Abstract:
From 1996 to 1999,the investigation of Laodelphax stratellus Fallen-a vector of maize rough dwarf virus(MRDV),the experiment of different sowing dates and MRDV disease incidence were carried out in Xinji city of Hebei.The results showed similar tend with disease incidences.All results reveased that in vector severe or moderate occurrence year,06-15 and later was the suitable sowing period.Otherwise different sowing dates had no obviously difference on disease incidence.It was concluded that sowing date was the key factor,vector number was the important factor for MRDV occurrence and spread.Therefore predicting the vector occurrence and sowing in suitable period could control MRDV disease.
