Agricultural Rhamnolipids ABG-P & ABG-PJ

1. Basic information

Agricultural rhamnolipids are glycolipid metabolites produced by specific microorganisms through fermentation technology. There are two specific models, ABG-P (without bacteria) and ABP-PJ (with bacteria). Agricultural rhamnolipid is a new type of biological additive that can be used in fertilizers, pesticides and functional agricultural products.

The most significant advantage of special agricultural rhamnolipids is that they are of natural origin, safety, environmental protection and no residue. It can be applied in the whole agricultural industry, such as seed cultivation, soil improvement, fertilizer efficiency, plant nutrition, plant protection, fruit and vegetable preservation, etc.

3. Features

  • Synergies

Agricultural rhamnolipids have lipophilic and hydrophilic surface activities, so they can reduce surface and interfacial tension, and have the functions of solubilization, emulsification, penetration, and wetting. The lipophilic and hydrophilic groups of the product can form a directional adsorption film in the plant wax layer and fertilizer solution, and reduce the surface tension and contact angle. Therefore, it can promote the absorption of nutrients in fertilizers and increase the absorption efficiency of fertilizers by plants. After a large number of field experiments, it is proved that the special agricultural rhamnolipid can reduce the fertilizer consumption by about 1/3 (up to 2/3 in some cases) without reducing the original fertilizer efficiency.

  • Stable efficacy

Agricultural rhamnolipids have strong thermal stability, chemical stability, temperature and salt resistance. Its stock solution still has good application performance at 150°C and 100000mg/L salinity.

  • Soil remediation

The chelating (composite) effect of agricultural rhamnolipids can absorb and repair the structure of soil aggregates and enhance soil permeability. Its effect of activating soil microorganisms can improve the soil micro-ecological environment and repair soil compaction. It also has a good pH buffering effect on salinized and saline soil.

  • Chelating (complexing) ability

The double carboxyl structure of agricultural rhamnolipid makes it have chelating (complexing) function. The carboxyl group can fix the middle and trace elements around the root system, alleviate the element loss, enhance the fertilizer efficiency, and ensure the long-term effectiveness of the fertilizer. At the same time, because the elements and glycolipid molecules are in a chelated (complexed) form, they are lipophilic, and highly fat-soluble substances are more likely to enter plant cells through the lipid bilayer of the cell membrane. This characteristic of agricultural rhamnolipid improves the absorption and conduction utilization rate of middle and trace elements, and ensures the long-term effect of fertilizer.

  • Plant growth promotion function

Agricultural rhamnolipids have good biological stimulating functions and certain plant growth regulating functions. It has certain effects on growth promotion, stress resistance, disease resistance, and bacteriostasis.

  • Degradability

Agricultural rhamnolipids are biodegradable. Experiments show that it can reach 7 days and 100% degradation under standard experimental conditions. In plants, the degradable metabolism is completed in 7 days. The degraded agricultural rhamnolipids become nutrients for environmental microorganisms, which does not cause secondary pollution to the environment.

 4. Application Suggestions

  • Add 2-5% to the fertilizer formula.
  • The finished fertilizer is recommended to be diluted 300-500 times.
