¹Fungal strain inoculated at seedling transplant (3-5 true leaves).
²Fungicide specific for fungi of Rhizoctonia genre, applied to soil as recommended by the manufacturer (0.15 cc/pot).
³Bioantagonists formulated in sodium alginate, were applied to the soil at seedling transplant. Formulations contained: Th650 (4.9 x 10⁵ cfu/g), Th650-NG7 (5.1 x 10⁵ cfu/g), Th12 (3.8 x 10⁵ cfu/g), Th12A10.1 (5.6 x 10⁵ cfu/g), Th11 (1.2 x 10⁵ cfu/g), Th11A80.1 (7.9 x 10⁵ cfu/g) and Th11C40.1 (10.4 x 10⁵ cfu/g).
