Protected cultivation is an emerging technology for raising vegetable and ornamental crops. Due to controlled environmental condition and continuous growing of crops, the root-knot nematode (Meloidogyne spp.) has emerged as a major problem, causing enormous yield loss. The damage progressively increases if proper sanitation control measures are not followed during the polyhouse cultivation of crops. In the absence of Methyl Bromide other fumigants like metham sodium and Dazomet have been found quite effective when used under plastic mulch for single season, non-fumigants, cadusaphos and oxamyl have also been used alone or in combination to protect 3–4 crops in protected cultivation. Combined use of bioagents, neem products and dazomet have shown promise to contain the nemic population.
