Abstract: A method of producing pollen that reduces fitness of at least one weed species of interest is provided. The method comprises treating the pollen of plants of a weed species of interest with an irradiation regimen selected from the group consisting of: (i) X-ray radiation at an irradiation dose of 10-1600 Gy; (ii) gamma radiation at an irradiation dose of 10-2000 Gy; (iii) particle radiation; and (iv) UV-C radiation at an irradiation dose of 100 ?J/cm2-50 J/cm2, with the proviso that when said weed is A. palmeri, when said irradiation is X-ray, the irradiation dose is not 300 Gy and wherein when said irradiation is gamma irradiation the irradiation dose is not 100, 300 and 500 Gy, and wherein when said radiation is UV-C the dose radiation is not 2 J/cm2.

Abstract: Methods of Amaranthus control are provided, comprising, artificially pollinating an Amaranthus species at a growth area with an effective amount of pollen that reduces fitness of the at least one Amaranthus species, the effective amount comprising 1 mg to 1 gram per plant per application using a precision tool-assisted application or 10 gram to 100 kg per acre per application using a non-precision tool-assisted application during a flowering season of the Amaranthus species.
