Abstract

Treatment of tomato plants with T. asperellum-based products formulated with the T asperellum's conidia suspension, without talc (P1) and with added talc (P2) reduced verticillium wilt. The Dwarfing index (SI) of plants treated with P1 and P2 were -4.25% and -6.95% respectively, compared to 6.178% for plants inoculated with V dahliae alone. Treatment with P2 promoted the development of the agronomic parameters followed by P1 in comparison with the water control and the inoculated control. The average weight of tomatoes harvested from each of the plants inoculated with V. dahliae and treated with P1 and P2 was respectively 194.17 g and 235.43 g / 148.40 g and 90.03 g. On the other hand, treatment of the plants with 40 ml of the conidial suspension volume, prepared from a fresh culture or product P2, increased all the agronomic parameters of the plants compared to the other tested volumes and the water control. The aerial part length is 111.17 cm and 115 cm/ 97.16 cm. The fresh roots weighed 118 g and 139.23 g / 42.07 g. The tomatoes weighed 122.07 g and 148.77 g/12.56 g.
