Washington Agricultural and Right-of-Way Pesticide Practice Test

Question: 1 / 400

What is the primary goal of regular mowing when dealing with weed issues?

To increase the height of the grass

To weaken the root systems of perennial weeds

Regular mowing primarily aims to weaken the root systems of perennial weeds. By consistently cutting off the tops of these weeds before they can flower and produce seeds, mowing disrupts their ability to store energy and nutrients in their roots. This method reduces their vigor over time, making it more challenging for them to survive and thrive. In effect, regular mowing lowers the overall population of perennial weeds in an area, as it prevents them from establishing a strong hold and spreading further.

While some other practices can help enhance grass growth or stabilize soil structure, these do not directly target the primary goal of managing weed populations like regular mowing does. The focus on weakening the roots of perennial weeds is essential for effective weed management in agricultural and landscape settings.
