The effects were investigated of soil moisture, soil pH, drought and nitrogen and phosphorus applications on the development of Meloidogyne graminicola on rice in India. Larval invasion was greatest in soils at 32% moisture content; development and egg mass production were greatest at 20 to 30% soil moisture. Greatest larval invasion was at pH 3.5 but pH did not affect invasion, growth or development of the nematode to any significant extent.
