Original title: Biostimulants in Plant Science: A Global Perspective
Biostimulants are products made from biological sources that can improve plant productivity. They may contain material from bacteria, fungi, seaweed, plants, animals, or humus-rich raw materials, and their ingredients can be prepared in many ways. The review defines them by their effect: the product works through the combined, emerging effects of its ingredients, not simply because it contains a known plant nutrient, growth regulator, or protective chemical. The authors say testing should show that a product works and is safe, and identify its broad kind of effect, even if its exact action is unknown.
Imagine making soup from ingredients gathered from many places. The taste can come from how the ingredients work together, not from one item alone. In this paper, the soup is a plant product, and its combined effect is what matters; researchers argue that it should be shown to work and be safe even if they cannot trace every effect to one exact step.
Farmers and regulators need to know whether plant biostimulants work and are safe, even when their ingredients come from many sources and their exact effects are hard to explain. The review argues that testing should focus on evidence of benefit and safety, rather than demanding a precise explanation for every product.
The abstract describes a review and a proposed definition and research approach; it does not report specific trials, measured plant-growth results, or evidence that particular products are effective or safe. It also does not identify the exact actions of individual biostimulants.
