Which of the following actions typically inhibits plant growth?

The application of herbicides is typically designed to inhibit plant growth, particularly targeting unwanted weeds. Herbicides contain chemical compounds specifically formulated to disrupt various biological processes in plants, leading to their decreased growth or death. These chemicals can interfere with the photosynthesis, nutrient uptake, or hormonal balance of the targeted plants, effectively controlling or eliminating them from the area.

The other actions, when executed properly, support plant health and growth rather than inhibit it. Watering provides essential moisture which is crucial for plant survival and growth. Weed removal helps reduce competition for resources such as light, water, and nutrients, allowing desired plants to thrive. Soil aeration improves air circulation, enhances root development, and facilitates the absorption of water and nutrients, all of which are beneficial for plant growth.
