对邹平县１９８４年和１９９６年玉米粗缩病大流行情况进行了调查研究。结果表明，该病初侵染来源广且重的地方发病重；春玉米发病最重，其次为麦套玉米；玉米品种间发病轻重有一定差异；玉米有阶段抗病性，罹病愈早，受害愈重。从压低毒源和虫源入手，制订了小麦玉米一体化、大范围、群防群治的防治策略，并采取农业、化学等综防手段，防效明显。
In Zouping County in 1984 and 1996 maize disease pandemic were investigated. The results showed that the disease was mainly originated from a wide range of sources and severe in weight. The incidence of spring maize was the highest, followed by that of wheat maize. The maize varieties had some differences in their severity of disease.

From the point of view of reducing the source of poison and the source of insects, we formulated the prevention and cure strategies for the integration of wheat and corn, large-scale and mass prevention and mass control and adopted the comprehensive prevention measures such as agriculture and chemistry to prevent obvious effects.
