Dollar Spot Alerts

Research behind the Smith-Kerns model shows that dollar spot symptoms can be prevented if turf is treated with a solid dollar spot management program before or when the risk reaches a 20% threshold, and applications continue through the season.

Cooling Degree Day Alerts

Cooling Degree Days (CDDs) measure the accumulation of cooling below a set air temperature threshold. Research from the University of Tennessee shows that monitoring CDDs can enhance the efficacy of herbicide applications to control dallisgrass. This model begins accumulating CDDs below 72° F on August 1. Although CDD ranges may vary by herbicide selection, research shows that the ideal CDD range for fall applications to control dallisgrass is 10 – 225 CDD 72° F. Sign up below to receive email and/or text alerts when target CDD thresholds are met in your area.


Pest Specific Alerts

These alerts will help you time fall herbicide applications to control dallisgrass. Based on CDD accumulation, you will be alerted when conditions are optimal for controlling dallisgrass.


Customized Threshold Based Alerts

Select a target threshold below to receive an alert when the CDDs reach that value in your area. You may create up to five alerts. The recommended range for monitoring dallisgrass is 10 – 225 CDD 72° F. You may create up to 5 alerts:
