Wheat (Triticum aestivum cv. Lakhish) seeds were coated with Promet 666, a seed dressing formulation of furathiocarb, a systemic soil insecticide, at 5 and 15 ml/kg seeds. This treatment was evaluated for Pratylenchus mediterraneus control and wheat grain yield and compared with soil application of a granular formulation of Promet and with a nontreated control. AU Promet treatments reduced the nematode population level and increased the yield. The best nematode kill (75%) was achieved by the soil application, followed by the high-dosage seed dressing (50%). The highest yield was obtained in the high-dosage seed dressing treatment, followed by the soil application. The results suggest that seed dressing protects the germinating seedling from nematode attack at the critical stage of its root system development. © 1987 Springer Science + Business Media B.V.
