5. Diseases and Pests
Root rot and asparagus crown are disastrous diseases that affect asparagus crops throughout the world. Crown rot is caused by three types of Fusarium. They are fusarium moniliform, Fusarium proliferatum, and Fusarium oxysporum. All three types of fungi can invade the roots of the asparagus. The fungi can also invade the tissue of the plant that carries nutrients and water from the root of the plant to throughout the stem and the leaves.
When a crop of asparagus is infected by one of these diseases you will notice that the plants start to rapidly die off. The crowns will start to turn yellow and begin to wilt. Once this occurs, the plants will become rotten and then you will see the plants start to die. You need to make sure that you are diligent in keeping your asparagus healthy.
Proper weeding, making sure the soil has the right pH balance and keeping it well watered can help to ensure that your plants remain disease-free.
