The present study was performed in order to determine the efficiency of the fungi Aspergillus alliaceus in fighting broomrape by the pesta-tablet trials under below- and above-ground conditions and to determine the appropriate tablet formulations for both conditions. For this purpose, different tablets were used in different experimental steps and their efficiencies were evaluated. The results showed that the tablets T-1, T-2, T-3, T-5, T-12 and T-13 greatly reduced the amount of broomrape in below-ground conditions, particularly with previous and high amount or crushed-tablet applications before crop-sowing. In above-ground conditions, any tablet formulation or directly sclerotial contacting were very effective in broomrape control and it was determined that close presence to or direct contact with broomrape is essential for successful biocontrol. In conclusion, considering the durability of the fungal agent against harsh environmental conditions and its sclerotial structure, it was deduced that if the fungi could be implemented in a stand-alone or especially integrated with each other, it will provide long-term, high-level broomrape biocontrol, indicating the advantages of A. alliaceus against other alternative fungal agents. |
