Abstract

Plant parasitic nematodes are major pests of agronomically important crop plants and cause an estimated $100 billion in damage annually worldwide (Koenning et al. 1999). These microscopic invertebrate pests attack all types of plants. These include the major cereals, rice, wheat and corn, potato, tomato, vegetable crops, trees, ornamentals, turf grass, and other plants. In fact, more than 200 species of plant parasitic nematode are reported to attack rice alone (Prot et al. 1994)! Crop rotation is often used to help alleviate nematode damage to crops. Poor and non-hosts must be alternated with the susceptible crop in the cropping sequence to minimize nematode damage. Chemical control can be costly and can damage the environment. Nematodes can have a large and broad host range, but many have a restricted host range. For example, in the genus Meloidogyne, some members can reproduce on a wide range of vegetable crops, such as potato and tomato, while only some populations can reproduce on a few hosts (Moens et al. 2009).
