What is the Difference Between Horsetail and Marestail?

The main difference between horsetail and marestail lies in their growth habit, reproductive mechanisms, and resistance against herbicides. Here are the key differences:

1. Growth Habit: Horsetail is a perennial plant, while marestail is an annual plant.
2. Reproductive Mechanisms: Horsetail is a non-flowering plant that reproduces via spores, whereas marestail is a flowering plant that produces seeds and dense inflorescence.
3. Herbicide Resistance: Horsetail can be managed by glyphosate, while marestail is glyphosate-resistant.

Additionally, horsetail is a fern-like plant belonging to the genus Equisetum, and it is known for its medicinal value and high silica content.
