Abstract

The objective of this work was to evaluate a phytoprotective film of chitosan-pyroligneous extract in promoting growth, productivity, induction of systemic resistance in strawberry cultivars managed in an organic production system. Treatments consisted of rates (0, 25, 50, and 100 mL L-1) of Chi-Pyro-Film and a reference resistance inducer (dipotassium hydrogen phosphate - K2HPO4), 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-1, according to strawberry cultivar.
