Effects of Heterodera Sacchari Population Density on Establishment and Development of Upland Rice Cv. DSA6 under Field and Pot Conditions

Discipline: Agriculture, Pest Science



In West Africa, the cyst nematode Heterodera sacchari is known to cause stunting and chlorosis of upland rice. Studies have also demonstrated its high pathogenicity on susceptible cultivars (Babatola 1983, Coyne and Plowright 1998).

We studied the effect of the nematode on rice (cv. IDSA6) development in a naturally infested field site at the West Africa Rice Development Association (WARDA), Côte d’Ivoire, and in 100-mL pots in the screenhouse.
