**9. Conclusion**

Several diseases, nematodes, weeds, and pests cause damage to strawberry foliar, roots, and fruits, and are responsible for crop losses. Numerous plant-parasitic nematodes cause damage on strawberry plants that some feed on roots, others in foliar parts. Parasitic nematodes cause yield losses, crop size, and quality. Fungal pathogens such as *Colletotrichum acutatum* and *Botrytis cinerea* are the most common pathogens in the strawberry field and may cause damage to more than 80% of strawberry

flowers and fruits. *Xanthomonas fragariae* and *X. arboricola* pv *fragariae* are important bacterial diseases of strawberries. Many pests such as *Frankliniella occidentalis* damage strawberry plants and other important pests are included in this section. Weeds are also a serious problem, and weed control is one of the biggest challenges for strawberry growers. Because strawberry plants grow relatively slowly and are weak competitors, weeds can quickly invade strawberry fields. Other important diseases are viruses and virus-like diseases that some of these viruses can cause symptoms of different severity for each race, or these disease agents can be found asymptomatically in plants. In this chapter, information about diseases, pests, weeds, and nematodes that cause yield loss in strawberry plants are brought together. Thus, it is a significant chapter for the benefit of producers, researchers, and students. It is also important to apply integrated pest management strategies to control diseases and pests in strawberry plant cultivation.
