The role of phytochemical diversity in the management of agroecosystems

Biodiversity in ecosystems is crucial providing ecosystem services and their stability resilience. However, most studies supporting the benefits of biodiversity crop health were studied at cultivar scale, generally without specifying resistance mechanisms involved crops to pests. Thus, it unclear if phytochemical diversity one those whether patterns processes which can be replicated or adapted management sustainable agroecosystems. Here, I review roles natural determine they helpful briefly (a) spatial temporal structure its effect on plant consumers; (b) how that generated maintained; (c) current potential role The ?-, ?-, ?-phytochemical diversities are very high landscapes; gets displayed dynamic mosaics mixtures secondary metabolites vary concentration composition within among individuals, populations, species. Phytochemical fostered by evolutionary coevolutionary processes, mainly under an arms-race scenario. idiosyncratic depending identity interacting species local biotic abiotic environment; thus, copy them industrial agroecosystems hardly viable. five recommendations could agroecosystem made.
