How does increasing pest pressure affect horticulture?

Increasing pest pressure has a significant impact on horticulture primarily through its ability to decrease crop yields. When pest populations rise, they can cause direct damage to plants by feeding on leaves, stems, roots, and flowers, which can hinder plant growth and development. This can lead to reduced photosynthesis and nutrient uptake, negatively affecting the overall vigor of the plant.

Additionally, pests can introduce diseases and act as vectors for pathogens, further stressing the plants and leading to lower productivity. As crop yields decrease, this not only affects the quantity of produce but also can result in poor quality of fruits or vegetables, making them less marketable. Therefore, effective pest management becomes crucial for maintaining healthy crops and achieving optimal yields in horticultural practices.

Other options, such as having no economic impact or simplifying management practices, are misleading because increased pest pressure typically complicates management and can result in economic losses for growers due to decreased yields and quality. Similarly, pests do not ensure healthier plants; rather, their presence often leads to stress and potential decline in plant health.
