What is it about?
This study was conducted to estimate Fusarium head blight (FHB) and crown rot (FCR) disease incidence on wheat and their interaction with cultural methods (cultivar types, planting time, seed rate, crop rotation, and fertilizer practices) that are used in wheat cropping system in the south of Iraq, Basra province. The results verified that most of the agricultural practices examined in this study were associated with positive correlation for FHB and FCR in the occurrence of disease incidence. Except the cultivar type and fertilizer application had unclear relationship with the incidence of both diseases.

Why is it important?
This study was conducted for the first time in Iraq to estimate FHB and FCR disease incidence on wheat by calculating infected plant parts (root, crown, stem, and head) at symptom occurrence, evaluate the cultural methods that promote causal agents to cause these diseases, and also to assess the management practices of fungi that were used during the search time.
Perspectives
Using effective crop rotation, such as legumes associated with the recommended planting date, seeding rate, fertilizer applications, and soil properties that are related to the suppression of soil-borne pathogens, could help in reducing the inoculum of Fusarium species that cause FHB and FCR on wheat crop in Basra province. The consequence of nitrogen and other nutrient applications may also to some extent affect the establishment of encouraging conditions for both diseases in wheat fields. The seven wheat cultivars examined in this study were shown obvious symptoms for both diseases, but the level of susceptibility varied among these cultivars. There are another seven wheat cultivars (Al-Fatih, Tammuz 2, Latifiah, Baraka, Ebaa 95, and Research 10) grown in the studied areas; therefore, extensive investigates on all growing cultivars should be executed considering the resistance levels against Fusarium pathogens, potential yield losses, and identifying mycotoxin levels and their produces.
