Abstract

After a brief review of early information on banana nematosis caused by Radopholus similis and of different concepts for its control, the author presents results from experiments conducted in West Africa to control the pest. Of the three fumigant nematicides tested (D.D., E.D.B., D.B.C.P.), DBCP was the only one recommended and used. The importance of the damage caused by the nematode was evidenced when nematicide treatments resulted in a doubling of yield; higher efficacies were obtained with the use of systemic and/or contact nematicides. Phenamiphos at dosages (g.a.i. per plant) of 3, ethoprophos at 4.5, carbofuran at 4, and isazophos at 2.5 were recommended successively. Results indicated that these four nematicides needed to be applied three times per year in a 35-cm band around the crown of each plant. Banana plants were very tolerant of these four nematicides since applications of 60 g. a.i./year divided in monthly intervals resulted in no phytotoxicity. Results also showed th
