A virulent strain of B. cinerea isolated from tomato-infected leaves and stored in silica gel crystals at 4C was cultivated in mixed vegetable solid medium for 21 days at 20C, 7 days under dark conditions, and 14 days at PPFD 85lmol m2 s1 and 16 h light. The mixed vegetable medium was prepared by cooking 500 g of a commercial frozen mix of potato, carrot and beans in water.Theboiledvegetablesandcookingwaterwerehomogenized with a kitchen blender, the volume was brought to 1 L and 150 mL of the mixture plus 7.5 g of agar were used to prepare 500 mL of mixed vegetable medium. Conidia were collected from the plates in an inoculation buffer containing 0.5 mg mL glucose and 0.5 mg mL1 KH2PO4 (De Meyer et al., 1998). Twelve mL of the buffer was used per plate; the resulting suspension was filtered through two cotton gauzes. The concentration of B. cinerea was adjusted to 105 conidia mL 1 by hemocytometer counting. Finally, a drop of Tween 20 was added to the inoculum (0.005%) to promote uniform dispersion of the inoculum on plants leaves.
