摘要

Method and apparatus for combating pests in and on fruit - and treatment of wood trees. The present invention describes a gas-operated conveying device for a pourable pest control agents, in the hydrogen gas evolution cells in a time amount which is determined by the electric current. In this case, the conveying device in fig. 1 a cylindrical space 1, which is closed off by a cover 2 and of the gas holder 3 and a piston 4 contains. The piston divides the cylindrical space in a first partial chamber for receiving the pest control by means of and in a second partial chamber, into which the propellant gas, the gas evolution cells emit. The pest control agent is directly into the feed means circle running of the tree is emitted.
