Phytoextracts as Crop Biostimulants and Natural Protective Agents—A Critical Review

Excessive application of synthetic chemicals to crops is a serious environmental concern. This review suggests that some potential natural compounds can be used as alternatives and could applied directly plants improve crop growth productivity. These phytoextracts serve biostimulants induce abiotic biotic stress tolerance in different growing under diverse conditions. The biosynthesis accumulation variety chemical such glycinebetaine, vitamins, nutrients, secondary metabolites are great value an environmentally friendly cheaper source than several substances similar nature. summarizes the information regarding role plant subsequent applications modulate tolerance. Future studies should focus on relative effectiveness these plant-based extracts compared with their counterparts practical signify sustainable practices linked use products.
