What are soil injectors used to do?

• A. Put systemic pesticides into the root zone of trees and shrubs
• B. Apply foliar sprays to leaves
• C. Inject pesticides into irrigation water
• D. Treat soil surface only

Answer: (A)

Soil injectors deliver pesticides directly into the soil around the plant’s roots, so the roots take up the chemical and it moves systemically through the plant. This targets pests that feed in the root zone or within the plant once the chemical is distributed, providing protection from the inside rather than on the surface or on leaves. It’s different from foliar spraying, which applies pesticides to leaves; or from injecting into irrigation water (a different method called chemigation); or from surface-only treatments that stay on the soil surface.
