Application would be done using end hose method. Thanks
Bifen IT typically only take 1 hour to completely dry on a surface and will hold up very well in the rain, but you should have a minimum of 6 hours between your applicaton and rainfall or irrigation. Bifen IT is rainfast 6 hours after the application, and is recommended to be used with a pump sprayer.
