Chitosan oligosaccharide (COS) can improve plant summer stress resistance
In summer, the sun is scorching and rain comes and goes. So plants face the dual challenges of high temperature, drought and heavy rain. As agronomists, we have found that chitosan oligosaccharide is an effective new “escort” tool to help plants maintain healthy growth under such extreme weather conditions.
COS is a natural polysaccharide substance prepared from chitosan through a special enzymatic hydrolysis process. It has a variety of biological activities and plays an important role in plant growth.
How does chitosan oligosaccharide help plants resist high temperature and drought?
Maintain water balance:
COS can enhance the strength and stability of plant cell walls. At the same time, it can reduce water evaporation, help plants better maintain water balance and reduce stress under drought conditions.
Promote antioxidant defense:
Under high temperature and drought conditions, plants are susceptible to oxidative stress, so lead to the accumulation of oxygen free radicals and damaging cell structure and function. Chitosan oligosaccharide not only can increase the antioxidant enzyme activity of plants, but also can reduce the production of oxygen free radicals. And it can enhance the antioxidant defense capabilities of plants.
How does chitosan oligosaccharide cope with the challenge of heavy rain?
Improve soil water permeability:
COS can improve the structure of the soil, increase the stability of soil aggregates, improve the water permeability and air permeability of the soil, reduce soil loss. Meanwhile it is beneficial to the respiration and growth of plant roots.
Enhance disease resistance:
Heavy rains can easily lead to the reproduction and spread of pathogenic microorganisms in the soil, causing plant diseases. Chitosan oligosaccharide not only can activate the plant’s defense system, but also can enhance the plant’s resistance to pathogenic microorganisms, and reduce the risk of disease.
How to use chitosan oligosaccharide correctly?
COS can be introduced into plants through foliar spraying, soil application, etc. And can be used in small amounts and multiple times to improve the stress resistance of plants.
Summer is a critical period for plant growth. COS as a natural, safe and effective biostimulant, provides important protection and support for plants.
