One of the employed formulations in the biological control of broomrape is the application of a Pesta granular formulation using semolina, sucrose, and kaolin. In this study, the efficacy of Pseta granular formulation of Fusarium oxysporum by using 3, 5, and 10% (w/w) Psyllium seed mucilage (PSM) on Egyptian broomrape Phelipanche aegyptiaca (Pers.) Pomel. control was investigated. Natural materials were used to stimulate the germination and growth of fungal spores by providing more available foodstuffs and moisture (during the dew period) for the spores. For this purpose, an experiment was conducted in the research greenhouse during the spring and summer of 2020. The results of this study showed that the application of PSM as mucilage Pesta granules (MPGS) resulted in more effective control of Egyptian broomrape, thereby increasing the fresh and dry weight of the tomato. The lowest dry weight of Egyptian broomrape (0.22 g pot-1) and the highest dry weight of tomato (27.20 g pot-1) were observed under MPG3 treatment (10% w/w). The highest dry weight of Egyptian broomrape (1.40 g pot-1) and the lowest dry weight of tomato (21.12 g pot-1) were obtained under the MPG2 treatment (5% w/w), which was not significantly different from the control treatment (1.34 g pot-1). It was concluded that the application of PSM at 10% w/w may increase the efficacy of the Pesta granule formulation in controlling Egyptian broomrape in tomatoes.
