ると言う問題点がある。However, among the above-mentioned conventional methods of applying chitosan to trees, the method of spraying it as an aqueous solution is not effective because it is scattered in the air or washed away by rain or the like, and is not supplied to the trees. It should be thin, and should be applied frequently,
Mixing powder into solid fertilizer does not have rubber-like flexibility and processability, and crab shells and shrimp shells give off an offensive odor due to the denatured protein components contained in it, or animals do not react with soil. There is a problem that it may be dug up and pests such as slugs may multiply.
