Root-knot nematodes are a type of plant-parasitic pest with many species, of which 13 are currently known. Among them, root-knot nematodes are the most harmful to crops and can affect a wide range of crops, causing irreparable losses. They are one of the most difficult soil-borne pathogens to prevent and control in the world.
According to statistics, nematodes cause crop losses of up to $157 billion globally each year! Generally, they reduce yield by 20% to 50%, making them the second-largest category of crop diseases.
Root-knot nematodes can induce multinucleate giant cells in host root cells, which then absorb large amounts of nutrients from the plant to sustain their growth and development. This significantly weakens the plant's ability to absorb water and provide nutrients, causing disruption in the distribution of photosynthetic products, stunting plant growth, resulting in shorter plant, yellowing leaves, and even premature death, ultimately leading to reduced crop yield or crop failure. Plants invaded by nematodes are easily infected by soil-borne pathogens.
Root-knot nematodes have four life stages: egg, larva, adult, and cyst. Eggs hatch from cysts and become second-stage lavras, which can infect plant roots. They penetrate the roots through tips or wounds and then grow and develop within the roots, maturing into white female adults. The female adults attach to the root surface and produce egg-laying structures called cysts, which fall to the soil and remain dormant overwinter. They can cause nodular root knots to form on the roots, reduce the number of root hairs, and cause stunting and yellowing of the above-ground parts, similar to symptoms of lack of nutrients.
Three major advantages:
1. Comprehensive control of nematodes: The combination of deep-sea oligosaccharins and Fosthiazate kills both nematodes and eggs, doubling the effective control effect.
2. Promote root growth: Multiple root-promoting functions work together, starting from promoting wound healing and tissue regeneration, promoting the development of weak seedling root systems and recovering root systems, improving crop disease resistance.
3. Induce immunity: Effectively improve crop immunity, enhance water and nutrient absorption capabilities, promote early and rapid crop growth, improve quality, and increase yield.
