A Review of Experiments on Nematode Control with Ethoprop (Prophos); Phenamiphos and Carbofuran in French-Speaking West Africa

Resumen

The new grandular nematicides phenamiphos, ethoprop and carbofuran have been evaluated in a series of experiments in West Africa. Recommendations are that phenamiphos (3g a. i.), ethoprop (4.5g a. i.) and carbofuran (3g a. i. except in Cameroon) should be applied to 1m around each plant 3 times per yr at intervals determined by the distribution of rainfall. Granular nematicides have been found to be more effective than DBCP and to improve production; however, the main disadvantage is that the new products are very expensive.
