Abstract
Surveys showed that high mosaic incidence (85%) in pepper fields is caused
mainly by Cucumber mosaic virus (CMV), Potato virus Y (PVY) and
Tobacco mosaic virus (TMV). Diagnosis of the individual viruses was based
on their reaction on indicator plants, physical properties and serology. TMV was
the only virus transmitted by pepper seeds at the rate of 11%. All three viruses
were found to naturally infect weeds. Green peach aphid efficiently transmitted
CMV and PVY. Natural infection with these viruses significantly reduced wet and
dry weight and affected the content of nitrogen, phosphorus and potassium, and
also reduced chlorophyll content by 70%. Using corn plants as barrier reduced
infection. Spray with mineral oil reduced the rate of CMV and PVY transmission
by aphids
