Tips for Diagnosing Impatiens Necrotic Spot Virus (INSV)
plants, including annuals and perennials. This virus causes symptoms that vary depending on the plant affected, but include leaf and stem spots and/or
discolouration, and stunted growth. The virus is rapidly spread by the insect vector, the Western flower thrips, and there is no cure for the disease. Due to its potential spread to other plants grown in the same area, it is very important to act quickly to remove and destroy affected plants. Therefore, a rapid diagnosis of INSV is crucial so that growers can determine if plants are diseased and act without delay.
