1. A method of inhibiting growth of a plurality of plants of a weed species of interest being Amaranthus palmeri or Alopecurus myosuroides in a growth area, the method comprising, artificially pollinating inflorescences of said plants with irradiated pollen that reduces fitness of said plants, said artificially pollinating is performed under pollination conditions that inhibit growth of the plants wherein said conditions comprise:
(i) at least 20% of the plants in the growth area are flowering female plants having more than 1 spike per plant longer than 4 cm; and
(ii) competition with native pollination,
wherein said inhibiting growth is manifested by a reduced vegetative biomass of the plurality of plants as compared to control plants of said weed species of interest not treated with said pollen, being in the same growth conditions and harvesting time from germination.
