One major complication to the use of herbicides for weed control is the ability of plants to evolve herbicide resistance, rendering the herbicides ineffective against target plants. Out of 31 known herbicide modes of action, weeds have evolved resistance to 21. 268 plant species are known to have evolved herbicide resistance at least once. [ 59 ]
Floral diagram of Ranunculus acris.The light green ovals denote nectaries. Ranunculus acris is a herbaceous perennial plant that grows to a height of 30 to 100 cm, with ungrooved flowing stems bearing glossy yellow flowers about 25 mm across.
