4 Claims

1. A method of Amaranthus control, the method comprising artificially pollinating a population of plants of an Amaranthus species selected from the group consisting of A. tuberculatus and A. palmeri at a growth area with X ray irradiated pollen of said Amaranthus species, wherein said artificially pollinating is under competition conditions with wild pollen of said Amaranthus species and is done in a regimen including:

10 gram to 2 kg per acre per application during a flowering season of said Amaranthus species;

1-10 applications during a flowering season of said Amaranthus species; and/or

repeated applications spanning from daily applications to once every two months during a flowering season of said Amaranthus species, wherein said artificially pollinating is not assisted by mapping of the precise position of said population of plants of said Amaranthus species at said growth area, and wherein said regimen of artificial pollination reduces fitness of said population of plants in comparison to a control population of plants of the same species not having been artificially pollinated with said X-ray irradiated pollen.
