Which is an advantage of soil injectors?

• A. Minimal drift
• B. Watering after application is required
• C. High amounts of insecticide needed per tree
• D. Difficult to treat root zones near roadsides

Answer: (A)

Soil injection puts the pesticide directly into the root zone rather than spraying it into the air or onto foliage. The biggest benefit of this method is that it minimizes drift because the active ingredient is placed in the soil, not dispersed by wind. That means less off-target movement and exposure to unintended plants, people, or beneficial insects, while still delivering the chemical right where the roots can take it up. Watering after application isn’t an inherent advantage of soil injectors; in some cases irrigation helps move the product into the root zone, but it’s not what makes soil injection advantageous. Also, using large amounts per tree isn't a goal of this method, and root-zone treatments near roadsides aren’t inherently easier with soil injectors.
