%X the work was made in the plant phytopathology laboratory belonging to the scientific and technological base unit base los palacios. the aims of this research was to evaluate the antifungal activity of four chitosan formulates q (100, 500, 1000 mg.l-1) y chitosan and copper (qcu-100 mg.l-1) on the mycelial growth and in vitro sporulation rate of pyricularia grisea sacc fungus. results showed that 1000 mg.l-1 chitosan and qcu-100 mg.l-1 had the greatest inhibitory effect on four day with 27 y 30 %, respectively. however fungal sporulation was inhibited in 100 % by el qcu, while q 100 y q 500 had inhibitory percentages between 80 y 96 % on center and peripheral zones respectively. in addition, q-l000 mg.l-1 chitosan had not a noticeable effect on fungal sporulation.
