Begin applications when conditions are favourable for disease infection and/or prior to disease symptom expression. Under conditions of high disease pressure, use the shortest retreatment interval.

Application intervals:

Anthracnose, Microdochium patch or red thread: 14 days
Brown patch or dollar spot: 14-21 days

Mixing Order:

WALES Symbol: S

  1. Fill the spray tank one-half to two-thirds full with clean water and begin agitation.
  2. Add the required amount of Ascernity™ to the tank, allowing time for good dispersion.
  3. Finish filling the tank to the desired volume to obtain the proper spray concentration.
  4. Maintain agitation throughout the spraying operation.
  5. Do not allow spray mixture to stand overnight or for prolonged periods.

Make up only the amount of spray required for immediate use. Sprayers should be calibrated before application and thoroughly cleaned immediately after application.

Use Restrictions:

  • Do not use silicone-based products with Ascernity™ fungicide due to possible phytotoxicity.
  • Do not apply more than 62 mL product/100 m2/year (6.2 L product/ha/year) on turfgrass.
  • Do not apply more than two sequential applications of Ascernity™ fungicide (Group 3 and Group 7 fungicides) before alternating with a fungicide having a different mode of action registered for the same disease.
