ABSTRACT
The effectiveness of using Gaucho® (imidacloprid) for seed dressing used different cultural practices to reduce the natural infection by Faba Bean Necrotic Yellows Virus (FBNYV) in faba bean crop. The results of seed dressing by Gaucho were obtained in the growing season 2007/08 and 2008/09 growing seasons. In 2007/08 growing season showed that seed dressing with Gaucho was effective in reducing FBNYV from 44.50% in plant without treatment to 8% only when used the concentration 2 g / kg seeds. The results in 2008/09 growing season showed that seed dressing with Gaucho was effective in reducing FBNYV from 52.6% in plant without treatment to 5.6% only when used the concentration 2 g / kg seeds. In 2007-2008 growing season from the obvious results found that the better result when we used insecticide Peremore 0.2% with used rouging, the percent of disease incidence was 10.7% followed by using Masrona oil was 22.7%, and 27.8% with used rouging with K.Z oil and the percentage of disease incidence was 46.5% with used rouging and used Nestapon. On the other hand, the control treatment with rouging and without using any insecticide or detergents the disease incidence was 59.6 % in 2007-2008 growing season. In 2008-2009 growing season, the disease incidence was 21.3% followed by using Masrona oil was 41.25% and without rouging with K.Z oil was 48.75%; the disease incidence was 61.25% with using Nestapon and without rouging. On the other hand, the control without using any insecticide or detergents and without rouging the disease incidence was 87.87%.
