Abstract

The effect of organophosphorus nematicides (cadusafos, ethoprophos), and carbamates, (aldicarb, carbofuran) on citrus nematode (Tylenchulus semipenetrans) population densities was determined in sandy clay loam soil. Results indicated that all evaluated nematicides reduced population densities vastly throughout seven months from the duration of the experiment after treatment, where efficiency reached 83.2 %, then nematicides efficiencies decreased sharply for next months for them except carbofuran. Data analysis indicated that there are significant reduction in population densities on citrus nematode between cadusafos and ethoprophos and other nematicides used in 1st to 4th months, while significant differences was obtained between control and tested nematicides.
