Abstract
This study evaluated a β-D-1,6-glucan derived from the regional oomycete Lasiodiplodia theobromae, comparing its effectiveness with the traditional elicitor ASM in inducing post-harvest resistance in grapes and promoting sustainable practices. Commercial grape varieties (Bordô and Niágara Rosada) were sourced locally and treated with water (Control), β-D-1,6-glucan (200 mg L⁻¹), or ASM (Bion® 500 WG, 100 mg L⁻¹). Grapes treated with β-D-1,6-glucan consistently showed a tendency for lower AUDPC (Area Under the Disease Progress Curve) values across both varieties and injury conditions. In wounded Niágara grapes, ASM initially showed a tendency to reduce AUDPC until the 8th day, but β-D-1,6-glucan had the lowest value by day 10. β-D-1,6-glucan-treated fruits also had the highest Total Phenol Content (TPC) and pulp firmness compared to those treated with ASM or water. This study underscores β-D-1,6-glucan’s potential as a natural alternative to synthetic fungicides, enhancing grape resistance to Glomerela cingulata, extending shelf life, and reducing environmental and health impacts.
