  • Patent number: 9549499
    Abstract: A solid carrier sprayer apparatus, including a solid carrier container, a liquid container, a solid carrier spreading apparatus, and a liquid application apparatus is provided. The solid carrier spreading apparatus can be coupled to receive solid carrier from the solid carrier container, and is configured to drop the received solid carrier substantially evenly over an area of ground. The liquid application apparatus can be coupled to receive liquid from the liquid container, and is configured to spray received liquid substantially evenly over the received solid carrier, such that the liquid is sprayed substantially evenly over the received solid carrier before the solid carrier is dropped substantially evenly over the area of ground. Methods of using a solid carrier sprayer apparatus are also discussed.

  • Patent number: 6022828
    Abstract: A method for controlling Poa trivialis using a bacterium which is a Xanthomonas campestris pathovar which produces a wilt in the weed grass is described. In particular, the use of a Xanthomonas campestris which infects the Poa trivialis types to suppress or kill this weed grass is described. The method allows non-weedy grasses to develop without interference from Poa trivialis to improve lawns, golf courses and the like.
