbicide in the soil. The minimum recropping interval is the time between the last application of Mesotrione 480SC Herbicide and the anticipated date of planting of the next crop.
To avoid injury to subsequent crops after an application at the recommended rate of Mesotrione 480SC Herbicide, the following recropping intervals should be observed.
CROP - MINIMAL RECROPPING INTERVAL
Winter Wheat - 3 months
Spring Wheat, Field Corn (grain or silage), Seed Corn, Sweet Corn - 10 months
Alfalfa, Potato, Soybeans, Transplanted Tomato, White Beans - 11 months
All Other Crops - Bioassay
Observe the recropping guidelines of any product(s) to be tank mixed with Mesotrione 480SC Herbicide.
In the event of crop failure, only field corn (grain or silage), seed corn, or sweet corn can be planted as a salvage crop in the same fields in which the failed crop was treated with Mesotrione 480SC Herbicide. An application of Mesotrione 480SC Herbicide must NOT be made to the salvage crop.
Land treated with Mesotrione 480SC Herbicide CAN ONLY BE PLANTED TO A CROP NOT LISTED IN THE PREVIOUS TABLE if a field bioassay can be successfully performed. The bioassay must indicate normal growth with no yield reductions.
A bioassay may be conducted in any year following the year of application to assess the tolerance of the tested crop intended for planting in the year following the bioassay. Do not conduct a bioassay in the year of application. When conducting a field bioassay, it is very important to select a representative area(s) of the field previously treated with Mesotrione 480SC Herbicide to plant the test crop(s). 
FIELD BIOASSAY
1. Representative Sample:
Ensure that soil parameters such as soil texture, depth of topsoil layer, soil pH and drainage of the test area selected are representative of the remainder of the field.
2. Sample Size:
The seeded area of each selected bioassay crop must be large enough to ensure that reliable results are obtained. The seedbed preparations and seeding of the bioassay crop(s) should be conducted the same way as when the entire field would be planted.
3. Other Residual Herbicides:
It is important that other herbicide products which are known to have residual activity were not applied to the field between the last application of Mesotrione 480SC Herbicide and the bioassay testing period. Avoid the use of other pesticides during the duration of the bioassay as they may damage the indicator crop(s).
4. Comparisons:
Ideally, an untreated check strip in a neighbouring field should be established and monitored for comparison since growing conditions can vary greatly from year to year and may result in erroneous results.
5. Assessment:
The site should be monitored regularly throughout the growing season. Watch for any damage to the crop such as thinning, yellowing or stunting. A yield sample should be taken and compared to an adjacent untreated field.

DO NOT ROTATE TO OTHER CROPS UNTIL THE BIOASSAY INDICATES NORMAL GROWTH WITH NO YIELD REDUCTIONS.
Failure to follow these recropping guidelines could result in injury to seeded crop(s).
