| description | Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases. In this study, the effect of two biological control organisms, Clonostachys rosea and Pseudomonas chlororaphis was examined to see if they
could reduce production of perithecia as well as sexual and asexual spores on winter wheat. Two trials were made with some minor alterations. When treated with C. rosea, the number of perithecia on wheat straws decreased in the second
trial but had no effect in the first. P. chlororaphis had no effect in either of the trials, neither did a combination of the organisms. |

En av de sjukdomar den orsakar är axfusarios. Både sexuellt och asexuellt producerade sporer av F. graminearum kan smitta plantor. De asexuella konidierna bildas i mycelet medan sexuella ascosporer bildas i asci i perithecier på halmrester. I biologisk bekämpning används levande organismer för att kontrollera skadegörare och sjukdomar. I denna studie undersöktes effekten av två biologiska bekämpningsorganismer, Clonostachys rosea och Pseudomonas chlororaphis för att se om de kan reducera produktionen av perithecier samt sexuella och asexuella sporer på halm av höstvete i två försök. C. rosea reducerade perithecieantalet i det andra försöket men inte i det första. Behandling med P. chlororaphis gav ingen effekt. Perithecieantalet minskade inte heller när en kombination av de båda organismerna tillfördes. 2014-08-27 First cycle, G2E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/7213/7/jorgensen_k_140828.pdf Jörgensen, Karolina, 2014.
