he study included testing the effectiveness of biosynthetic zinc nanoparticles from the fungus A.niger and the aqueous extract of sisban blocks on plant height, number of branches and dry weight of beans infected with charcoal rot disease caused by the fungus Macrophomina phaseolina. The effect of nanoparticles and aqueous extract was tested at three concentrations ( 1000, 2000 and 4000 ppm).. The results showed that high concentrations of nanoparticles contribute to supporting plant growth and increased by a significant difference from the control treatment. When testing its effectiveness in increasing plant height, it was found that the highest height was when treated with nanoparticles loaded on the fungus A.niger (Z1), as it reached Plant length 27.7 As for its effect on dry weight, the best treatment was nanoparticles loaded on A.niger fungus mixed with sesban plant (Z1S0), as the weight reached 2.6 g. Also, the treatment Z1S0 gave the best result in increasing the number of branches, as it reached 5.2.
