pesticide-reduction
Pesticide-reduction encompasses strategies and research aimed at minimizing chemical pesticide use in agricultural systems while maintaining crop health and productivity. This approach is critical to plant science as it addresses the need to develop sustainable cultivation methods that preserve soil health, reduce environmental contamination, and minimize potential harm to non-target organisms. Understanding how plants can be grown productively with lower chemical inputs drives innovation in integrated pest management, plant breeding for pest resistance, and biological control research.

A natural compound found in all living cells, spermidine, can reduce pesticide buildup in strawberries while helping the plants stay healthy under pesticide stress. It works partly by blocking the same cellular transport channels the pesticide uses to move through the plant.
Spermidine significantly reduced accumulation of the neonicotinoid insecticide dinotefuran and its breakdown products in strawberry roots, stems, and leaves, with the strongest effect on migration to leaves.
Treated plants showed improved photosynthesis, higher levels of protective osmotic compounds, and reduced oxidative damage compared to untreated plants under pesticide stress.
Molecular docking and gene expression analyses revealed spermidine competes with dinotefuran for binding to ABC transporter subfamilies C and G, physically blocking the pesticide's main transport route through the plant.
