- Description
Durum wheat (Triticum durum) is the second most produced and marketed wheat species after wheat (Triticum aestivum L.) and, as other cereals, can be infected by a variety of fungal pathogens including Fusarium graminearum Schwabe. Chemical control has proved to be efficient but because its use is increasingly conditioned by the different regulatory bodies it is important to seek control alternatives such as use of suppressive compost and biological control agents. This study tuned up the necessary conditions to generate root rot caused by F. graminearum. The medium N?hrstoffarmer Spezieller (SNA) was better than carnation leaf agar (CLA) to reach high macroconidia concentration necessary to obtain plant disease. Both liquid and soil inoculum was effective to produce the disease. Additionally, we evaluated the behavior of compost made from olive oil waste (alperujo) and the biocontrol agent Trichoderma asperellum strain T34 in two varieties of durum wheat (Duroi and Regallo). The compost showed no suppressive effect for the disease in the two varieties of wheat studied. T. asperellum strain T34 was effective against the disease in the variety Duroi (lowest dose of inoculum) and showed an intermediate effect on variety Regallo (same dose of inoculum). With the obtained results, it was determined that the most sensitive variety to the isolate of the pathogen used was Regallo. Further studies are needed to strength obtained data and also to evaluate compost from other residues as well as, different concentrations and approaches of the biocontrol agent.
