Which strategy uses natural or acquired resistance to infection, and may include approaches such as tree breeding or crossprotection?

• A. Exclusion
• B. Protection
• C. Resistance
• D. Wounding and decay fungi

Answer: (C)

Using the host’s own defenses to reduce infection is the idea here. This strategy relies on natural or acquired resistance of the tree, achieved through breeding for resistant traits and approaches like cross-protection, where trees are exposed in a controlled way to induce resistance against more harmful pathogens. The goal is to enhance the tree’s ability to resist or tolerate infection rather than simply blocking entry or applying external protections. Tree breeding selects individuals with genes that confer resistance, while cross-protection leverages the plant’s induced defenses to guard against infection. This differs from exclusion, which focuses on keeping pathogens out with barriers or sanitation; protection, which involves external measures that shield the plant but don’t strengthen its own defenses; and wounding and decay fungi, which describes a disease pathway rather than a strategy to bolster host resistance.
