BEST ANSWER: Make surface or subsurface applications using conventional spray equipment. Use
weighted trailing hoses to apply this product near the surface of the hydrosoil. Make
applications with a spray volume of 5 to 100 gallons per acre. So it will depend on how you are planning on applying the product.
