Abstract :

Potato golden cyst nematode (Globodera rostochiensis) is one of the most important diseases which causes massive damages in potato and without the management will destroy 100% of crop. In the present study, the effect of two new nematicides Nemakick and Marigold for controlling potato cyst nematode was tested. The experiment was conducted in factorial based of completely randomized design in greenhouse. Two potato cultivars Marfona (Susceptible) and Bamba (Moderately resistant) were planted and two different infection levels of 5 and 20 juvenile and egg per gram of soil and two different doses of Marigold, 150 and 300 Kgha-1 and two different doses of Nemakick, 100 and 200 Kgha-1 were applied just before planting tubers. Pots were incubated in a common greenhouse and 100 days after planting the potatoes were pulled out and population of cysts and juvenile and egg per gram of soil was counted. Potato yield factors were Also measured and the results were analyzed by SAS statistical software. The results indicated that there was a significant effect for nematode populations and potato yield parameters. Bamba showed better results compared to Marfona with respect to number of cysts, juvenile and egg per gram of soil. In Marfona nematicides scaused 35% reduction in juvenile and egg number compared to the control. Appling Marigold with 150 and 300 Kgha-1 had the maximum effect on controlling the nematode. Nemakick treatments with 100 and 200 Kgha-1.were aiso effective and acted closely to Marygold treatments.
