I applied propiconazole 14.3 to my bermuda lawn to treat brown patch and dollar spot. I understand that these are foliar diseases, so I applied with no rain in the forecast, however it proceeded to rain within 4 hrs of application (it was warm so product had dried). Do I need to be concerned with the effectiveness of the product in treating the desired diseases after this rain?
It is recommended to water in herbicide and fungicide products like Propiconazole 14.3 because typically they need to get down to the root system, and the main way to do this is to water the lawn so the product can make its way to the roots. You can also apply more water when performing the treatment for the same effect. If you apply the product before a rain event, that is even better.
