Different letters within the same column mean significant differences at p ≤ 0.05
(1) Damage 0-5 (Campbell and Shishkoff, 1990)
(2) Percentage of total root damage caused by the complex Rhizoctonia solani, F. oxysporum f. sp. lycopersici and P. lycopersici
(3) Harvest up to 3^rd bunch in June 8, 2002.
(4) Applied as Metabromide 980 (98 MeBr : 2 chloropicrine) in a dosage of 75.5 g/m² before transplanting (January 17, 2002). Application: November 28, 2001. Aeration until January 10, 2002.
(5) Trichoderma harzianum was applied to the soil 7 days before transplanting (1 g pellet (4.2 x 10⁶ cfu/g pellet)/L soil)
(6) Solarization (November 28, 2001 – January 10, 2002).
(7) Paenebacillus lentimorbus application: 2 ml (5 x 10⁹ cfu/ml)/seedling in the speedling, 10 days before transplanting.
