So how many of you organic farmers are using chitonase as and amendment to your soils and crops?
You know the derivatives from crab or shrimp and lobster shells. Insect frass is also a great source as well.
Studies have shown that chitonase can induce your crops SAR response by juicing up its immune system. It has also been shown to be a pest and fungal repellent.
I will post a few of the paragraphs for some of the benefits but to save space will also post the link so my fellow nerds among us can read the entire study. Most excellent read and I found it fascinating how many other uses this compound has other than the Ag industry.
I also found the link to the plants stomatal response very kool as it helps with transpration and water reduction from excessive transpiration. I use crab shells and insect frass myself but I use it in my compost pile to allow the herd and natural decomp to break the shells and frass down as it becomes more available thru the mineralisation process to be taken up by the rhizospshere when you plant.
So here are some snippets from the study. Be sure to visit the link at the bottom of the thread and read the entire paper when you get a chance.
Chitosan is derived from chitin, a polysaccharide found in exoskeleton of shellfish such as shrimp, lobster or crabs and cell wall of fungi.
Chitosan is a one of the most abundant natural amino polysaccharides extracted from the exoskeleton of crustaceans and insect, from fungal cell walls, etc.
Chitosan effects on plant response were first characterized as an elicitor. It was shown to be able to activate plant defensive genes through the octadecanoid pathway [70]. According to the defensive gene induction activity, chitosan was proved to induce disease resistance in several plants, with pathogen and plant cultivar specificity
