Two granular formulations of Fusarium oxysporum f.sp. orthoceras to mitigate sunflower broomrape Orobanche cumana
BioControl 49 (5), 595-602
Abstract: Fusarium oxysporum Schlecht. f.sp. orthoceras (Appel and Wollenw.) Bilai, a potential biocontrol agent against Orobanche cumana Wallr., was formulated into two granular forms, wheat flour kaolin (`Pesta') granules and sodium alginate pellets. The formulations were compared in terms of effectiveness for mitigating O. cumana parasitism in sunflower and shelf-life for storage. `Pesta' granules reduced the emergence of O. cumana shoots by 64% while sodium alginate pellets did not reduce the emergence rate but increased the percentage of diseased O. cumana plants. Calculated efficacy of the application was better for `Pesta' granules. Viability of the formulated material tested in the laboratory was higher in sodium alginate pellets than in the `Pesta' formulation. However, a loss of virulence after six months of storage was also observed in sodium alginate pellets in a greenhouse experiment.
