Which of the following is NOT affected by leaf curl virus?

Leaf curl virus primarily impacts a range of plants, particularly certain vegetables and crops that are sensitive to viral infections. In this case, peaches are not typically affected by leaf curl virus, which is more associated with other plants like tomatoes and certain legumes.

Tomatoes, for instance, are known to suffer from multiple strains of leaf curl virus, leading to significant yield losses and compromised fruit quality. Legumes, like beans, can also show susceptibility to infections by viruses that cause leaf curling and other symptoms. Cotton is another crop that can be affected by specific leaf curl viruses, contributing to decreased productivity.

In contrast, while various pathogens may affect peaches, the leaf curl virus is not among the viruses that cause significant issues in peach trees. Peach trees are more commonly associated with diseases like peach leaf curl, which is caused by a different pathogen (a fungus called Taphrina deformans) and not a virus.

This distinction is critical for effective plant disease management and helps in identifying which crops require monitoring and preventative strategies against leaf curl virus infection.
