Plant immune inducers are substances that enhance a plant’s disease resistance by activating its own immune system. Chitooligosaccharides (COS) are a prominent example of this class, functioning through multiple mechanisms to induce resistance. The following sections outline the concept of plant immune inducers and the specific functions of chitooligosaccharides. What Are Plant Immune Inducers? Plant […]

In the field of plant nutrition, EDTA (ethylenediaminetetraacetic acid) is a widely used synthetic chelating agent. Its core function is to act like a miniature “molecular protective shield,” encapsulating trace metal ions (such as iron, zinc, manganese, and copper) essential for plant growth. This shield effectively prevents these key nutrients from “losing” due to chemical

In modern precision agriculture, liquid fertilizers are increasingly widely used due to their advantages such as rapid absorption, high uniformity, and ease of fertigation. However, liquid fertilizers, especially high-concentration micronutrient liquid fertilizers, face a core technological challenge: nutrient precipitation and inactivation. The key to solving this problem lies in chelating agents. Chelating agents are crucial

γ-Aminobutyric acid (GABA) and Glycine betaine are two classes of small-molecule compounds that have garnered significant attention in the study of plant stress physiology. Although not essential nutrients, they play a crucial protective role when plants encounter adverse conditions—effectively acting as “stress-resistance agents” synthesized by the plants themselves. Whether accumulated endogenously or applied exogenously, these substances

γ-Aminobutyric Acid (GABA) is a non-protein amino acid widely distributed in plants, playing a central role in regulating plant growth, maintaining cellular homeostasis, and mediating plant responses to biotic and abiotic stresses. Functioning as both a metabolic intermediate and a signaling molecule, GABA integrates with various amino acid metabolic pathways to form a highly coordinated regulatory

Although micronutrients (such as boron, zinc, iron, manganese, copper, molybdenum, and chlorine) constitute only one ten-thousandth to one thousandth of the dry weight of plants, they are the “lifeblood” determining high yield, high quality, and stress resistance in modern agriculture. Most of them participate in life activities in the form of enzyme cofactors or electron

Glycine betaine is a natural, non-toxic, water-soluble alkaloid widely used in agriculture as an exogenous plant growth regulator. In rice, its primary role is to systematically enhance the plant’s resistance to various stresses; building upon this protection, it promotes growth and development, ultimately leading to stable or increased yields and improved quality. Strengthening Stress Resistance:

The majority of all fungal formulations contain Trichoderma spp., making them effective biological control agents for agriculture. Chitosan, one of the most effective natural biopolymers, was also reported as a plant resistance enhancer and as a biocide against a variety of plant pathogens. An in vitro three-way interaction assay of Trichoderma atroviride, chitosan, and important

Seed treatment constitutes the first critical gateway in the crop life cycle, directly influencing germination rates, seedling vigor, and ultimate yield. While traditional seed treatments have primarily relied on chemical fungicides and insecticides, biostimulants—a novel class of agricultural inputs—have gained widespread adoption in the field of seed treatment in recent years, distinguished by their ability

Against the backdrop of global agriculture facing the dual challenges of food security and environmental protection, biostimulants—a novel class of agricultural inputs—are garnering increasing attention. Among these, microalgae are emerging as a research hotspot within the biostimulant field, thanks to their unique biochemical properties and multifaceted functions. Microalgae are microscopic, photosynthetic, autotrophic organisms capable of
