Extract

An attempt to control Graeffia crouanii (Le Guillou) with systemic insecticides injected into the trunk of coconut palms indicated a high potential for monocrotophos and dicrotophos. The fronds of 15-year-old palms treated with 6–7·5 ml active ingredient per palm were toxic to adult females for up to 16 weeks, and make a second treatment unnecessary. An analysis of coconuts from palms treated with monocrotophos (6 ml a.i.) showed no significant residues in the nut water or meat.
