Abstract
Cucumber is an important vegetable cultivated under polyhouse conditions in the tropical and sub-tropical regions. Cucumber production is majorly limited by infection of root-knot nematode Meloidogyne incognita and is considered to be an important pest causing severe yield loss. In this study, the presence of M. incognita infecting cucumber under poly house condition in Theni Tamil Nadu was confirmed. Among ten polyhouses surveyed, cucumber cultivated under four polyhouse is infected with M. incognita and infestation ranged from 21 to 33%. Nematode infested plants expressed the typical symptoms viz., stunting, and withering, drooping and sudden wilting of plants. Application of biocontrol agent like Purpureocillium lilacinum or newer chemicals like Fluopyram or Fluensulfone is effective for the management of root-knot nematodes.
