ABSTRACT

The study has been conducted in the laboratory of college of science – university of wasit in cooperation with the ministry of science and technology- directorate of agriculture research to evaluate the effect plant extract of Tagetes erecta in controlling of citrus nematode Tylenchulus semipenetrans in wasit province. The samples had been collected from citrus orchard in Wasit Province – Badrah districts and the sample includes infected roots and soil , 1.5 m away from the tree in 5- 15 cm depth and then stored in refrigerator at 4 0C . The results of this study had been revealed that the water and alcohol extracts of Tagetes erecta at all used concentrations affect the larvae of Tylenchulus semipenetrans and the effect was proportion with the concentration and exposure time and the mortality percentages of larvae treated with water and alcohol extracts were 35.66% and 34.30% respectively after 24 hours and increased to 50.68%, 58.30 %respectively after 72 hour. The highest mortality percentages of larvae were recorded at the extract concentration 2000 ppm which were 79.92%, 83.50% in the case of water and alcohol extracts respectively, while the concentration 500ppm recorded lowest percentages which were 33.54%, 38.25% respectively. The results of the study of the effect of water and alcohol extracts of Tagetes erecta on the eggs hatching showed that the extracts at all used concentrations affect the hatching of eggs significantly as compared with control and the rates of eggs hatching in the case of water and alcohol extracts were 8888%, 08.8% respectively after two days of treatment and increased to 22822%, 27808% respectively after 8 days.
