A Quantitative Study on the Epidemic Dynamics and Economic Loss Caused by Maize Rough-Dwarf Virus Disease
Abstract: In this work, the dynamics of maize rough-dwarf virus(MRDV)epidemics and the economic loss due to the disease were studied using data recorded from naturally infected field maize crops. MRDV epidemics were found to develop during the growing season following the logarithmic parabola(LP), thus models for their progressing on Zhongdan 2 and Danyu 13 maize crops were established by fitting observed data to the LP function y=a?exp(b?x+c?x~2), The LP function is considered general for modelling progress curves o...
