Black spot disease is a global plant disease caused by various fungi (mainly *Alternaria*), posing a serious threat to agricultural production. Chitosan oligosaccharide, a highly effective plant immune inducer derived from marine organisms, has been extensively studied and proven to effectively control black spot disease through a dual pathway of “direct inhibition” and “resistance induction.” […]
What is Chitosan Oligosaccharide (COS) and Its Market Demand Chitosan Oligosaccharide (COS, also named Amino‑oligosaccharin) is low‑molecular‑weight water‑soluble oligosaccharide obtained by enzymatic or chemical degradation of chitosan, which is converted from chitin. Chitin widely exists in crustacean shells, insect exoskeletons, fungal cell walls and partial algae. Chitosan Oligosaccharide features a degree of polymerization ranging from

Chitosan can play a key role in modern agriculture production and could be a valuable source promoting agricultural ecosystem sustainability. Future suggestions will be based on current achievements and also notable gaps. In addition, chitosan has a huge contribution to reducing fertilizers pollution, managing agricultural pests and pathogens in modern-day agriculture. The overwhelming demand for
In plant physiology and modern agriculture,γ-aminobutyric acid (GABA) andγ-polyglutamic acid (γ-PGA) are attracting increasing attention as two substances with significant biological activity. Despite their similar names, they differ significantly in chemical structure, mechanism of action, and application: GABA is a small-molecule non-protein amino acid that primarily functions as a signaling molecule in plant stress responses;
The roles of macronutrients in plants can be summarized into three core functions: constituting living matter, driving energy metabolism, and regulating physiological activities. Each element possesses unique and irreplaceable functions, collectively sustaining the plant’s complete life cycle from seed to seed. Biostimulants supplement plants with macronutrients not merely through simple addition, but primarily through two

In the field of agricultural disease control, Chitosan Oligosaccharide and Microorganisms represent two distinct yet synergistic strategies. Chitosan Oligosaccharide act as a “dual-action weapon,” capable of both directly attacking pathogens and actively priming the plant’s own immune system; meanwhile, microorganisms (primarily antagonistic bacteria) serve as “biological guardians,” establishing a dynamic biological defense line through mechanisms such as
Using biostimulants for pest control is a cutting-edge and highly promising area of current agricultural research. The core concept is not to “kill” pests—as traditional pesticides do-but rather to activate the plant’s own immune system and defense mechanisms, making the plant unpalatable or inhospitable to pests, thereby achieving pest control indirectly. It functions more as

The combination of Chitosan oligosaccharide and Trichoderma harzianum represents more than a simple additive effect when combating soil-borne pathogens; it is a multi-dimensional, synergistic strategy that directly inhibits pathogens from the outside while systematically mobilizing the plant’s own immune system from within. Various formulated products and field application protocols have already been developed, and their efficacy
The core dilemma facing modern agriculture lies in a tripartite challenge: achieving high crop yields and superior quality (which demands ample nutrition); contending with frequent abiotic stresses—such as drought, soil salinity, and extreme temperatures (which necessitates robust stress tolerance); and avoiding phytotoxicity resulting from the improper use of pesticides (which requires safety assurance). Traditional agrochemicals
As a crucial component in pesticide formulations, surfactants act synergistically with pesticides to significantly enhance solubility, improve dispersibility, and optimize wetting properties. Consequently, this leads to increased biological activity, reduced application rates, and enhanced stability. Based on their surface-active characteristics, pesticide adjuvants can be broadly categorized into two major groups: surfactants and non-surfactants. Surfactants, defined
Bacillus species and related genera, such as Paenibacillus and Priestia, combine several useful traits, including phosphorus solubilization, nitrogen fixation, production of growth hormones, enzyme release, and generation of antimicrobial compounds. These abilities improve nutrient use, protect plants from pathogens, and increase stress tolerance. Applied as single strains or in microbial consortia, they have consistently increased
In today’s era—marked by the transition of traditional agriculture toward sustainable, efficient, and eco-friendly practices—peptides are emerging as a pivotal bridge connecting fundamental research with practical field applications. Peptides are small-molecule compounds composed of amino acids, typically comprising fewer than 100 residues. Compared to conventional fertilizers and pesticides, peptides offer distinct advantages, including multifaceted functionality,
