Diagnostic summary
-
Specific virus diseases can rarely be diagnosed on the basis of
visible symptoms alone. The purpose of this fact sheet is to cover
those cases where symptoms suggest a virus problem, but are not
sufficiently specific to identify which virus is responsible.
-
Symptoms may include mild to moderate growth reduction, mild chlorosis or mottling, pale spots or veins and leaf deformities.
-
Yield decline may be the only indication of problem. It may
not be recognised unless virus-free plants are grown for comparison.
-
New infections appear on individual plants. However,
infections are spread through planting material from one generation to
the next, and after a few years all plants are likely to be
infected.
-
Virus-infested plants may show little response to fertilizers,
even where responses in other crops suggest that the fertilizers are
needed.
