ey points of application of chitosan in agriculture (3)

① The role of chitosan in agriculture has an important relationship with the concentration of chitosan solution.

The chitosan solution used in agriculture is generally formulated with acetic acid. Usually use 1%～2% B

Acid, prepared into a solution with a chitosan concentration of 1%, that is, containing 1g of chitosan in 100ml of the solution. In specific use, the chitosan solution with a concentration of 1% needs to be diluted to different concentrations. For different purposes, different crops, and different application methods, the dilution concentration is also different. If the concentration is too large or too small, it will affect the effect of chitosan.

②Different molecular weights and different derivatives of chitosan have obvious effects in agricultural applications.

same. For example, chitosan has a more obvious effect in inhibiting pathogenic bacteria, improving antibacterial activity and resisting diseases and insect pests.

③The safety of chitosan

Chitosan is a pure natural animal polysaccharide obtained by processing the chitin of shrimp and crab. It is non-toxic and harmless.

Crops, humans, animals, and the environment will not cause any pollution. Therefore, the use of chitosan in agriculture is a very safe biotechnology. It is impossible to treat grains, vegetables and other foods with chitosan. There are any residues of harmful chemicals such as pesticides.
