Hermilia Sanz B. M.1

Sorne experiments were done in order to compare the efficacy on the control of sorne patogen soil borne fungi on tomato seedlings of sorne commercial systemic products (Demosan, Du Pont 1991, Plantvax and Vitavax) with sorne non systemic (Brassicol, Dexon and Mals) applied to the soil. AIso sorne systemic products (Du Pont 1991 and Vitavax) were compared with the efficiency of Arasan applied to the seed.
These experiments showed that seed applications of Arasan are as effective as soil applications of Dexon and soil applications of Brassicol. Du Pont 1991 and Plantvax were less effective than Dexon.
Soil applications of Demosan and Mals were not effective.
Vitavax was phytotoxic to the tomato plants when appIied to the soil or the seed.
