We have a lawn fungus, and I applied Eagle to the impacted areas. 12 hrs later we got about 1.5 inches of rain over 36 hrs. Our lawn guy suggested that Headway was a better option to treat our fungus. Is it safe to apply Headway 3-4 days after the Eagle application?
You could potentially apply Headway G Fungicide Granules at this point. However, we suggest waiting at least 7 days (14 days would be better) after the last application. This is because Headway G contains propiconazole, which is in the same chemical class as the myclobutanil in the Eagle 20. Applying the same type of active ingredient too often can lead to disease resistance, so we don't want to increase that risk. We have more details on Fungicide Rotation in this article.
