Curvularia eragrostidis (Ascomycota: Dothideomycetes) was recently reported as the causal agent of Pineapple Leaf Spot disease (MD2 hybrid) in Central Pacific Mexico. Therefore, the effectiveness of five chemical fungicides (System Cu®, Tilt® 250 CE, Volley® 88OL, Tecto 60® and Mancozeb® 80WP) at four concentrations (1.0%, 0.5%, 0.25% and 0.125%) was evaluated through a doses response bioassay. The DGR of C. eragrostidis was 1.5 cm/day. The fungicides Volley® and Tilt® at the four evaluated concentrations did not allow the growth of C. eragrostidis. The lowest DGR for System Cu®, Mancozeb® 80WP and Tecto® 60 was found at the dose of 1% with 0.13, 0.0 and 0.39 cm / day, respectively. The %IMG for Volley® and Tilt® 250 CE were 100% at all evaluated doses. For System Cu®, Mancozeb® 80WP and Tecto® 60, the %IMG ranged from 65.2 (0.125%) - 78.2 (1.0%), 62.9 (0.125%) - 100.0 (1....
