Control of the citrus nematode (Tylenchulus semipenetrans Cobb) in Valencia orange groves in Cyprus

I. Philis

Abstract


In two experiments with Valencia orange trees, the citrus nematode (Tylenchulus semipenetrans Cobb) was effectively controlled with the granular nematicides prophos, aldicarb and oxamyl, ap2lied annually in the soil at 3, 3 and 2 g a.i./m2 , respectively. The effectiveness of the emulsifiable nematicide fenamiphos at 4 g a.i./m2 , applied with minisprinklers, lasted for three years. The most evident nematicidal effect on yield was an increase in average fruit weight (size) while in one of the trials total yield, over the 4-year experimental period, significantly increased by 9.8, 15.6 and 10.9% using the nematicides prophos, aldicarb and oxamyl, respectively.
