Against the backdrop of the global transition towards green and sustainable agriculture, how to improve crop yield and quality through safe and efficient means has become a focus of both scientific research and industry. In recent years, mannose, as a natural monosaccharide, has gradually entered people's field of vision due to its potential in plant physiological regulation, disease prevention and control, and soil microecology improvement. As a new choice for green agriculture, mannose is providing new assistance for the healthy growth of crops.

1、 Basic characteristics of mannose

Mannose is a monosaccharide widely present in nature, commonly found in certain plant cell walls, polysaccharides, and microbial metabolites. It can be converted into key energy substances through metabolic pathways in plants and participate in various signal regulation processes. Compared with traditional sugars, mannose is not only an energy source, but also has regulatory functions, which provides a scientific basis for its application in the agricultural field.

2、 The mechanism of promoting healthy growth of crops

①. Energy and metabolic support

Mannose can serve as a substrate for plant energy metabolism, providing support for root development and leaf photosynthesis. Under certain stress conditions, mannose can be rapidly converted into glucose or other metabolites, providing immediate energy to crops and helping them resist environmental stress.

②. Enhance resilience

Research has found that mannose can induce the expression of stress related genes in plants, improving their tolerance to adversity such as drought, salinity, and low temperature. By adjusting osmotic pressure and cell membrane stability, mannose improves crop adaptability while reducing the adverse effects of environmental pressure on growth.

③ Potential for disease prevention and control

Mannose plays a special role in the interaction between plants and pathogens. Some pathogens may be disturbed by mannose signaling when recognizing plant cell walls, thereby reducing infection efficiency. In addition, mannose can serve as an inducer to stimulate systemic acquired resistance (SAR) in crops, enabling plants to quickly initiate defense responses when encountering diseases and reducing pesticide dependence.

3、 Exploration of Application in Agricultural Production

①. Crop growth regulator

Using mannose as a foliar spray or rhizosphere irrigation component can promote seed germination, root development, and seedling growth. Especially in facility agriculture and efficient intensive planting, mannose has shown promising application prospects as a green growth promoter.

②. Green prevention and control measures

In crop disease control, mannose can serve as an auxiliary factor for biological control, replacing or reducing the use of some chemical pesticides. For example, in the cultivation of high value-added crops such as fruit trees and vegetables, mannose treatment can reduce the incidence of diseases and avoid the threat of pesticide residues to food safety.

③. Improvement of soil microecology

Mannose can also serve as a nutrient source for beneficial microorganisms, promoting the reproduction and stability of rhizosphere probiotic communities, and improving soil structure and microecological environment. By optimizing the rhizosphere environment, the nutrient absorption efficiency and overall health level of crops are improved.

With the deepening of agricultural modernization and green transformation, the potential application of mannose is gradually being explored. The future development trends are mainly reflected in the following aspects:

·Combining with biologics: Combining mannose with biopesticides and microbial fertilizers to form a composite green product, achieving dual functions of crop nutrition and prevention and control.

·Precision agriculture application: In the context of smart agriculture, dynamic regulation of crop growth is achieved through precise monitoring of crop growth stages and stress, scientific application of mannose.

·Priority promotion of high-value crops: being the first to be applied in economic crops, specialty fruits and vegetables, and medicinal plants, improving product quality and market competitiveness, and providing a new path for agricultural efficiency improvement.
