Abstract:

Maize virus disease is a systematic infestation disease, and a disease on maize causing serious damage and difficult to control. In order to clear the pathogen and epidemiology of the disease raising and spreading in recent years in maize main production area in northwest Zhejiang, to present control technology, we had investigated and researched to the pathogen, virus transmitting vector, epidemiology, disaster causes and IPM technology in 2008-2011. The results showed that, maize virus disease occurring in Lin’an was maize dwarf disease, or maize rough dwarf disease; it was caused by the virus RBSDV, small brown plant hoppers (SBPH) were the insect vector. The disease’s epidemiology were related with the SBPH vector population dynamics and ratio of the vector insects with virus, climate, variety resistance, sowing and planting timing and rice status of infestation. The control strategies and integrated control technology to the disease were presented and extended spreading on maize production in large scale, the damage of the disease was effectively controlled, good harvest was insurance, significant economic and social effeciency were acquired.
