Interesting info from the 'Potential for Chitosan to
Enhance Plant Defences in Organic Systems' and a local [Aust] product name to boot
Quote:
Agricultural chitosan formulations are not readily available in Australia for trial evaluation purposes.
One chitosan was sourced from China for trial work. A formulation of chitosan called Aminogro®
was used in most of the trials. Aminogro® is the only formulation of chitosan that is produced in
Australia and which is certified as an allowable organic input.
Screening trials were conducted in tomatoes, peas, carrots, beetroot, lettuce, snow peas, cucumber and capsicums. No phytotoxicity was observed in any of the trials. In this project, trial results were most promising in tomatoes. Aminogro® chitosan resulted in yield increases of nearly 20% in two out of three tomato trials. In all tomato trials, chitosan applications resulted in a significant improvement in powdery mildew disease control.
Trial results and recent publications in international literature indicate Solanaceae plants may
respond well to plant defence booster products. Screening of plant defence booster products in potatoes is recommended for future trial work. Solanaceae crops are significant vegetable crops in Australia, and there is a potentially large target market.

, I have downloaded the PDF and will have a real close look at it this evening, there are certainly some interesting facts in it.
