chitosan

Chitosan is a natural, safe, and cost-effective biopolymer derived from amino-deoxy-D-glucose, produced through the de-acetylation of chitin. Chitin is the primary component of the exoskeletons of arthropods, such as lobsters, shrimp, and crabs, as well as insects and fungi cell walls. It is the second largest renewable carbon source after lignocellulosic biomass. Due to its affordability, biodegradability, non-toxicity to the environment, and biocompatibility, chitosan is an ideal resource for sustainable agriculture, enhancing soil health, and boosting crop growth and yield. Additionally, it is increasingly utilized in cosmetics, food, animal feed, and medicine.

However, chitosan’s limited solubility in water poses challenges to its use and agricultural effectiveness. Chitosan oligosaccharide, or oligo-chitosan, is a smaller polymer derivative, containing fewer than 30 amino-glucose molecules and a molecular weight of less than 3000 Daltons. This is achieved through the enzymatic hydrolysis and truncation of chitosan. The low molecular weight of oligochitosan makes it water-soluble, offering ease of use, enhanced bioavailability, compatibility, and improved functional efficacy.

What does Chito-Magic Oligochitosan do

1. Accelerate germination and growth;
2. Improve yield and quality of flowers and fruits;
3. Helps prolong shelf life and prevents early decays when applied on to fresh produce;
4. Allows the plants to grow with less water;
5. Boost defense of plants against diseases and resilience during heat/cold stress and drought.

Application Guide

1. Dissolve in water to make 4% Oligochitosan solution. Foliar spray 10-200 ml/acre or 25-500 ml/ha, every 7-10 days.
2. Apply three or more foliar applications during the crop cycle at key plant growth stages.
3. This product is compatible with most liquid fertilizers, pesticides, herbicides and insecticides. Jar test is recommended for first time use.
4. Wear protective gloves and goggles. Wash thoroughly after handling.

FAQs

Q: What is chitosan oligosaccharide?

A: Chitosan oligosaccharide, a.k.a oligochitosan, is enzymatically degraded chitosan, with lower molecular weight and higher solubility in water. It is a newer generation of chitosan for better efficacy and easier application.

Q: Can oligo-chitosan be used together with common fertilizers and pesticides?

A: Yes. Oligo-chitosan is compatible with most fertilizers and pesticides.
