WARNING: APPLY CALLISTO GT HERBICIDE ON GLYPHOSATE TOLERANT CORN VARIETIES ONLY

Application timing – 3- to 8-leaf stage of glyphosate tolerant corn
Product rate – 2.25 L/ha
Application method – Ground application only
Restricted entry interval (REI) – 12 hours
Notes:
1. Add a non-ionic spray surfactant, such as AGRAL 90, at a rate of 0.2% v/v.
2. Apply in a spray volume of 100-200 L.
3. One application per year.

Pre-harvest intervals:
Crops – PHI (days):
Field corn grain / stover – 100;
Field corn forage – 90.
For best results, apply CALLISTO GT Herbicide to actively growing weeds. Weeds that emerge after an application of CALLISTO GT Herbicide will be controlled after they absorb the herbicide from the soil provided there is sufficient moisture for uptake.

CALLISTO GT Herbicide will provide burndown control of:
Emerged (1) Weed Control of Broadleaf Weeds:
Mustard (wild); Buckwheat (wild); Canola (non-glyphosate tolerant); Chickweed; Cleavers; Cocklebur; Corn Spurry; Cow cockle; Eastern black nightshade; Flixweed; Hawk’s beard (narrow-leaved); Hempnettle; Lamb’s-quarters; Night Flowering Catchfly; Kochia; Lady’s thumb; Milkweed (common) (2, 4) Mustard (wild); Pigweed (redroot, smooth); Ragweed (common); Shepherd’s purse; Smartweed (green, Pennsylvania); Sowthistle (perennial) (3); Stinkweed; Stork’s bill; Tomato (wild); Thistle (Russian); Thistle (Canada) (3); Velvetleaf; Wirestem muhly (4).
Emerged (1) Weed Control of Grasses: Barley (volunteer); Barnyard Grass; Crabgrass (smooth, hairy); Fall Panicum; Foxtail (green, yellow, giant); Quackgrass; Proso Millet (wild); Wheat (volunteer); Wild Oats; Yellow nutsedge (2, 4).
(1) Plants not fully emerged at time of application will not be controlled. Weeds will be more easily controlled, and early competition avoided, with applications made when weeds are small. Control of weeds greater than 25 cm in height will be inconsistent, although some weeds may be controlled.
(2) Suppression Only.
(3) Perennial sowthistle and Canada thistle should be from the rosette stage to 20 cm in height and actively growing.
(4) Wirestem muhly should be 10-20 cm in height and actively growing. Common milkweed should be 15 – 60 cm in height and actively growing. Yellow nutsedge should be 5 – 15 cm in height and actively growing.


GROUND APPLICATION. It is important to check the physical compatibility of tank mixed pesticide products in a small volume prior to filling the sprayer. Check the compatibility of tank mixes containing CALLISTO GT Herbicide using a jar test with proportionate amounts of mix partners, and water, before mixing in the spray tank.


MIXING INSTRUCTIONS
:
1. Ensure that the sprayer interior is clean, then fill the spray tank with 1/2 the required amount of water and engage agitation. Good agitation is indicated by a rippling or rolling action on the surface of the water.
2. Add any WG or DF formulation mix partners and agitate to ensure complete mixing.
3. Add CALLISTO GT Herbicide and agitate to ensure complete mixing.
4. Add any SE or SC formulation mix partners and agitate to ensure complete mixing.
5. Add any EC formulation mix partners and agitate to ensure complete mixing.
6. Fill the tank to 3/4 the required amount of water.
7. Add any solution (SN or SL) formulation mix partners and agitate to ensure complete mixing.
8. Add non-ionic surfactant (NIS). For example, AGRAL 90 at 0.2% v/v.
9. Finish filling the sprayer with water, maintaining good agitation.
10. After any break in spraying operations, agitate thoroughly before spraying again.
11. Spray the pesticide suspension the same day as mixing.
12. Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems.
When using chemical handling equipment to fill the sprayer, the following additional recommendations apply:
WG and DF formulations are preferentially batch mixed.
SC, SN, and SL formulations may be inducted or batch mixed.
EC formulations are preferentially batch mixed.

