The flower language of Setaria viridis: patient, unknown and difficult love, which means unrequited love.

Harm of Setaria viridis

Setaria viridis, commonly known as Mao Mao dog, is one of the dominant species of weeds in orchards, with strong reproductive capacity and serious harm.

Setaria viridis will compete with agricultural products for water, nutrients and light energy: weeds have developed roots, strong ability to absorb soil water and nutrients, and strong growth advantages, and water consumption and fertilizer consumption often exceed the consumption of crop growth.

Weeds have a strong growth advantage, and their plant height is often higher than that of crops, which affects the utilization of light energy and photosynthesis of crops and interferes with and limits the growth of crops.
