Pest control using plant hormones typically aims to regulate which type of growth?

  1. Root development

  2. Flowering

  3. Bud growth

  4. Stem elongation

The correct answer is: Bud growth

Pest control using plant hormones generally focuses on regulating bud growth because certain hormones can influence the development and differentiation of buds into shoots or flowers. By manipulating hormone levels, it is possible to control how and when buds will break dormancy or develop into new growth, which can be beneficial for managing pest populations. For instance, gibberellins, a type of plant hormone, can promote bud growth and shoot elongation, while abscisic acid can inhibit bud development. Understanding this hormonal interplay allows growers to apply targeted pest control strategies that can suppress unwanted growth or enhance desirable traits, making it an essential aspect of integrated pest management in floriculture. In the context of the other growth types, while root development, flowering, and stem elongation are also influenced by plant hormones, they are not the primary focus of pest control strategies that involve growth regulation through hormonal manipulation. It is the specific control of bud growth that directly addresses how plants respond to pest pressures and environmental conditions.
