Abstract
Plant virus diseases cause major losses in agricultural and horticultural products, especially in tropical and subtropical regions. The first step to manage these diseases is detecting, identifying and determining the pathogen characteristics. Cucumber mosaic disease is one of the most prevalent and damaging plant diseases in the world which is caused by Cucumber mosaic virus (CMV). Each year, this virus causes yield decreasing and substantial economic damages in its host plants worldwide including the north of Iran. In order to study and identify CMV, 935 leaf samples were collected based on typical symptoms from 10 crops (tomato, pea, tobacco, soybean, watermelon, broad bean, squash, cucumber, eggplant and lettuce) in different regions of Golestan and Mazandaran provinces (north of Iran) during 2009–2010. Suspicious samples were analysed by DAS-ELISA and polyclonal antibodies. The results showed that 275 samples (29.4%) were infected by CMV. Between these hosts, the highest and the lowest CMV infection was associated to watermelon (62.44%) and lettuce (0%), respectively. Among sampling locations, Behshahr (100%) and Minoodasht (3.47%) showed the maximum and minimum infection, respectively.
