A resistência sistêmica induzida como alternativa sustentável ao uso de agrotóxicos

Abstract

New control technologies against phytopathogens that would neither harm people nor damage the environment have become indispensable as alternatives to pesticides in agriculture. Induced Systemic Resistance (ISR) is the activation of the plant's natural defense system derived from specific compounds and which promote a wide protection spectrum to different cultures of economic relevance without any damage to consumers or the environment. Several biotic and abiotic ISRs already on the market or under analysis have been evaluated for the control of pathogens that attack vegetal varieties in Brazil. The compounds represent a promising sustainable option in the control of pathogens and guarantee efficiency in the production and commercialization of cultures in a more ecologically correct way, economically viable and socially just manner.
