Foam formulations and apparatus for delivery

A foam mixing chamber of a system for generating and dispensing a foamed formulation by combining a gas and a liquid agricultural formulation, comprising:

• a chamber body defining an interior chamber, said interior chamber having an interior chamber inlet through which the liquid agricultural formulation enters said interior chamber and an interior chamber outlet through which the foamed formulation exits;
• a manifold head in fluid communication with said interior chamber outlet and having one or more outlet ports through which the foamed formulation exits;
• a mixing tee having a body, a tee gas inlet for receiving the gas, a tee fluid inlet for receiving the liquid agricultural formulation, and a tee outlet in fluid communication with said tee gas inlet and said tee fluid inlet, said tee outlet further being in fluid communication with said interior chamber inlet through which the gas and liquid agricultural formulation enters said interior chamber;
• and
• a foaming medium having a surface contact area and disposed within said interior chamber between said interior chamber inlet and said interior chamber outlet so that said liquid agricultural formulation passes through said foaming medium in contact with said surface area to agitate the liquid agricultural formulation, said medium having a sufficient amount of surface contact area for the desired foam expansion.

A method of generating an agricultural foam, comprising:

• (a) mixing a liquid agricultural formulation with compressed gas to create a mixture, said liquid agricultural formulation containing at least one agriculturally active ingredient;
• (b) forcing the mixture through a foaming medium having a surface contact area that is contacted by said mixture, thereby generating a foamed agricultural formulation;
• and
• (c) distributing said foamed agricultural formulation through one or more outlet ports.
