Application Method

Ground

Application Information

Field Corn, Seed Corn, Sweet Corn

  • Nitrogen solutions (such as 28-0-0 UAN), excluding suspension fertilizers, may replace water as a carrier for pre-emergence application in corn.
  • When making a post-emergent application always add Agral 90 at 0.2% v/v. (2L/1000L spray mix)
     

Blueberries

  • Lowbush – Make a broadcast application over the top of the blueberries
  • Highbush – Make a broadcast application directed to the base of the plant
  • Callisto can be applied up to the pre-bloom stage of the crop. Time application according to the stage of the weeds from pre-emergence to 8-leaf stage of the weeds.
  • When making a post-emergent application always add Agral 90 at 0.2% v/v. (2L/1000L spray mix)

Other crops – check the label.

Mixing Order

  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. If required, add Ultim or Accent slowly and agitate until completely dispersed.
  5. Add Callisto 480SC and Primextra II Magnum or Aatrex® Liquid 480 herbicide (if an applicable tank-mix) 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.
  6. Fill the tank to three quarters full with water.
  7. Add Dual II Magnum® if required.
  8. Add Touchdown® iQ, Touchdown Total®, Roundup WeatherMAX®, Roundup® Original, Roundup Transorb®, Glyfos®, Credit® Plus, Vantage™, Vantage™ Plus, or Renegade® if required. Refer to the label of the tank mix partner and the surfactant for the specific mixing instructions.
  9. Add the non-ionic surfactant if applicable (e.g., Agral 90) at 0.2% v/v.
  10. Continue agitation while completing the filling of the sprayer with water.
  11. Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time.
  12. If agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. Callisto 480SC must be sprayed the same day as mixing.
  13. Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems.

Effects of Weather

  • In pre-emergent applications, rain is required within 10 days or a shallow cultivation or use of a rotary hoe is necessary.
  • Typically 4/10th to ½ inch of rain in one or two rain events soon after application is sufficient for weed control.
  • Dry weather conditions as well as excessive rainfall or irrigation following application may reduce weed control.

Use Restrictions

  • Do not apply by air.
  • Make only one application per year.

Crop Safety

As mesotrione is a selective herbicide, it affects corn plants differently than weeds. Corn's tolerance to mesotrione is excellent, primarily due to the rapid breakdown of the herbicide into inactive metabolites. Thus, corn has the ability to metabolize mesotrione much quicker than the target weeds.

Technical Information

Chemistry Group

Group 27 herbicide

Mode of Action

Callisto contains the active ingredient Mesotrione.  Once absorbed by the target weed, mesotrione quickly moves to its site of action in the cytoplasm of the chloroplasts. Mesotrione inhibits an essential plant enzyme called HPPD (p-hydroxyphenyl pyruvate dioxygenase) that is found primarily in the cytoplasm of the chloroplasts.

Disruption of pigment synthesis causes bleaching symptoms in susceptible plants that leads to necrosis and plant death. Visible symptoms of weed injury include bleaching of foliage and growing points.

Typically, following a post-emergent application, visual symptoms appear 3-5 days after application with weed death occurring within 2-3 weeks. However, weeds stop competing with the crop soon after application.

Resistance Management

Callisto is a group 27 herbicide. Do not use another group 27 herbicide in the same field in the same year.

Crop Rotation

The following re-cropping intervals should be observed:

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 re-cropping guidelines of any product(s) to be tank mixed with Callisto 480SC herbicide.
