Yield loss assessment caused by the citrus nematode Tylenchulus semipenetrans on Valencia oranges Cyprus

I. Philis

Abstract


It is estimated that the world average yield losses to citrus caused by the citrus nematode, Tylenchulus semipenetrans Cobb, are 20 to 30%. Although much research has been conducted in controlling this nematode, estimates of yield losses caused by nematode populations, in properly designed trials, are scarce. The purpose of the present study was to determine response of Valencia trees infested with different levels of citrus nematode occurring in a citrus orchard after applying three granular nematicides.
