تاثير معاملة بذور الفول بالمبيدين في خفض نسبة الاصابة بفيروس التفاف اوراق الفول

The aim of this experiment is to study the effect of per-sowing faba bean seeds treatment with insecticide thiamethoxam (0.5 g active ingredient/Kg seeds) on incidence reduction of Bean leaf roll luteovirus in comparison with the effect of insecticide Imidacloprid (1.4 g active ingredient /Kg seeds). Results showed reduction in the viral infection rate (from 85% in control treatment dawn to 19% in Thiamethoxam treatment) when inoculation using acyrthosiphon pisum. Harris was done in early stage of plant growth, and yield reduction was decreased by 60% compared to the control treatment. Viral infection was not recorded in imidacloprid treatment in this stage and its yield reduction was decreased by 39%. The yield of non inoculated plants grown from thiamethoxam treated seeds has increased by 8% and 4% in comparison with the yield of control grown from thiamethoxam non treated seeds and from imidacloprid treated seeds respectively.
