Rhamnolipids are naturally occurring glycolipids produced commercially by the Pseudomonas aeruginosa species of bacteria. P. aeruginosa produces both mono-rhamnolipids and di-rhamnolipids. Many strains of P. aeruginosa can produce rhamnolipids both aerobically and in some cases by anaerobic fermentation.Rhamnolipid biosurfactant products are currently in use as emulsifiers, dispersants, wetting agents, agricultural adjuvants, same time they can be used as Fungicide, Insecticide, Soil modifier and Chelate agent in agriculture field.
Totally green environmental friendly, all conducted under physical process, no chemicals;
The advantage of excellent surface activity and quite low CMC, can be effective at a vey low dosage;
The product is used widely due to its stable HLB value and good at emulsificating and wetting ability;
Itself can be 100% degradable, and same time biodegradation of endosulfan and other pesticides which apparent persistence and toxicity to soil, aquatic and other ecosystem ;
Test result of LD50 oral toxicity >5000mg/kg and non-toxic is in compliance with WHO standard.
One product with multi-functions, can solve problems once.
Application & dosage
The finished product of Rhamnolipids may be applied as a foliar spray, fog, drench, soil or growing media drench, preplant spray or mist on seeds, bulbs, cuttings, and transplants, in closed hydroponics systems, and through irrigation systems. To prevention and control of plant pathogenic fungi on root, bulb, tuber and cane crops.
As insecticide: A Microscopy analyses of aphids treated with dirhamnolipid revealed that dirhamnolipid caused insect death by affecting cuticle membranes of M. persicae. Rhamnolipid shows potential for use as a insecticide to control agricultural pests.
Soil modifier: Can deal with PAHs, (PH value 4.5-7) and remove heavy metal ions, (PH value 8-10). Sugessted dosage: 0.5-4%. Same time can regulate the PH value on alkaline soil to improve harden soil.
As chelate agent: With good chelate ability of metal ion chelating and even stronger than EDTA sometimes. Can be used as chaleting agent in foliar fertilizers to increase the usage of nutrition elements like Ca, Zn, Fe, and so on. According to reports Rhamnolipids either increased total plant uptake of Zn from the soil or increased Zn translocation by reducing the prevalence of insoluble Zn-phytate-like compounds in roots.
