| Abstract: | Maize rough dwarf disease,caused by RBSDV transmitted by brown plant hopper(Laodelphax striatellus),had outbroken several times and become a severe threat to maize production in recent years in part regions of Henan province.Epidemic factors leading to the outbreak of the disease were plenteous viruliferous brown plant hoppers,suitable cultivation systems for disease transmission,large scale cultivation of susceptive varieties and lack of coordinated control techniques.Based on the cultivation systems in Henan province,integrated "avoidance,elimination,resistance,prevention" control strategies were proposed,which included proper adjustment of sowing period,prediction of the disease,development and application of resistant varieties,and clearance of weeds and insects out of fields. |
