Good results in postharvest Botrytis control in strawberry by applying salicylic acid in the field

Strawberry is a high economic value crop, which in postharvest is highly susceptible to the attack of the pathogenic fungus Botrytis cinerea; for its control, one of the widely used methods are pesticides; however, exposure to these remains an important health and environmental problem. In this sense, the need to seek alternatives for sustainable management arises. The objective of the present work was to evaluate the effect of salicylic and ascorbic acids as inducers of resistance to Botrytis cinerea in post-harvest strawberry fruits. Strawberry plants (Fragaria x ananassa Duch cv. Camarosa) were sprayed twice weekly with solutions of salicylic acid, ascorbic acid and water as a control. The results showed significant differences in salicylic acid at a concentration of 1.5 ?M, with less than 1 % damagein the fruits, despite not inhibiting the appearance of the fungus, delaying its appearance, besides increasing the yield so that it can represent an alternative to the useof pesticides. Conclusions are that the investigation indicates that the foliar application of salicylic and ascorbic acid did not induce resistance to the pathogen Botrytis cinerea, nevertheless, results suggest that the salicylic acid at a 1.5 ?M could extend postharvest life of the strawberry by reducing the expression time of the pathogen, maintaining the quality and decreasing the use of pesticides; however, further studies to completely understand the mechanism by which acids can influence in the resistance induction to pathogens in the different varieties of strawberry Fragaria sp are necessary.
