  • Method and apparatus for applying a growth regulating composition to a cotton crop
    Patent number: 6594950
    Abstract: A wick applicator for applying agricultural liquid chemicals to crops, weeds and other vegetation. The wick applicator includes an elongated tube for holding and dispensing liquid chemicals. An air inlet extends from the tube and is communicatively open to the internal chamber of the tube. To meter or regulate the flow of liquid chemicals from the elongated tube, a non-variable fixed size orifice is disposed in the air inlet tube. In use, the wick applicator is useful in applying a growth regulating composition to the upper portion of a cotton crop. This is achieved by setting the wick applicator at a selected height and then moving it through a cotton field at that height and in the process, engaging and mopping the portion of any cotton crop in its path.
