Abstract: The present study refers to the effect of endophytic insect pathogenic fungus on the growth of tomato crops. It can colonize a wide variety of plants and can cause increased plant growth and protect against parasites (Canassa, 2019). Specifically, the fungus used is Beauveria bassiana Balsamo (Vuillemin) (Hypocreales: Cordycipitaceae) after isolation in target insects, which is considered insect pathogenic and endophytic. The aim is to investigate the effect of the insect pathogenic fungus as endophytic on the growth of plants belonging to important crop vegetables, such as tomatoes. The study is of great significance, as the evidence of the use of the fungus with this technique will be used as an innovativeeconomic strategy for the improvement and growth of plants without additional nutrients (Tall and Meyling, 2018). It is defined as a biological treatment other than systematic human intervention since Beauveria bassiana spends all or part of its life cycle intracellularly or/and between cells forming colonies in healthy tissues of their host plants typically without causing obvious disease symptoms (Wilson, 1995).
