Which pest is commonly known to affect nursery stock?

Aphids are indeed one of the most common pests affecting nursery stock. These small, sap-sucking insects can significantly impact plant health by feeding on the phloem, which can lead to stunted growth, wilting, and even death of the plants if not controlled. They are particularly problematic because they reproduce quickly, and their populations can grow rapidly under favorable conditions.

Additionally, aphids are known vectors for plant viruses, which can further complicate management and lead to more severe outbreaks in nursery settings. Their presence can be seen on a wide variety of plants, making them a pervasive issue in nurseries that cultivate diverse species.

While other pests like spider mites, whiteflies, and thrips are also threats to nursery stock, aphids are particularly notorious for their widespread occurrence and the extensive damage they can cause, making them a priority for management in nursery environments.
