Overview of squash
are many different viruses that can cause disease,
occasionally resulting in severe crop losses in squash
these viruses are well known and have been well
categorized, including identification
of their vectors and the vectors’ life cycles. However,
some of the viruses, especially the
geminiviruses, have only been identified fairly
recently, and new strains of these viruses are
being characterized on a seemingly continual basis.
viruses can be very difficult to
identify based solely on host plant symptom expression
because many of the symptoms
caused by the different viruses are very similar.
which virus (or viruses,because infections by multiple
viruses can occur at the same
time) is present, and the corresponding vector, are keys
to a virus control strategy.
