Abstract

Reducing the usage of pesticides is of great importance for a sustainable agriculture and bioeconomy. Insect pests and microbial pathogens are major causes of crop and fruit damages worldwide, representing losses of US$500 billion/year. Within the Pro-Planta proposal, two technologic platforms will be developed and evaluated to reduce the use of antimicrobials in citrus protection against citrus canker. Citrus canker is a disease caused by the bacteria Xanthomonas citri subsp. citri (Xac) and X. fuscans subsp. aurantifolli; it may lead to defoliation, dieback and premature fruit drop, generating great losses in fruit production and quality. Brazil is currently the largest producer of oranges in the world, generating over US$2 billion/year in export revenues. From 2009, the legislation for the control of citrus canker in São Paulo state was relaxed, and according to the current rules (resolution SAA - 147 of 2013), growers are obliged to eliminate the infected trees in the orchards and to spray copper formulations within a radius of 30m from a contaminated tree. After these changes, the incidence of citrus canker increased by 80% and now there is a real risk of citrus canker becoming endemic in the state of São Paulo. Finally, the constant use of copper sprays may leave residues in fruits and soil with risks to human health and agricultural production; besides, it contributes to the emergence of copper-resistant bacterial strains. The Pro-Planta project team aims to develop and validate two broadly applicable protection platforms for pest management and reduced use of bactericides/copper. Platform (a) is composed of bifunctional fusion proteins (Ieaf binding and antimicrobial function) which stick to citrus leaf surface and platform (b) is based on microgels containers which are bound to citrus through an anchor peptide and loaded with gallates (antimicrobial agent) for slow and demand-dependent release. A demand matching, rain-independent and long-Iasting compound release of gallates shall reduce pesticide consumption and will contribute to a sustainable and integrated bioeconomy in which discipline boarders are bridged.
