Chitosan biostimulants is obtained by deacetylation of chitosan, which is widely found in nature. CTS fertilizers have antibacterial activity and are widely used in agriculture, medicine, food, cosmetics and water treatment.
Disease control is the direction of application of chitosan biostimulants fertilizers in agriculture. Due to its antimicrobial properties, chitosan is widely used for plant protection through seed coating, soil application and foliar sprays to promote plant growth, enhance immunity and improve soil.
The mechanism of action can be divided into three main areas.
Plant resistance activation: chitosan molecules work by triggering various physiological and morphological responses in plants, establishing a natural immune mechanism. Plant resistance activation can help reduce the use of pesticides.
For example, Chitosan fertilizers can induce an immune response in plants, thereby increasing their response to pathogen invasion, thereby reducing plant disease and reducing pesticide use.
Stimulates germination: chitosan can stimulate seed germination. Chitosan soaking or coating can alter the permeability of the outer membrane of the seed, increase the concentration of sugars and proline, and increase enzyme activity. It allows seedlings to flourish.
Natural nematicide: Chitosan fertilizer applied to the soil is effective in killing nematodes. It inhibits nematode reproduction by inducing the decomposition of the chitinous matter that destroys the nematodes and their egg epidermis.
Chitosan fertilizer is widely used in commercial crops such as potato, cabbage, maize, rice, melon, tomato, lettuce and rape.
Controls insects and helps crops resist diseases.
Breaks down trace metal elements in the soil.
Strengthens plant immunity and promotes plant health.
Improves yield and quality.
Compatible with most pesticides and fertilizers.
1. High antibacterial activity
One of the most important properties of chitosan is its high antimicrobial activity against a wide range of microorganisms (e.g. fungi, bacteria and viruses).
Inhibitory effects have been observed at different stages of pathogen development, such as mycelial growth, spore formation, spore viability and germination, as well as the production of virulence factors against fungi. Dora chitosan protects against plant diseases
2. Causes plant resistance
Low molecular weight chitosan fertilizers are powerful bioinitiators.
Ability to induce plant defense responses and activate different pathways, thereby increasing crop resistance to disease. Protects against invading pathogens and harsh external environments by activating the plant's immune system.
3. For seed treatment
Chitosan have a high molecular weight and have chitosan biopolymer properties, which allows them to be used as a film that forms a physical barrier around the seeds to prevent pathogen infection.
In addition, chitosan fertilizers have been widely used in seed treatments due to their high antimicrobial activity and ability to induce plant resistance.
