Which cultural management strategy is intended to reduce insect damage by promoting root growth and plant vigor?

• A. Select grasses for site and use
• B. Choose endophytic grasses
• C. Encourage rooting
• D. Reduce drought, heat, and other abiotic stresses

Answer: (C)

Encouraging rooting strengthens the plant’s ability to take up water and nutrients, supporting a vigorous, healthy growth habit. When roots are well developed, the plant can better tolerate and recover from insect damage because it has more energy reserves and stronger nutrition to repair tissue after feeding. A robust plant tends to resist or outgrow pest injury, reducing the overall impact of insects. So this strategy directly targets root development to boost vigor and resilience, making it the best fit for lowering insect damage. Other options offer benefits through different mechanisms—selecting grasses for the site matches conditions, endophytic grasses rely on chemical defenses, and reducing abiotic stresses helps health but isn’t specifically about promoting root growth.
