Integrated management of Meloidogyne incognita infecting Turmeric

Application of individual and combined management modules decreased root-knot index, population of nematode in soil and root including increase in various growth parameters as well as yield. Among the individual management modules, carbofuran @ 1.5 kg a.i/ha was the effective management module which enhanced plant growth, yield and reduced disease development. Although significant increase in growth, yield and disease development was recorded in T₉ (Bacillus subtilis @ 5 lit/ha + soil solarization), T₁₀ (crustacean exoskeleton @ 0.75 t/ha + soil solarization), T₁₁ (carbofuran @ 0.75 kg a.i/ha + B. subtilis @ 5 lit/ha) and T₁₂ (sesame oil cake @ 0.75 t/ha + soil solarization), T₁₁ was found to be the most important cost effective management module with a B: C ratio of 2.8: 1.
