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 December 6, 2001.
(4) Trichoderma harzianum was applied to the soil 7 days before transplanting (1 g pellet (4.2 x 10⁶ cfu/g pellet)/L soil). When used along with P. lentimorbus, it was applied to the soil at the time of transplanting.
(5) Paenebacillus lentimorbus application: 2 ml (5 x 10⁹ cfu/ml)/seedling in the speedling, 10 days before transplanting.
(6) Applied as Metabromide 980 (98 MeBr : 2 chloropicrine) in a dosage of 75.5 g/m² before transplanting (July 15, 2001). Application: June 28, 2001 – July 3, 2001. Aeration until July 5, 2001.
