US Patent:
5174807, Dec 29, 1992
Filed:
Mar 15, 1991
Appl. No.:
7/670318
Inventors:
Christopher N. MacDonald - Kailua HI
International Classification:
A01N 5704
US Classification:

Abstract:
A method of eradicating plants on an inaccessible terrain by selecting hollow balls formed by a frangible membrane, filling such balls with respective charges of herbicide fluid of the type to which such plants are susceptible to provide a supply of such charged balls. Selecting a repeater ball firing gun of the type incorporating a mechanism having sufficient propulsion to transmit a certain minimum muzzle velocity to such balls in a repetitive manner, transporting such gun by helicopter to hover over such terrain. Shooting a quantity of such balls at each plant from a range sufficiently close to cause the skins of such balls to be ruptured upon impact to thereby splash herbicide on the respective plants.
