Abstract

Abstract: Southern rice black-streaked dwarf virus (SRBSDV) is a kind of ruinous rice virus disease transmitted by the whitebacked planthopper. Basing on the occurrence and harm of SRBSDV in Huazhou district from 2009 to 2016, with recognization of the disease symptom and insect vector of SRBSDV, the essay analyzes that the severity of SRBSDV is related to vector numbers, viral source capacity, rice species, planting patterns, rice sowing period, seedling bed position and climate condition. The control strategy, which includes putting forward prevention and control technology, cutting off viral source, defending against insects, is proposed for comprehensive application. The synthetical preventing SRBSDV technical system which adapts to rice region in the western part of Guangdong province is implemented. The technical system is promoted and applied in production. With the measures above, the epidemic risks of SRBSDV can be prevented and controlled to obtain remarkable social and economic benefits.
