Treatments consisted of rates (0, 25, 50, and 100 mL L<sup>-1</sup>) of Chi-Pyro-Film and a reference resistance inducer (dipotassium hydrogen phosphate - K<sub>2</sub>HPO<sub>4</sub>), evaluated in three strawberry cultivars ('Albion', 'San Andreas' and 'Portola'). Growth, yield, anthracnose incidence, and enzymatic activity were evaluated. The experimental design was a randomized block design with four replications. Chi-Pyro-Film increases the growth, yield, and anthracnose resistance of strawberry plants. The best concentration of Chi-Pyro-Film varies between 50 and 60 mL L<sup>-1</sup>, according to strawberry cultivar.</strong></p> ER -
