Dear John:
               RED alert. As you could see in any book dealing with plant 
viruses, leafhoppers are among the most efficient vectors of these incurable 
diseases. They are particular to certain plants (here to Salvias) so it is 
easy to monitor their occurrence in which case a systemic insecticide is the 
best solution, its effect usually lasting for a whole three week period.  A 
small scale attack is not so terrible, the problem is when leafhoppers stay 
for long enough to spread viruses from weeds to our collections!
No mercy, zero tolerance and good luck
