Several species of
nematode pests of coffee in Africa, Asia and Latin America cause serious
yield losses. Their presence often goes undetected and their effects unnoticed
or attributed to other causes. A survey carried out by Dr.
John Bridge in Tanzania in 1984 revealed a minimum of 20% loss attributable
to nematode infection in coffee plantations in the northern coffee districts.
Dr. Bridge has extensive experience of surveying, diagnosing and researching
and recommending control options for coffee nematodes in Africa, Latin
America and Asia. CABI Bioscience also has key expertise in the
accurate species identification of the nematode pests of coffee (mainly
Meloidogyne spp. and Pratylenchus spp.) by both classical
and molecular taxonomy.
