For commercial growers managing high-value fruit and vegetable crops in nematode-infested soils, Root-Knot Nematodes (Meloidogyne spp.) present a severe yield-limiting challenge. A single adult female nematode can lay hundreds of eggs encased in a gelatinous matrix attached to root tissues.
Applying G-Teck Agricultural Chitosan Oligosaccharide Powder via soil drenching or drip fertigation directly halts root-knot nematode reproduction cycles by suppressing egg hatching and juvenile emergence through a triple-action biological mechanism.
Applying G-Teck Agricultural Chitosan Oligosaccharide into the rhizosphere disrupts nematode egg masses through three distinct physiological pathways:
The structural shell of a root-knot nematode egg consists primarily of a protective chitin layer intertwined with a lipophilic vitelline membrane. Chitosan oligosaccharide acts as a specific bio-substrate for beneficial soil microbes (Streptomyces, Bacillus, Trichoderma, and nematophagous fungi like Purpureocillium lilacinum).
Applying chitosan triggers a massive population surge of these organisms, which secrete high concentrations of chitinase and protease enzymes. These enzymes digest the eggshell's structural chitin matrix, causing the egg sac to dissolve and exposing unhatched embryo larvae to desiccation.

Chitosan oligosaccharide carries a high density of positively charged functional amino groups (NH3+). The cell membranes of unhatched nematode juveniles and egg sac membranes carry a negative charge. Upon direct physical contact, the cationic polymer electrostatically binds to the lipid bilayer of larval membranes. This interaction alters cell membrane permeability, causing electrolyte leakage, internal osmotic collapse, and larval mortality before emergence. |
Beyond its direct action on egg masses, small-chain chitosan oligosaccharides () absorb into plant root tip cells. This triggers Systemic Acquired Resistance (SAR) via the jasmonic acid and salicylic acid pathways. The plant responds by synthesizing defensive secondary metabolites—such as phytoalexins, callose, and lignin—within root tissues, strengthening cell walls to prevent surviving J2 juveniles from penetrating or forming giant feeding sites.
Early Season Soil Application: For maximum control, apply G-Teck Agricultural Chitosan Oligosaccharide Powder via drip irrigation 7 to 10 days BEFORE transplanting or early in the spring root initiation phase. This primes the rhizosphere before nematode egg masses hatch.
100% Clog-Free Fertigation: Enzymatically hydrolyzed to yield a ultra-low molecular weight polymer (), the light-yellow powder dissolves completely into clear water. It leaves zero insoluble residues or fibers, protecting drip emitters, underground micro-tubes, and dosing pumps.
Synergistic Biological Co-Application: Tank-mixing chitosan oligosaccharide alongside microbial bio-nematicides (Bacillus firmus or Purpureocillium lilacinum) provides an immediate food source that accelerates microbial establishment and nematode control efficiency.
