For instance, if I have applied Heritage G twice this season at the recommended rate of 2lbs/1000 sq ft, should I switch to a fungicide in a different group if I need to apply fungicide again this season. Or can I apply Heritage G again?
Typically rotating fungicides after 2-3 applications is recommended to prevent resistance. The days between applications and number of sequential treatments recommended is based off the product label of each fungicide. Please view our article A Beginner's Guide to Fungicides. for more information.
