Dominant Plant-Parasitic Nematodes in Sugarcane crop: A Affliction to Sugar Production.
Dr. Resha
Abstract:
Sugarcane is a significant crop globally, but its production is threatened by plant-parasitic nematodes, particularly Meloidogyne and Pratylenchus species. Estimated annual losses: $100 billion globally. These nematodes attack sugarcane roots, causing stunted growth, reduced yields, and lower sugar content. The two most common types or class of plant-parasitic nematodes, these are ecto-parasitic &endo-parasitic include Meloidogyne (root-knot), Heterodera (cyst), and Pratylenchus (lesion) species. These nematodes use complex mechanisms to invade and manipulate plant cells, suppressing plant defenses and creating a nutrient-rich environment for themselves. Plant-parasitic nematodes are challenging to manage due to their underground habitat, high reproductive rates, and ability to survive in soil for extended periods.
