COS(Chitosan oligosaccharide) 3000 times liquid (5g mixed with water 15kg) has a short duration of effect, but it is quick and non-toxic, and has dual biological regulation functions of medicinal and fertilizer effects. It can also promote the growth of strawberries while inhibiting powdery mildew.
Applications of LIN-COS can be in new biological fertilizers (plant growth regulator, foliar fertilizer, flushing fertilizer, seed coating agent) and biological pesticides,etc.

LIN-COS is Chitosan Oligosaccharide, also known as chitosan oligosaccharide and oligochitosan, is a kind of polymerization degree obtained by degrading chitosan by special biological enzyme technology The oligosaccharide product with a molecular weight of ≤3200Da is a low molecular weight product with good water solubility, large functional effect and high biological activity. It has higher solubility than chitosan, is completely soluble in water, and is easily absorbed and utilized by organisms. It has 14 times of its function as chitosan.
Chitooligosaccharides are the only positively charged cationic basic aminooligosaccharides in nature and are animal cellulose.
Plant responds to infection using an innate immune system.
Metarhizium anisopliae is a fungal insecticide, and conidia is the effective component of its insecticidal activity.
When conidia contacting and attaching to cockroach, it germinates and penetrates the cockroach body walls; then invades into the body, grows and reproduces rapidly in the blood of the cockroach, and compete for the nutrients with the tissues of cockroach, making them weak and stop feeding.
At later stage, the fungi secretes toxins, which affects the central nervous system of cockroach, destroys its various organs, and dehydrates its tissues, then causes death of cockroach.
The hyphae of Metarhizium anisopliae in the dead cockroach extend through the internode membrane and produce conidia.
The conidia continue to infect other pest individuals through contact infestation or air-borne and wind diffusion, and form repeated infestation in the roach population.
Application of in different period of rice growth
Remarks: increase the dosage of Metarhizium anisopliae OD for the outbreak of rice planthopper and leaf roller, the volume should be increased to 5-6 times more than that of the normal.
