Several key parameters were identified based on correlation analyses
between the rate of RSV diseased plants in the current pentad and
meteorological elements two pentads prior, as well as between the
rate of diseased plants in the current pentad and the amount of viruliferous
L. striatellus two pentads prior. These four parameters were the
amount of viruliferous L. striatellus, wind speed, relative humidity, and
insolation duration, and they were selected by testing the significance
level above 0.05 factor to build models.
