摘要
玉米粗缩病由灰飞虱传播,病原主要是水稻黑条矮缩病毒(RBSDV),近年来其在河南省局部地区多次暴发,对玉米生产造成严重威胁。该病暴发流行的原因为带毒虫量大,耕作制度适合病害传播,感病品种大面积种植,联防意识缺乏等。并结合河南省生产实际,提出了适当调整播期,预测预防病害发生,选育利用抗病品种,清除田间杂草和虫源等的"避、除、抗、防"综合防治策略。
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.