Sprayer clean-up:
Before Spraying:
Prior to using CALLISTO GT Herbicide, ensure that the spray tank, lines and filter are thoroughly clean.
After Spraying:
Thoroughly clean application equipment immediately after spraying. DO NOT allow CALLISTO GT Herbicide residue to dry within the spray tank.
When using tank mixes, consult the tank-mix partner label for additional clean-up instructions.
The following recommendations are provided:
1. Drain and flush tank walls, boom and all hoses for ten minutes with a clean water/detergent mixture. Rinse with clean water. DO NOT clean the sprayer near desirable vegetation, wells or other water sources.
2. Remove all nozzles and screens and wash separately.
3. Dispose of all rinsate in accordance with provincial regulations.


EQUIPMENT SPECIFIC INSTRUCTIONS
Field sprayer application: DO NOT apply during atmospheric conditions of thermal inversion which are characterized by dead calm. Avoid application of this product when winds are gusty. DO NOT apply spray droplets which are smaller than the American Society of Agricultural and Biological Engineers medium (classification ASABE Standard S-572.1). Boom height must be 60 cm or less above the crop or ground.


SPRAYING INSTRUCTIONS:
1. Water Volume: Apply in a minimum spray volume of 100 L/ha OR the volume given in the crop and pest specific instructions tabulated below, whichever is LARGER.
2. Sprayer Agitation: Use a jet agitator or liquid sparge tube which recirculates 10% or more of the tank per minute. DO NOT use an air sparger.
3. Pump: Screens should be used to protect the pump and prevent clogging. Use 16 mesh or coarser screens on the suction side of the pump. DO NOT place a screen in the recirculation line. Use 50 mesh or coarser screens between the pump and boom.
4. Spray Nozzles: 80 or 110 drift reducing flat fan (e.g. those with a pre-orifice or turbulence chamber) or air induction nozzles are recommended. Use 50 mesh nozzle screens. DO NOT use flood type nozzles, controlled droplet application equipment, spray foils or hollow cone nozzles.
5. Pressure: As recommended by the nozzle manufacturer to achieve ASABE medium sized droplets.
6. Apply at uniform speed and avoid overlapping. Shut off spray boom while starting, turning, slowing or stopping to avoid potential crop injury from over application.
Coarse sprays are less likely to drift, therefore, avoid combinations of pressure and nozzle type that will result in fine particles (mist). DO NOT apply during periods of dead calm or when wind velocity and direction pose a risk of spray drift. DO NOT spray when the wind is blowing towards a nearby sensitive crop, garden, terrestrial habitat (such as shelter-belt) or aquatic habitat.

AERIAL APPLICATION. DO NOT
apply by air.


MIXING AND SPRAYING INSTRUCTIONS:
The use of urea ammonium nitrate (UAN) will result in crop injury and reduced grass weed control and is not recommended with CALLISTO GT Herbicide.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) medium classification. Boom height must be 60 cm or less above the crop or ground.
DO NOT apply by air.


BUFFER ZONES.
Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer and spot treatment.
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, riparian areas and shrublands), sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.
Method of application - Field sprayer.
Crop - Glyphosate tolerant corn.
Buffer zone (metres) required for the protection of:
Aquatic habitat – 1
Terrestrial habitat – 4
NOTE: Applicators may recalculate a site-specific buffer zone for field applications by combining information on current weather conditions and sprayer configuration. To access the Buffer Zone Calculator, please visit the Pest Management Regulatory Agency web site. See Drift Mitigation under Growers and Commercial Users.
For tank mixes, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture and apply using the coarsest spray (ASAE) category indicated on the labels for those tank mix partners.
