Amaranth weed species have an extended period of germination, rapid growth, and high rates of seed production, [3] and have been causing problems for farmers since the mid-1990s.

Weed-wiping may also be used, where a wick wetted with herbicide is suspended from a boom and dragged or rolled across the tops of the taller weed plants. This allows treatment of taller grassland weeds by direct contact without affecting related but desirable shorter plants in the grassland sward beneath. The method has the benefit of avoiding ...
