What is implanted into trees during implantation?

• A. Oil-based capsules
• B. Water-soluble capsules
• C. Solid granules
• D. Gas cartridges

Answer: (B)

Implantation aims to deliver a pesticide systemically through the tree so the chemical travels with the sap to all parts of the tree. Water-soluble capsules are best for this because they readily dissolve in the tree’s moving sap after insertion, releasing the active ingredient and allowing it to move through the xylem to support the whole tree. Oil-based capsules tend to stay oily and may not dissolve or distribute as well, which can limit uptake. Solid granules are too large to move smoothly in the sap and can clog vessels. Gas cartridges don’t provide a liquid phase to carry the pesticide through the tree. So, water-soluble capsules fit the method and purpose of implantation most effectively.
