These studies coincide with research conducted by Jaber and Alananbeh [103], in pepper plants which provided evidence that commercial strains of *B. bassiana* (Naturalis) and *M. brunneum* (Bipesco5) can inhibit the growth of several species of *Fusarium* (*F. oxysporum*, *F. culmorum*

With the increase of the world population, it is urgent for the development of sustainable strategies to improve food availability. *Capsicum annuum* is an excellent source of natural health-related compounds, such as micronutrients and antioxidants; its fruits have been used for fresh and cooked consumption. The crop of this vegetable can be negatively affected by biotic factors, provoking decreased yields. In this chapter reviewed, we have provided evidence of the potential that microorganisms present for the control of insect pests, plant diseases, and nematodes in the *Capsicum* crop. There are a significant number of investigations carried out under laboratory conditions with good biocontrol results; however, it is necessary to increase the number of field studies and application methods, since environmental
