Nowadays, eco-friendly and green planting has become mainstream. Conventional fertilization often leads to a range of cultivation challenges, including low fertilizer use efficiency, soil compaction and continuous cropping obstacles, weak crop growth, poor stress resistance, and inferior fruit quality. Sourced from natural yeast, yeast derivatives feature high activity, zero residue and hormone-free properties, making them premium biological synergistic raw materials for fruits, vegetables, field crops, medicinal herbs and ornamental plants. They empower planting from multiple dimensions: soil improvement, root maintenance, plant stress resistance and fruit quality enhancement, precisely addressing cultivation pain points and serving as a core solution for quality improvement and yield stabilization in modern agriculture.

I. What Are Yeast Derivatives?

Agricultural yeast derivatives are natural bioactive raw materials extracted from selected high-quality Saccharomyces cerevisiae via multiple sophisticated biological processes, including biological cell wall breaking, low-temperature enzymatic hydrolysis, precise purification and fractional enrichment. Ineffective impurities and redundant components of yeast are removed, retaining high-purity and highly active natural beneficial substances. They contain no hormones, heavy metals or pesticide residues, are safe, mild and non-irritating, and fully meet the standards for green, organic and pollution-free planting. They are widely used biological stimulant raw materials in modern agriculture.

Among various yeast derivatives, yeast glycosides and yeast oligosaccharides stand out as the two most targeted and practical core products. Derived from the same source yet with distinct functions, they leverage native active nutrients from yeast to support planting by promoting crop growth and soil amelioration on one hand, and disease resistance and quality improvement on the other. They adapt well to the growth demands of various crops with stable performance and broad compatibility.

II. Analysis of Core Components of the Two Products

With exclusive purification processes, the two products feature targeted and precise components tailored to different planting needs. Their purity and activity far exceed ordinary yeast raw materials, bringing higher crop nutrient uptake efficiency and consistent effects.

1. Yeast Glycosides: Core Components

The core components are yeast polysaccharides (β-glucan + mannan oligosaccharides), amino acids, nucleic acids and other substances with stable properties and long-lasting activity. When applied, yeast polysaccharides activate the crop's own defense system, improve the rhizosphere microecology and inhibit the colonization of harmful pathogens, stimulating the growth of fine root hairs and enhancing nutrient uptake capacity. Amino acids can be rapidly absorbed and utilized by crops to supplement nutrition and relieve growth damage caused by stress. Nucleic acids participate in cell metabolism to support cell repair and regeneration, synergistically regulating crop growth, boosting stress resistance, promoting the accumulation of photosynthates, improving fruit quality, and enabling robust crop growth with stable yields and upgraded quality.

2. Yeast Oligosaccharides: Core Components

Yeast oligosaccharides are extracted from yeast cell walls, with β-glucan and mannan oligosaccharides as core active ingredients, serving as natural biostimulant essences. When applied to fields, β-glucan acts as a signaling molecule to awaken the crop's inherent defense system and improve plant resistance to diseases as well as abiotic stresses such as drought and low temperature. Mannan oligosaccharides optimize the rhizosphere microecology, facilitate the proliferation of beneficial microorganisms, inhibit the attachment and infection of harmful pathogens on root systems, and stimulate the germination of fine root hairs to strengthen root vitality and raise nutrient uptake efficiency. They coordinate vegetative and reproductive growth of crops, accelerate the accumulation of photosynthates, improve fruit coloration, sugar content and peel toughness, reduce fruit cracking, and upgrade agricultural product quality. Whether applied via foliar spraying, fertigation or drip irrigation, they can be combined with microbial agents, humic acid and other products for synergistic effects, supporting healthy crop growth, stable yields and quality improvement.

III. Core Functions of Yeast Glycosides and Yeast Oligosaccharides: Precisely Resolving Planting Challenges

The two products have respective strengths and complement each other. Used alone, they can target single planting issues; used in combination, they deliver all-round benefits including soil amelioration, seedling strengthening, stress resistance, disease prevention and quality improvement, and are applicable throughout the growth cycle of various crops.

1. Yeast Glycosides

Core Positioning: Focus on nutritional growth promotion, soil activation, fruit quality improvement and growth regulation

(1) Powerful root promotion and seedling recovery, alleviation of stunted and weak seedlings. Yeast glycosides activate the cell activity of crop roots, accelerate cell division and growth, promote sturdy elongation of taproots, dense development of lateral roots and massive sprouting of fine root hairs, and comprehensively improve the root capacity for water and fertilizer absorption. It shows remarkable effects on common problems such as slow seedling recovery after transplanting, yellowed seedlings, stunted growth, weak seedlings, aged and damaged root systems and poor vigor. It enables rapid seedling recovery, thicker stems, dark green and thick leaves, and uniform and robust plant growth.

(2) Activate soil nutrients and improve fertilizer use efficiency. It boosts the activity of beneficial soil microorganisms, improves soil physical and chemical properties, reduces nutrient immobilization and loss, greatly raises fertilizer uptake efficiency, and continuously maintains a healthy rhizosphere environment to lay a solid foundation for root growth and nutrient supply.

(3) Promote fruit color transition and sugar accumulation to upgrade fruit quality. It facilitates the transport and accumulation of photosynthates to fruits, accelerates the synthesis of anthocyanins and carotenoids, supports uniform fruit coloration, and reduces issues such as blemished peel and uneven coloring. It increases sugar accumulation and soluble solid content in fruits, strengthens peel toughness, lowers the risk of fruit cracking, optimizes fruit shape and appearance, and raises the commercial value of produce.

(4) Balance crop growth and prevent overgrowth and premature senescence. It precisely regulates the in-vivo nutrient metabolism of crops and balances vegetative and reproductive growth with bidirectional growth control: it suppresses excessive vegetative growth in the seedling stage, and prevents nutrient deficiency, leaf yellowing and premature senescence in the middle and late growth stages, stabilizing crop growth throughout the cycle and laying a solid foundation for flowering, fruit setting and stable high yields.

2. Yeast Oligosaccharides — Immune Activation, Disease & Stress Resistance, Quality Enhancement and Color Improvement

Core Positioning: Focus on disease and stress resistance, microbial community regulation and fruit quality improvement

(1) Activate crop autoimmunity and reduce disease incidence. As natural and efficient crop immune elicitors, yeast oligosaccharides actively trigger the crop's own defense system and enhance the innate disease resistance of plants. They effectively curb the spread of fungal and bacterial diseases, greatly reduce the occurrence of seedling death, root rot, wilt, downy mildew, gray mold and other prevalent diseases, cut down pesticide application frequency and dosage, and comply with green planting standards.

(2) Strong stress buffering and enhanced comprehensive stress tolerance. It rapidly scavenges harmful free radicals generated by crops under adverse conditions such as high temperature, low temperature, drought, waterlogging, salinization and continuous rainy weather, alleviates plant stress injury, effectively reduces leaf curling, wilting, flower and fruit drop, stunted fruits and other problems, ensures steady crop growth under extreme stress, and mitigates yield loss risks.

(3) Accelerate nutrient transport for fruit quality improvement and yield increase. It effectively raises crop photosynthetic efficiency and speeds up the synthesis and transport of dry matter, sugars, anthocyanins and other nutrients to precisely supply fruit expansion and development. It promotes uniform fruit enlargement, normal coloration, sugar increase and quality upgrade, reduces malformed fruits, cracked fruits and hollow fruits, and delivers well-shaped fruits with bright peel and better taste, markedly improving the commodity rate and economic value of agricultural products to achieve high quality and high yields.
