Which description best defines a weed management plan in nurseries?

• A. A plan using cultural, mechanical, and chemical controls
• B. A plan using cultural and chemical controls only
• C. A plan that eliminates the use of any weed control
• D. A plan focusing exclusively on mechanical removal

Answer: (B)

Weed management in nurseries is best described as a plan that uses cultural controls along with chemical controls. Cultural controls change the growing environment to discourage weeds and reduce their establishment—practicing sanitation to remove weed sources, using weed-free media and mulches to shade the soil, and managing irrigation and crop spacing so the canopy suppresses weed germination and growth. Chemical controls complement these measures by providing herbicides that prevent seeds from germinating (pre-emergents) and those that control weeds that do appear (post-emergents), selected to be safe for the nursery crops and used with resistance management in mind. This combination covers prevention and suppression in a practical, effective way, and it avoids relying on mechanical removal alone or on neglecting weed control altogether.
