Biofertilizer based on liquid fermented with Inula viscosa, microorganisms and algae in the growth and biocontrol of Sphaerotheca pannosa var. rosae of seed rose plants

Research goal: Based on the information obtained from literature Inula viscosa, in particular insecticidal and antifungal capacities of this plant, aim work was to carry out further experiments a macerate based microorganisms algae order evaluate bio stimulant biocontrol rose plants seed. Materials Methods: The experiments, which started January 2021, were conducted greenhouses CREA-OF Pescia (Pt). experiment divided into two parts. A seed germination test plant growth test, both during same experiment. four experimental groups cultivation were: i) group without biofertilizer, irrigated with water previously fertilized substrate; ii) (INORT); iii) (Ascophyllum nodosum extract); iv) beneficial bacteria. Results Discussion: showed significant increase agronomic parameters analysed treated INORT biofertilizer roses. also greater control pathogen Sphaerotheca pannosa var. rosae seedlings sprayed biofertilizer. In fact, all height number leaves per vegetative root weight plants, duration flowers, reduction attack rosae, an average time. Conclusions: at has therefore demonstrated how application can significantly improve quality plants. As other biostimulant determined positive effects pathogenic fungi, rosae. Other investigations are currently underway study desiccant depending harvesting methods, physiological state extraction method, type culture medium, timing maceration. association various microbial consortia plant-derived biostimulants will be evaluated.
